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.

Union Home Minister Amit Shah on Saturday praised Dharmendra Pradhan’s decision to step down as Union Education Minister, saying the move reflected the Bharatiya Janata Party’s commitment to placing the nation and students above any political position.

In a post on X, Shah said that for BJP workers, the country, its youth and students are more important than any office. He described Pradhan’s resignation as an example of the party’s guiding principle of prioritising national interest over personal ambition.

Shah highlights government’s focus on exam reforms

Amit Shah said the Narendra Modi-led government respects the sentiments of students and remains committed to strengthening the examination system following concerns over alleged paper leaks.

He said the Centre has introduced strict measures to ensure severe punishment for those involved in examination paper leaks and expressed confidence that these steps would deliver justice to students who cleared the National Eligibility-cum-Entrance Test (NEET).

Praises Pradhan’s work as Education Minister

Recalling Dharmendra Pradhan’s tenure, Shah highlighted several initiatives undertaken during his time in the Education Ministry. He credited Pradhan with helping implement the National Education Policy (NEP), expanding PM SHRI schools, promoting digital education, strengthening skill development and improving coordination between industry and academic institutions.

Shah also said Pradhan worked towards making examinations more inclusive and student-centric, adding that his tenure reflected his commitment to the vision of a developed India.

Resignation follows NEET controversy

Dharmendra Pradhan’s resignation comes amid nationwide protests over alleged irregularities in the NEET examination and growing demands for accountability.

The resignation has triggered political reactions across party lines. While opposition parties have described the development as a result of sustained student protests, BJP leaders have projected it as an example of accountability and commitment to national interest.

UP Government forms new SIT led by 3 IPS officers to probe Ayodhya Ram Temple donation theft

The Uttar Pradesh government has formed a new SIT led by three IPS officers to investigate the alleged Ram Temple donation theft case in Ayodhya following Supreme Court directions.

Ram Mandir

The Uttar Pradesh government has reconstituted a Special Investigation Team (SIT) headed by IG Kiran S, with DIG Somen Verma and SSP Dr Gaurav Grover as members, to investigate the alleged theft of donations meant for the Ram Temple in Ayodhya. 

The move comes after directions from the Supreme Court, which sought a reconstituted investigation team to ensure an independent and comprehensive probe into the allegations.

The newly formed SIT is expected to continue the investigation and submit a status report before the Supreme Court on July 27.

Senior IPS officers to lead the probe

According to the state government, the investigation will now be supervised by senior IPS officers.  The revamped SIT has been tasked with examining all aspects of the alleged embezzlement of temple donations and carrying the investigation forward.

The Supreme Court had observed that criminal investigations and technical examination of theft-related cases are more effectively handled by experienced police officers, leading to the reconstitution of the SIT under senior IPS leadership.

Probe to continue under court supervision

The case relates to the alleged embezzlement of offerings (chadhava) donated by devotees at the Shri Ram Janmabhoomi Temple in Ayodhya.

The Supreme Court is monitoring the investigation and will review the SIT’s status report at the next hearing.

Authorities are expected to continue examining evidence collected during the earlier stages of the investigation as the newly constituted SIT proceeds with the case.
