Abstract:
The present research work was conducted at Crop Research Farm, Nawabganj and Seed Multiplication Farm Bojha, Chandra Sheker Azad University of Agriculture and Technology, Kanpur (U.P.) India at high and normal salt stress soil condition to study Correlation coefficients analyses during kharif 2018 and 2019 among the 100 rice genotypes including six standards (checks) varieties viz., CSR10, CSR36, CSR43, Usar Dhan 3 for salinity and alkalinity tolerant, while IR64 and PUSA 44 as salt stress sensitive were grown in Augmented Randomized Block Design as parents for developing new rice varieties to break the yield barrier under sodic land. The correlation analysis revealed that all the traits such as day to 50% flowering, Days to maturity, Plant height, Panicle bearing tillers/plant, Panicle length, Spikelets /panicle, Grains/panicle, Spikelet fertility, Biological yield/plant, Grain yield/ plant, Harvest index, Stress score at reproductive phase and 1000-grain weight have the positive contribution to grain yield except Stress score at vegetative stage under pooled environment of alkalinity condition. The genotypes IL 773 followed by IL444, IL 105, IL 277, IL 891, IL 125, IL 344, IL 1121 and IL655 64 were found to be the promising genotypes for yield and yield contributing traits.
