Abstract:
In order to study correlation coefficients analyses among 100 rice genotypes, including six standards (checks) varieties-CSR10, CSR36, CSR43, and Usar Dhan 3-for salinity and alkalinity tolerant soil conditions, the current research was carried out at Crop Research Farm, Nawabganj, and Seed Multiplication Farm Bojha, Chandra Sheker Azad University of Agriculture and Technology, Kanpur (U.P.), India. Meanwhile, IR64 and PUSA 44, which are sensitive to salt stress, were grown in expanded randomised block design as parents for developing new rice varieties to overcome the yield barrier under sodic land. The correlation study showed that every characteristic, including days to 50% flowering, days to maturity, height of the plant, number of tillers per plant, length of the plant, number of spikelets per panicle, number of grains per panicle, and fertility of the spikelets, With the exception of the stress score during the vegetative stage in a pooled environment with alkalinity conditions, biological yield/plant, grain yield/plant, harvest index, stress score during the reproductive phase, and 1000-grain weight all positively contribute to grain yield. In terms of yield and features that contribute to yield, the genotypes IL 773, IL444, IL 105, IL 277, IL 891, IL 125, IL 344, IL 1121, and IL655 64 were determined to be the most promising.
