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.

Telangana Chief Minister Revanth Reddy’s remarks comparing the Gandhi Parivar and Sangh Parivar have triggered a political exchange, with the BJP hitting back at the Congress leader.

Speaking in Kerala on Friday, Mr Reddy described the contest over India’s future as a fight between the two “parivars”. He said the Gandhi family had made sacrifices for the country while accusing the Sangh Parivar of attempting to divide India on the basis of religion, caste, region and language.

What Revanth Reddy said

Mr Reddy cited Mahatma Gandhi, Indira Gandhi and Rajiv Gandhi while speaking about what he described as sacrifices made by the Gandhi family.

He also referred to Sonia Gandhi, Rahul Gandhi and Priyanka Gandhi, saying they had given up positions, power and high office.

The Telangana Chief Minister said he had no remaining personal political ambitions and described his objective as working towards a Congress-led government at the Centre with Rahul Gandhi as Prime Minister.

Mr Reddy also appealed to people to stand with the Gandhi Parivar and oppose the Sangh Parivar. He described the latter as a threat to India’s democracy.

BJP hits back

The BJP responded to Mr Reddy’s remarks on Saturday.

BJP spokesperson Pradeep Bhandari said the Telangana Chief Minister’s comments amounted to an admission that Congress’s objective was to bring the Gandhi family back to power.

He also linked Mr Reddy’s remarks to the ongoing political debate around “vote chori”, the Election Commission, the Constitution and democracy, arguing that the Congress’s focus was instead on the Gandhi family.

The exchange adds to the political confrontation between the BJP and Congress, with Mr Reddy presenting the Gandhi Parivar and Sangh Parivar as opposing forces in India’s political future, while the BJP has interpreted his remarks as evidence of Congress’s focus on the Gandhi family.

Tamil Nadu Chief Minister and Tamilaga Vettri Kazhagam (TVK) president C Joseph Vijay has questioned DMK president MK Stalin over the handling of the POCSO case involving Gem Granites founder R Veeramani. The political exchange follows renewed investigation into allegations involving minor girls.

Vijay’s remarks came as the ruling TVK stepped up its questions about how the case was handled during the previous DMK government. The party’s IT wing has alleged that the earlier investigation was weakened and questioned why a final report was filed.

The allegations have been rejected by the DMK. Stalin has said that no order was issued by the DMK government to protect anyone in the case and has called the allegations false and defamatory.

What did Vijay say about the Veeramani case?

Vijay questioned Stalin over the handling of the case and demanded an explanation from the former chief minister.

The TVK has specifically questioned why action was not taken against Veeramani during the previous administration and why the earlier investigation resulted in a closure report.

The party has also raised questions about the role of officials involved in the earlier investigation. These are political allegations made by the TVK and have not been established as facts.

What is the Veeramani POCSO case?

The case concerns allegations of sexual abuse of minors involving R Veeramani, the founder of Gem Granites.

The case came under renewed scrutiny after a special POCSO court rejected an earlier closure report and ordered further investigation. The expanded probe has subsequently identified additional alleged survivors who were minors at the time of the alleged offences, according to current reporting.

The investigation is also examining the circumstances surrounding the earlier probe and whether there were any lapses in how the case was handled.

What has MK Stalin said?

Stalin has rejected allegations that the previous DMK government protected Veeramani.

He has said that no order was issued by the DMK government to shield anyone in the case. Stalin has also said that everyone responsible for the alleged offences, including anyone who aided or attempted to protect the accused, should face the law.

The DMK president has further said that the focus should remain on securing justice for the affected girls rather than making political allegations.

Why has the case become a political issue?

The Veeramani case has become the subject of a political dispute between the ruling TVK and the DMK over the handling of the earlier investigation.

The TVK is questioning the previous government’s handling of the case, while the DMK has denied that it intervened to protect the accused.

At this stage, claims about political interference or deliberate weakening of the earlier investigation should be treated as allegations unless established by the ongoing investigation or judicial proceedings.
