Breeding for Pest and Disease Tolerance High Yielding Variety (DHLM-36-3-1) in Little Millet (Panicum sumetrense. L)

Developed from 2008 to 2013 and evaluated between 2010 and 2014, the high-yielding medium-maturing little millet variety DHLM-36-3-1 was officially released and notified in 2018, showing its potential as an excellent variety. This cultivar, developed at the Agricultural Research Station in Hanumanamatti, University of Agricultural Sciences, Dharwad, is well-suited to the state of Karnataka. It matures in 85 to 90 days and features an erect growth habit, reaching heights of 112 to 130 cm, with bold, oval-shaped grains of light black color. DHLM-36-3-1 demonstrated a grain yield of 14.29 q/ha and a fodder yield of 5.6 t/ha, showing good tolerance to shoot fly infestation (15.50%) compared with the national check JK-8, which recorded a 20.34% infestation rate. Furthermore, DHLM-36-3-1 outperformed both national checks OLM-203 and JK-8 by 9.59% and 11.21%, respectively, in terms of grain yield. Similarly, the newly developed variety DHLM-14-1 has yielded promising results across various trials conducted throughout India, demonstrating its potential as a high-yielding and nutritionally rich option for farmers. Over three growing seasons, DHLM-14-1 achieved an impressive average seed yield of 35.12 q/ha, exceeding the local check TNAU-63 by 18.56% and the national check OLM-203 by 12.06%. It has consistently performed well in All India Coordinated Trials, showing adaptability across diverse agro-climatic conditions, with notable yield improvements in states such as Andhra Pradesh, Jharkhand, and Tamil Nadu. Nutritional assessments highlight DHLM-14-1's superior mineral profile, boasting higher levels of zinc (4.06 mg/100 g) and calcium (3.45 mg/100 g) compared to national checks, while its iron content (16.2 mg/100 g) significantly surpasses that of OLM-203. Additionally, disease resistance evaluations revealed that DHLM-14-1 maintained lower incidence rates for grain smut and brown spots, with competitive resistance to shoot fly. Collectively, these findings emphasize DHLM-14-1's vital role in promoting sustainable millet production, enhancing food security and farmer livelihoods, supporting integrated pest management strategies, and improving the nutritional quality of staple diets in areas with micronutrient deficiencies.
