Abstract:
Sorghum is grown under rainy and post rainy (rabi) seasons. However, the grain sorghum raised during season has better grain and roti making quality which is preferred by the consumers. However, the yield level of rabi sorghum is low due to many factors such as environmental fluctuations, prone to diseases and long duration. At this context landraces will came into breeding rescue which represent heterogeneous, local adaptations of domesticated species, and thereby provide genetic resources that meet current and new challenges for farming in stressful environments. The present study stressed on the exploitation of hybrid vigour for productive related traits by using the landraces which are selected from the minicore collections for physical grain quality parameters, lodging resistance and stay greenness. Interestingly, out of 48 hybrids obtained by crossing 8 lines and 6 testers, 54.17% hybrids are lusturous, SPV-2333 x RSLG-23 is an outstanding hybrid having robust early vigour, superior grain quality, fodder yield and attractive physical grain quality parameters which is further advanced to isolate Trasngressive Seggrants.
