• Stay-green trait, early ground cover, chlorophyll retention at later stages are contributing greatly to tolerance under moisture stress.
Brown top millet
• Wide variability was obderved among 32 germplasm lines of brown top millet
- • Variations in quality traits, protein content (8.31-16.06 %), starch content (46.43-97.25%) and amylase content (1.49-21.91 %) was observed in association mapping panel.

- • Phenotyping kharif sorghum genotypes (inbreds, hybrids, and parents) for physiological basis of genetic gain in yield potential indicated that older cultivars SPV 462 and CSV 20 maintain higher LAI and LAD than others. LAI & LAD has showed significant positive relationship with SLA, total biomass, while its relationship with SLW was negative.
• Specific leaf weight (SLW) at flowering had shown significant positive relationship (P≤0.05) with biomass, grains/m2 and grain yield.
• High biomass GS3, LAD and sink number needs to be incorporated in new parental lines for enhancing yield potential.
• Per day grain productivity, biomass in GS3 stage, SLW, LAD and HI are the simple criteria to select higher yielding kharif sorghum genotypes from segregating populations.
• The highest mean starch content of 66.46 g 100g−1 was observed in kodo millet, while lowest starch content of 58.9 g 100g−1 was found in barnyard millet.
• The mean fat contents of kodo and proso millet were lower and foxtail millet was noted as higher than other small millets investigated.
• Foxtail millet has higher zinc content and lower in Kodo millet. Barnyard millet shows higher content of calcium and lower is noted in Proso millet. Little millet shows higher concentration of magnesium while barnyard millet shows low concentration of magnesium.
• keeping ragi pizza base at room temperature for 3 days and for 6 days at chilling temperature was found safe for consumption
• A non-dairy plant-based yoghurt which was lactose free was developed from sorghum and soya milk.
• The demonstrated Kharifsorghum cultivars gave 62% more grain yield and 39% stover yield over the local check across the locations. The demonstrated cultivars gave net returns of Rs. 41,240/- per ha on the cost of Rs. 21,093/- per ha, which is 72% higher than to the local checks (Rs. 23,986/- per ha).
• The demonstrated rabi sorghum varieties gave 48% higher grain and 42% fodder yields than the local checks. On an average, the demonstrated varieties could earn net returns of Rs. 43,029/- on the cost of Rs. 23,010/- per ha, which is 61% higher than the local checks.
• Several training and workshops were organized by the Institute for the benefit of various stakeholders from across the country including digital field book, statistical data analysis, students research.
