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.

PM Modi accuses Congress of anti-Sikh bias over Rahul Gandhi’s ‘traitor’ remark

Prime Minister Narendra Modi accused Rahul Gandhi of targeting BJP MP Ravneet Singh Bittu with a ‘gaddar’ remark because of his Sikh identity while speaking in the Rajya Sabha.

Prime Minister Narendra Modi on Wednesday launched a sharp attack on Leader of the Opposition Rahul Gandhi, alleging that his “traitor” remark against BJP MP Ravneet Singh Bittu reflected the Congress party’s animosity towards the Sikh community.

The Prime Minister made the remarks in the Rajya Sabha while replying to the motion of thanks on the President’s address. Referring to an incident in the Parliament complex a day earlier, Modi said Gandhi’s comment had crossed all limits of political decency.

The controversy stems from a protest by suspended Opposition MPs, during which Ravneet Singh Bittu — a former Congress leader who joined the BJP ahead of the 2024 Lok Sabha elections — allegedly made a remark suggesting the protesters were behaving as if they had won a war.

In response, Rahul Gandhi was heard saying, “A traitor is walking by, look at his face,” before approaching Bittu and extending his hand. Gandhi then reportedly added, “Hello, brother. My traitor friend. Don’t worry, you will come back.”

Bittu refused to shake hands with the Congress leader and instead described him as an “enemy of the country” before walking away from the scene.

While the Congress later clarified that Gandhi’s remark was aimed at Bittu for leaving the party, the BJP seized upon the comment, calling it an insult to the Sikh community. Protests were subsequently held by members of the Sikh community outside the Congress headquarters and at other locations.

Addressing the House, Prime Minister Modi said that many leaders had quit the Congress in the past and that the party itself had split multiple times, but none of those leaders had been labelled a traitor. “He called this MP a traitor because he is Sikh,” the Prime Minister alleged, as treasury bench members raised slogans condemning the remark.

Manipur Assembly to meet at 4 pm today, floor test likely under new chief minister

The Manipur Legislative Assembly will convene at 4 pm today, with a floor test likely as the new chief minister seeks to prove his majority in the House.

The Manipur Legislative Assembly will convene at 4 pm on Thursday in Imphal, a day after Yumnam Khemchand Singh was sworn in as the chief minister. A floor test is likely to be held on the first day of the session to establish the majority of the newly formed government.

In the 60-member Assembly, the BJP holds 37 seats, while its ally National People’s Party has six members, giving the ruling combine a clear majority in the House.

Singh chaired the first Cabinet meeting of his government late Wednesday evening, shortly after taking oath as the 13th chief minister of Manipur. The meeting marked the formal start of administrative functioning under the new Council of Ministers.

His appointment came nearly a year after the resignation of former chief minister N Biren Singh, who stepped down following months of ethnic violence between the Meitei and Kuki communities in the state.

After taking oath, Singh thanked Prime Minister Narendra Modi and said he would work with “utmost diligence to advance development and prosperity in Manipur,” aligning the state’s efforts with the vision of Viksit Bharat.

He said the government’s focus would be on inclusive economic growth while preserving Manipur’s cultural heritage, adding that he would discharge his responsibilities with sincerity and dedication, mindful of the trust placed in him.

The summoning of the 12th Manipur Legislative Assembly by Governor Ajay Kumar Bhalla, along with the first Cabinet meeting, signals the resumption of legislative and administrative processes in the state, officially bringing President’s rule to an end.

The sixth session of the 12th Manipur Legislative Assembly was last held from July 31 to August 12, 2024.

PM Modi skips Lok Sabha reply as protests force repeated adjournments

PM Modi did not deliver his Lok Sabha reply today after sustained Opposition protests led to repeated adjournments over a dispute involving Rahul Gandhi’s proposed speech.

Prime Minister Narendra Modi did not deliver his scheduled reply to the Motion of Thanks on the President’s address in the Lok Sabha today after sustained Opposition protests led to multiple adjournments of the House.

The disruption followed an escalation of tensions linked to Congress leader Rahul Gandhi’s proposed speech and the suspension of eight Opposition MPs a day earlier. The situation worsened after remarks made by BJP MP Nishikant Dubey during the proceedings.

Dispute over references to books sparks fresh ruckus

The controversy intensified when Nishikant Dubey responded to Rahul Gandhi’s demand to speak on national security and references to the unpublished memoirs of former Army chief General MM Naravane. Dubey said that while Gandhi wanted to quote from an unpublished book, he himself had brought several books that, according to him, made claims about the Gandhi family.

As Dubey began listing these books and their contents, strong protests erupted from Opposition members. Krishna Prasad Tenneti, who was presiding over the House at the time, cited Rule 349, which restricts members from reading out books, newspapers, or letters unless directly related to parliamentary business. Despite repeated warnings, the matter remained unresolved, leading to another adjournment.

Rahul Gandhi accuses government of silencing debate

Earlier in the day, Rahul Gandhi alleged that he was being prevented from speaking on an issue of national importance. He claimed the government was uncomfortable with references to General Naravane’s memoirs, which he said discussed the handling of the 2020 China border crisis.

In a social media post, Gandhi said he intended to present the Prime Minister with a book authored by the former Army chief, adding that some cabinet ministers had even questioned the existence of the book. He also wrote to Lok Sabha Speaker Om Birla after the suspension of eight Opposition MPs, alleging that parliamentary debate was being curtailed.

After it became clear that the Prime Minister would not speak in the House today, Gandhi posted that PM Modi had avoided Parliament because he was “scared” to face the truth. Congress MP Priyanka Gandhi Vadra echoed the allegation, claiming the Prime Minister was unwilling to enter the House.

Proceedings disrupted throughout the day

Lok Sabha proceedings were first adjourned until 2 pm amid loud protests over the issue linked to Naravane’s memoirs. Even after the House reconvened, disruptions continued, preventing normal business from resuming.

Later, Congress MPs staged a demonstration outside the Parliament complex, demanding that Rahul Gandhi be allowed to speak on the President’s address.
