Himachal Pradesh Krishi Vishvavidyalaya develops two blast disease-resistant paddy varieties

Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya, Palampur, has developed two new high-yielding and blast disease-resistant varieties of paddy. This significant achievement was shared by the Vice-Chancellor of the university, Prof Naveen Kumar, who lauded the efforts of the scientists at the Paddy and Wheat Research Centre, Malan, recently.

“These varieties are not only based on advanced agricultural technology but are also tailored to meet the practical needs of farmers,” said Prof Kumar. He emphasised that new strains would contribute to the food security of the state and play a crucial role in boosting farmers’ incomes by reducing losses caused by blast disease, a major threat to paddy crops in Himachal Pradesh.

Blast disease, caused by the Magnaporthegrisea fungus, severely affects the leaves, stems and panicles of paddy plants, leading to significant yield reduction. With paddy being the principal crop in ten districts of Himachal Pradesh, combating this disease has been a longstanding challenge for the agricultural community.

The newly-developed varieties — Him Palam Dhan-3 (HPR-2865) and Him Palam Dhan-4 (HPR-3201) — have been officially approved by both state and national varietal release committees for cultivation in the hilly regions of Himachal Pradesh and Uttarakhand.

Him Palam Dhan-3 is a medium-height variety with long, thick grains and an average yield of 38-40 quintals per hectare. Him Palam Dhan-4, also of medium height, produces long, slender grains akin to Basmati, with an average yield of 40-42 quintals per hectare. Both varieties mature within 120-130 days, making them suitable for local climatic conditions.

“These paddy varieties are the result of years of rigorous scientific research, continuous field trials and active farmer participation. Their standout features include blast disease resistance, high-yield potential, shorter maturity duration and market-friendly grain quality,” the VC said.

Prof Kumar added that the reduction in the need for chemical treatments due to disease resistance will not only reduce input costs for farmers but also support more sustainable and eco-friendly farming practices in the region.
