Study points to quality issues in Bt Cotton seeds

[vc_row][vc_column][vc_column_text]Sunderarajan Padmanabhan

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.

Lok Sabha clears bill to levy cess on pan masala and similar goods for health, security funding

The Lok Sabha has passed a bill to impose a cess on pan masala manufacturing units, aiming to create a dedicated revenue source for public health and national security initiatives.

Nirmala Sitharaman

The Lok Sabha has approved the Health Security se National Security Cess Bill, 2025, paving the way for a new cess on pan masala manufacturing units. The legislation aims to generate dedicated funds for strengthening national security and improving public health, both areas identified as critical national priorities.

Bill aims to create predictable funding stream

Finance Minister Nirmala Sitharaman, responding to the debate before the bill was passed by voice vote, said that the cess will be shared with states because public health falls under the state list.

The new cess will be applied over and above the GST, based on production capacity and machinery used in units manufacturing pan masala and similar goods. The minister clarified that this cess will not affect GST revenue, and that pan masala already attracts the maximum GST slab of 40 per cent.

According to the bill text, the objective is to build a “dedicated and predictable resource stream” to support expenditure related to health and national security.

Sitharaman also mentioned that cess collection as a percentage of gross total revenue currently stands at 6.1 per cent, lower than the 7 per cent average between 2010 and 2014.

Simone Tata passes away at 95: A look at the visionary who shaped Lakme and modern retail

Simone Tata, the pioneering business leader who built Lakme and helped shape India’s modern retail sector, passed away at 95. Here’s a look at her legacy.

Ratan Tata’s stepmother and celebrated business leader Simone Tata passed away on December 5, 2025, at the age of 95. Known for her pioneering role in building Lakme and transforming India’s retail landscape, she leaves behind a remarkable legacy that redefined Indian consumer culture.

A legacy that shaped Indian business

Simone Tata, born in Geneva in 1930, first came to India at the age of 23. Two years later, in 1955, she married Naval H. Tata and gradually became an integral part of the Tata family’s business vision. Her journey with the Tata Group began in the 1960s, when she was appointed to Lakme—then under Tata Oil Mills.

Under her leadership, Lakme quickly grew into one of India’s most trusted cosmetic brands. She rose to the position of managing director and later chairperson, introducing global formulations and modernising beauty products for the Indian market. Lakme’s rise was also rooted in a strong national vision—launched on former Prime Minister Jawaharlal Nehru’s suggestion to reduce foreign exchange spent on imported makeup.

Transforming retail through Trent and Westside

After Lakme was sold to Hindustan Lever Limited in 1966, Simone moved to Trent, where she helped build one of India’s earliest modern retail chains. This later gave birth to Westside, a brand that has become synonymous with contemporary Indian shopping culture.

She also played a key role in philanthropic initiatives, guiding organisations such as the Sir Ratan Tata Institute and supporting cultural and children-focused foundations.

Family, personal life and final farewell

Simone Tata is survived by her son Noel, daughter-in-law Aloo Mistry, and grandchildren Neville, Maya and Leah. She also drew public attention in recent years for being the only member of the Tata family to attend Cyrus Mistry’s funeral, despite the widely known strained ties between the families.

Her funeral will take place on Saturday morning at the Cathedral of the Holy Name Church in Colaba, Mumbai.

Centre orders probe into IndiGo crisis, expects normal flight operations in three days

Amid record cancellations by IndiGo, the Centre has ordered a high-level inquiry and expects flight schedules to stabilise by Saturday, with full normalcy in three days.

The Centre has initiated a high-level inquiry into the massive disruption of IndiGo’s operations, with the government projecting that flight schedules will begin stabilising by Saturday and full normalisation is expected within three days. The announcement comes as cancellations by the airline crossed 500 for the second consecutive day, severely impacting passengers across major airports.

Civil Aviation Minister Ram Mohan Naidu said the government has directed urgent measures to ensure swift restoration of services. Within minutes of his statement, the aviation regulator DGCA announced the formation of a four-member committee to examine the circumstances leading to the delays and cancellations.

DGCA forms committee as cancellations spark scrutiny

The DGCA said IndiGo was given sufficient time to implement revised Flight Duty Time Limitations (FDTL), yet the airline recorded the highest number of cancellations in November. The regulator added that the pattern suggested gaps in the carrier’s internal oversight and preparedness, warranting an independent probe.

The committee will review the sequence of events that triggered disruptions and recommend measures to prevent a recurrence.

Flight duty rules relaxed; minister defends move

Amid criticism from the Opposition and experts, the DGCA temporarily suspended certain FDTL rules, increasing pilot duty limits from 12 to 14 hours. The changes were widely questioned, with allegations that the government was yielding to pressure from IndiGo.

Naidu defended the decision, stating the move was taken solely to safeguard passengers and that safety standards would not be compromised.
He reiterated that passenger care and convenience remain the top priority.

Assurance of refunds, real-time updates, and support

Highlighting steps taken to ease passenger distress, the minister said airlines must:

  • Provide accurate, real-time updates before travellers leave for airports
  • Initiate automatic refunds for cancelled flights without requiring follow-ups
  • Arrange hotel accommodation for passengers stranded for extended periods

Senior citizens and persons with disabilities have been accorded special priority, including access to lounges and additional assistance. Refreshments and essential services are to be provided to all affected travellers.

Inquiry to determine accountability

The government said the high-level probe will identify what went wrong at IndiGo, establish responsibility, and recommend systemic corrections to ensure such disruptions do not occur again.
