PAU develops country’s first Bt cotton varieties

Punjab Agricultural University in Ludhiana has said that it has developed country's first genetically-modified (Bt) varieties of cotton — the seeds of which could be reused by farmers, resulting in saving the repeated cost they have to bear every season.

“Indian Council of Agricultural Research (ICAR) has identified three Bt cotton varieties — namely PAU Bt 1, F1861 and RS 2013 — for cultivation in states of Punjab, Haryana and Rajasthan. They (ICAR) have asked us to put up the proposal regarding releasing of these varieties,” PAU vice-chancellor Dr Baldev Singh Dhillon told The Hindu.

Dr. Dhillon said that the notification regarding these varieties could be out by as early as next month after ICAR's scheduled meeting. Meanwhile, the process for multiplying the seeds would be started. “We are expecting that by next year we will be able to distribute few seeds to farmers for sowing in fields. Surely, by next to next year we will distribute seeds on large scale,” he said.

“PAU Bt 1 and F 1861 were developed by PAU, whereas, RS 2013 was developed at Rajasthan Agricultural University (RAU), Bikaner. While the PAU Bt 1 was completely developed at Punjab Agricultural University, the F 1861 and RS 2013 varieties were converted to Bt version by Central Institute for Cotton Research (CICR), Nagpur. All the three varieties carry ''cry1Ac'' gene imparting resistance against bollworm complex,” said an official PAU statement.

Dr. Dhillon said with the cultivation of these varieties, the cotton farmers will not have to purchase the costly Bt cotton hybrid seed every year. “The farmers can keep their own harvest for next sowing season. Bt cotton hybrids became popular due to ‘Bt technology’ which imparts resistance to bollworms, which are a major cause of yield loss in cotton,” he said, adding that with the adoption of these new Bt varieties by the farmers, a major shift is likely to take place in cotton cultivation in northern states.

Notably, cotton is the only genetically-modified seed that’s legally allowed in India. Punjab alone needs around 20-25 lakh packets of Bt cotton seed for sowing of crop which roughly amounts to around Rs. 225 crores.

“The price of seed of these Bt cotton varieties shall much lower as compared to current market price of Bt cotton hybrids seed, and thus, there is a scope to reduce the cost of cultivation and increase the savings of the farmers,” he added.
