The wheat varieties DBW187 and DBW222 have been found superior over HD-3086 as far as heat tolerance is concerned. During the crop season 2021-22, the varieties namely DBW187 and DBW222have shown heat tolerance with yield gain of 3.6% and 5.4%, respectively as compared to HD-3086 (Source: AICRP on Wheat and Barley progress report, 2020-21 & 2021-22).

The variety PBW 803 developed by the Punjab Agricultural University (PAU), Ludhiana is suitable for irrigated timely sown condition and resistant to brown rust as well as moderately resistant to stripe rust. This variety is not recommended as heat-tolerant variety.

The Government aims to promote the use of heat-resistant varieties amongst the farmers through public and private partnership and providing seed directly to the farmers. To promote the use of these varieties, the Indian Institute of Wheat and Barely Research (IIWBR), Karnal under ICAR has signed 250 Memorandum of Agreements (MoAs) for DBW 187 and 191 MoAs for DBW 222 with private companies for seed production. The institute has distributed more than 2500 quintal seeds of DBW 187 and 1,250 quintal seeds of DBW 222 during the crop season, 2021-22.

The ICAR-IIWBR Karnal has initiated a specific research project entitled “Breeding high yielding wheat genotypes for stress conditions of warmer regions of India” on heat tolerant varieties. Besides, ICAR-IIWBR Karnal is also collaborating with International Maize and Wheat Improvement Centre (CIMMYT), Mexico on development of climate resilient wheat varieties.

This information was given by the Union Minister of Agriculture & Farmers Welfare Shri Narendra Singh Tomar in a written reply in Rajya Sabha today.
