Ten pearl millet genotypes selected on the basis of response to supra-optimal temperature tolerance were crossed in a half-diallel mating system.
The 45 F 1 hybrids produced were tested along with parents for heat tolerance and related traits at seedling stage.
Field screening and laboratory screening techniques were simultaneously used for the evaluation of F 1 hybrids and their parents.
Heat tolerance was measured as seedling thermotolerance index (STI) and seed to seedling thermotolerance index (SSTI) under field conditions, but membrane thermostability (MTS) in the laboratory.
The hybrid H77/29-2 × CVJ-2-5-3-1-3 showed highest STI value followed by H77/833-2 × 96AC-93.
The genotype H77/833-2 × 96AC-93 had the highest worth for SSTI.
These three indices were highly correlated among themselves.
STI values were invariably high, whereas SSTI has lower values, as it also covers the effect of under soil mortality (USM).
It was seen that the heat tolerance indices STI and SSTI were not showing any perceptible pooled correlation with developmental traits except germination and emergence rate.
Based on our results, it could be suggested that membrane thermostability (MTS) may be used for screening large number of genotypes.
Field based indices STI and SSTI may be used for evaluation of hybrids and varieties before they are released.
