Afficher plus [+] Moins [-]Sorghum is the third cereal crop after rice and wheat in India, mostly grownunder marginal and stress-prone areas of Semi-Arid Tropics (SAT). NARS,ICRISAT and private seed companies are the major stakeholders working forsorghum crop improvement in the last five decades (1960-2012). Altogethermore than 256 improved cultivars have been notified and made available tofarmers during the same time. The current knowledge about spread and impactof sorghum improved crop varieties in the country is incomplete. The presentstudy made an attempt to address these issues with help of primary as well assecondary sources of information. The analysis has concluded that nearly 80per cent of total sorghum area is under improved cultivars which helped toincrease the country productivity levels by 85 per cent during 1960 and 2010.This aptly proves that role of sorghum improved cultivars in sustaining thehigher yields
