Abstract:

The present research work was conducted at high and normal salt stress soil condition to study the inherent genetic variation existing among the 78 accessions including seven standards (checks) varieties viz., CSR36, CSR10 , CST7-1, CSR27, Usar Dhan 3 for salinity and alkalinity tolerant, while Sambha Sub1 as for general stress, 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. Grain yield showed highly significant and positive association ship with filled grains panicle-1 followed by spikelet fertility, plant height, and test weight can be used as selection criteria for yield improvement under high stress environment. Principal Component Analysis revealed that first three principal components addressed 80.038 (%) of the total variability which was represented by the first five principal components. CARI Dhan 11, CSRC(S) 47-7-B-B-1-1, IR52280-117-1-1-3, CSR 2016-IR18-10, CSA 2016-IR18-6 6 had high Principal Factor score in factor 1 indicated that they had high variation for spikelet fertility (%). Similarly, Principal Factor score for NDRK 11-24, KR15006, NDRK 11-21, CSR36 ©, Usar Dhan 3 © were showed high variation in factor 2 which representing the productive tillers plant-1, 1000 seed weight.
