Scope for utilization of native specialty landraces, cultivars and basmati types in rice heterosis breeding

  Traditional landraces and basmati lines are useful pool of important traits and need to be analyzed for hybrid breeding utilization in rice. Furthermore, released cultivars have good agronomic characters which can be used directly in the hybrid breeding program. A study was conducted on 80 landraces, 5 basmati lines and 36 cultivars to characterize them, for fertility restoration traits and identification of...

Analysing and modeling the relationship between yield and yield components in sunflower under different planting dates

  The relationships between planting dates and yield and it's components in sunflower was evaluated through orthogonal polynomial regression analysis. Five field experiments were conducted during the summer season of 2011 to study the effect of five planting dates and three oilseed sunflower genotypes and their interactions on yield and yield components of sunflower. The highest seed yield, oil yield, plant...
