Study points to quality issues in Bt Cotton seeds

The controversy over poor ‘refuge’ for genetically modified cotton, known as Bt Cotton, has taken a new turn with a study showing that not only farmers but seed companies are responsible for the problem.

Conducted by Indian Council of Agricultural Research (ICAR)’s Nagpur-based Central Institute for Cotton Research (CICR), the study has found several lacunae: admixture of the refuge seeds with Bt seeds, poor germination of non-Bt seeds and asynchrony between the Bt and corresponding non-Bt refuge, in contravention of the regulatory guidelines. Researchers have published their findings in the latest issue of journal Current Science.

The purpose of refuge area in which non-GM cotton is grown is to delay the development of resistance in bollworms. The efficacy of refuge depends on the extent of simultaneous flowering and fruiting of the refuge and the main Bt crop. The Genetic Engineering Approval Committee (GEAC) had stipulated that a minimum of five border rows of conventional non-Bt Cotton hybrid of the corresponding Bt hybrid should be planted as refuge around Bt Cotton field. This norm was also subsequently amended to allow planting of pigeon pea as refuge crop. Seeds companies were required to provide a packet of 120 g non-Bt cotton seeds or 200 g of pigeonpea along with every packet of 450 g Bt Cotton seeds.

The study, conducted in 2014 and 2015, has found that seed companies have violated these norms. In the first year, 91 Bt Cotton seed packets were purchased from open market in North and Central India and a random sample of 10 seeds each from the main packet and the non-Bt refuge packet were drawn for the study. The seeds were first analysed to see what they contained. As many as 26 refuge packets had Bt seeds, when they should not have even a trace of them. Clearly there was an admixture of the refuge seeds with Bt seeds.

This was followed by a field trial. It wasconducted at the institute with 45 Bt-refuge seed pairs to study the level of germination and synchrony between them in flowering and fruiting.There was not much difference in terms of germination: all the Bt seeds had a germination of over 75 per cent, while 40 of the refuge had a germination of over 75 per cent and the balance five less than 25 per cent. However, when it came to flowering, for which 40 sets were assessed, there were issues: there was synchrony only in the case of 17 pairs.

In 2015, 30 seed packets were procured from the open market in Central India and studied. Here again 12 packets for refuge seeds were found to contain Bt seeds. On further study, while all the 30 Bt hybrids had a germination of over 75 per cent, only nine refuge seed had a germination of over 75 per cent.

Studies over the years have indicated that the refuge compliance was poor, leading to rapid development of resistance in pink bollworm for CryIAc and Cry2Ab toxins. So far, the blame was laid mainly on the farmers. It was thought that their ignorance of the need for refuge and reluctance to sacrifice land for non-Bt crops that would be vulnerable to bollworm was mainly responsible. The new findings change this.

The study also assumes importance in the context of a proposal to introduce a new concept called ‘refuge in bag (RIB)’ under which the farmers would be provided with a seed mix of 5 per cent non-Bt refuge and 95 per cent Bt seed in a 475 gm packet. The idea is to ensure that famers do not have the choice of avoiding refuge planting. But, it remains to be seen how far it will really help. For, with the present method of testing 10 seeds per packet, monitoring the correct percentage of non-Bt seeds in a bag of Bt seeds is likely to be difficult.

Delhi’s air quality has continued to deteriorate, prompting authorities to enforce Stage-III measures under the Graded Response Action Plan (GRAP) across the National Capital Region with immediate effect.

The Commission for Air Quality Management (CAQM) said the Air Quality Index (AQI) of the national capital showed a worsening trend over the past 24 hours. The AQI stood at 343 on January 15 at 4 pm and rose further to 354 by 4 pm on Thursday, raising concerns that pollution levels could soon enter the ‘Severe’ category.

Weather agencies have forecast unfavourable atmospheric conditions in the coming days, including low wind speeds, a stable atmosphere and poor dispersion of pollutants. Officials said these conditions could push Delhi’s average AQI beyond 400, which falls under the ‘Severe’ air quality bracket.

Stage-III restrictions come into force across NCR

In view of the rising pollution levels and the forecast of further deterioration, the CAQM sub-committee on GRAP decided to invoke all measures under Stage-III. These measures correspond to ‘Severe’ air quality levels and have been implemented as a precautionary step to prevent further decline.

The Stage-III actions will be enforced in addition to the restrictions already in place under Stages I and II of GRAP, which remain operational across the NCR. Officials said the combined measures aim to tighten controls on pollution sources, enhance monitoring and ensure stricter enforcement to curb emissions.

CAQM has directed pollution control boards and concerned agencies in the NCR to intensify preventive and regulatory steps. Authorities have been asked to ensure strict compliance with GRAP norms and take prompt action against violations.

Officials said air quality levels will be closely monitored, and further decisions will be taken based on real-time data and evolving weather conditions. Citizens have been urged to cooperate with advisories and follow measures aimed at reducing pollution levels.

Prime Minister Narendra Modi will visit West Bengal and Assam on January 17 and 18, where he will flag off India’s first Vande Bharat sleeper train and inaugurate, dedicate and lay the foundation stone for a series of infrastructure and development projects across the two poll-bound states.

Vande Bharat sleeper train to be flagged off from Malda

On Saturday, the prime minister will visit Malda in West Bengal around 12.45 pm and flag off the country’s first Vande Bharat sleeper train connecting Howrah with Guwahati (Kamakhya) from the Malda town railway station.

Later in the day, around 1.45 pm, he will address a public programme in Malda where he will dedicate to the nation and lay the foundation stone of multiple rail and road projects worth more than Rs 3,250 crore.

Development projects in Hooghly district

On January 18, around 3 pm, the prime minister will visit Singur in Hooghly district, where he will inaugurate, lay the foundation stone and flag off various development projects worth around Rs 830 crore.

During the visit, Modi will also virtually flag off four new Amrit Bharat Express trains connecting New Jalpaiguri with Nagercoil and Tiruchirappalli, and Alipurduar with Bengaluru and Mumbai (Panvel). These services are aimed at improving affordable long-distance rail connectivity and strengthening inter-state economic and social linkages.

New train services and highway projects in north Bengal

The prime minister will flag off two new train services with LHB coaches — Radhikapur–SMVT Bengaluru Express and Balurghat–SMVT Bengaluru Express — providing direct connectivity from north Bengal to major IT and employment hubs.

He will also lay the foundation stone for the rehabilitation and four-laning of the Dhupguri–Falakata section of National Highway-31D, a project expected to significantly improve road connectivity and the movement of goods and passengers in the region.

Additionally, Modi will lay the foundation stone of four major railway projects in West Bengal, including a new rail line between Balurghat and Hili, next-generation freight maintenance facilities at New Jalpaiguri, upgradation of the Siliguri loco shed and modernisation of Vande Bharat train maintenance facilities in Jalpaiguri district.

He will also dedicate the electrification of the New Coochbehar–Bamanhat and New Coochbehar–Boxirhat rail sections, enabling cleaner and more energy-efficient train operations.

Cultural programme and Kaziranga corridor in Assam

On January 17, around 6 pm, the prime minister will attend the Bodo cultural programme “Bagurumba Dwhou 2026” at Sarusajai Stadium in Guwahati. More than 10,000 artists from across Assam are expected to perform the traditional Bagurumba dance in a single synchronised presentation.

On January 18, around 11 am, Modi will perform the bhoomi pujan for the Kaziranga elevated corridor project, valued at over Rs 6,950 crore, at Kaliabor in Nagaon district. The 86-km project includes a 35-km elevated wildlife corridor passing through Kaziranga National Park, along with bypasses and highway widening works aimed at improving connectivity while protecting biodiversity.

During the Assam programme, the prime minister will also flag off two new Amrit Bharat Express trains — Guwahati (Kamakhya)–Rohtak and Dibrugarh–Lucknow (Gomti Nagar) — strengthening rail connectivity between the northeast and northern India.

NDA’s track record strikes chord as PM Modi hails Maharashtra civic polls win

Prime Minister Narendra Modi hailed Maharashtra voters after the BJP-led NDA registered a historic victory in the BMC elections, ending decades of Shiv Sena dominance.

Prime Minister Narendra Modi on Friday thanked the people of Maharashtra after the BJP-led National Democratic Alliance registered a landmark victory in the Brihanmumbai Municipal Corporation elections, marking the first time the party has emerged on top in the country’s richest civic body.

In a post on X, the prime minister said the people of the state had endorsed the NDA’s agenda of governance and development. He said the results of municipal corporation elections across Maharashtra showed that the alliance’s bond with voters had further strengthened.

According to PM Modi, the NDA’s track record and vision for development had “struck a chord” with the electorate. He described the verdict as a mandate to accelerate progress while celebrating Maharashtra’s cultural legacy.

BJP-Shiv Sena alliance dominates BMC

As counting continued, trends showed the BJP leading in 90 of the 227 wards in Mumbai, while the Eknath Shinde-led Shiv Sena was ahead in 28 wards. The Ajit Pawar-led NCP faction, which contested separately, was leading in only three wards.

On the opposition side, the Shiv Sena (UBT) and Maharashtra Navnirman Sena were ahead in 57 and nine wards respectively. The Congress, which contested in alliance with the Vanchit Bahujan Aghadi, was leading in 15 wards, while others were ahead in eight.

The outcome effectively ends the Shiv Sena (UBT)’s decades-long control over the Brihanmumbai Municipal Corporation, which had been the party’s main power centre since its formation.

In the seat distribution, the BJP contested 137 wards and the Shinde-led Shiv Sena 90. The Ajit Pawar faction of the NCP fielded candidates in 94 wards. On the opposition side, Shiv Sena (UBT) contested 163 seats, the MNS 52, the Congress 143, and the Vanchit Bahujan Aghadi 46.

Urban verdict weakens Pawar influence

The results in Pune and Pimpri-Chinchwad also sent a strong political message, indicating that the Pawar brand no longer guarantees success in key urban centres. Despite tactical coordination between the two NCP factions led by Sharad Pawar and Ajit Pawar, voters did not consolidate behind them.

In the Pune Municipal Corporation, the BJP emerged with a clear upper hand, either winning or leading in a significant number of wards. The NCP factions failed to convert their traditional influence into broader citywide support.

Thackeray retains Marathi Manoos connect but loses power base

Uddhav Thackeray appears to have retained a section of the Marathi Manoos vote in Mumbai, even as the Shinde-led Shiv Sena made inroads. While the Shiv Sena (UBT) managed a respectable showing in its traditional strongholds, the loss of control over the BMC is seen as a major setback.

Control of the civic body had long been central to the party’s political identity and a key factor in its alliances.

Devendra Fadnavis emerges as key strategist

Much of the credit for the BJP’s sweeping civic success is being attributed to Devendra Fadnavis. Under his leadership, the Mahayuti alliance has carried forward its assembly election momentum into municipal politics.

The results are being seen as reinforcing Fadnavis’s political standing, demonstrating that even combined opposition forces could not halt the BJP’s rise. The verdict has also challenged the long-held claim of the Thackeray family over Marathi votes in Mumbai.
