Type: article
Abstract: Rice is an important crop grown worldwide. The present study aimed to investigate the tolerant varieties under saline and non-saline field conditions and determine the genetic variability among the hybrids for morphological traits. The results showed that the mean square of analysis of variance for different morphological parameters under saline and controlled conditions indicated that genotypes, treatments, and interactions were significant at P<0.01 and 0.05 probability levels for various traits. Taller rice plant was observed by the parent RST-178 in both saline and non-saline conditions (98.67 and 96.80 cm). Tillers plant-1 was more in both saline and normal conditions than the parent Shua-92 (19.06 and 13.06). Kharaganija and HHZ-SAL-10DT1DT1 observed to have more tillers, panicle length and grains panicle-1 more under saline conditions. Grain yield per plant-1 was found greater in the parent KSK-133 and GML-498 (16.53 g). HHZ-SAL-10DT1DT1 observed maximum relative decrease for plant height, tillers plant-1, panicle length and biological yield plant-1. RST-178and GML-498 also showed greater decline for panicle length, number of grains, grain yield plant-1 and biological yield plant-1. HHZ-SAL-10 DTI DT1 x Kharaganija minimum plant height, more tillers, number of grains panicle-1, seed index, biological yield plant-1 and grain yield plant-1in both saline and non-saline field. HHZ-SAL-10DTI DT1 x GML-498 observed maximum panicle length. Kharaganija and HHZ-SAL-10DT1DT1 can be recommended as salt tolerant varieties. Shua-92 observed to have high yield and performed best in normal and saline environment. The hybrid HHZ-SAL-10 DTI DT1 x Kharaganija followed by HHZ-SAL-10DTI DT1 x GML-498 and GML-498 x Shua-92 showed minimum plant height, more tillers, number of grains panicle-1, seed index, biological yield plant-1 and grain yield plant-1 in both saline and non-saline field and these are efficient crosses as per findings.
