Abstract:

The present investigation entitled “Effect of High Temperature on Morpho-Physiological Attributes of Different Mustard (Brassica juncea L. Czern & Coss) Genotypes Under Late Sown Condition” was conducted in Randomized Block Design (RBD) with 12 new promising mustard genotypes viz., (Vardan, Ashirwad, NPJ-207, NPJ-208, RGN-403, PBR-417, DRMRIJ 16-3, DRMR-2035, RRN-911, RH-1556, RGN-368 and BPR 541-4) widely differing in their physiological maturity in two consecutive years (2017-18 and 2018-19) to envisage genotypic variability for morphological, physiological, yield, its attributes and correlation coefficient under late sown condition. Results revealed that almost all traits varied significantly due to genotypes during both years of study under late sown conditions. Findings disclosed that mustard genotypes viz., DRMRIJ 16-3, RGN-403, and RH-1556 recorded higher value of Plan height (cm), branches plant-1 i.e., primary, Secondary and tertiary branches and number of siliqua in different branches. Results also showed that, these traits possessed significantly positive correlation-ship with grain yield thereby indicates their involvement in process of heat tolerance mechanism under late sown conditions. These traits which are simple in measurement can be used as an index for assessing terminal heat tolerance in mustard genotypes under late sown condition. Based on overall relative performance it was concluded that mustard genotypes viz., DRMRIJ 16-3, RGN-403, RH-1556 and NPJ-208 were found to perform better with respect of seed yield and its other components as compared to other genotypes thereby proved to be more tolerant to terminal heat stress under late sown conditions.
