Abstract:

Fifteen chilli genotypes were screened for temperature resilience during summer season in of 2017-18. The genotypes were subjected to two temperature levels, i.e. optimum temperature (inside the growth chamber) and summer temperature (in open field condition). The characters like plant height, fruit length, fruit weight, pedicel length, number of seeds per fruit, rate of photosynthesis, chlorophyll, pollen fertility, pollen viability and fruit set per cent were decreased and leaf proline, leaf phenol and ascorbic acid were increased under high temperature stress. However, variable response was observed for the traits oleoresin and capsaicin content depending upon the genotypes under temperature stress condition. Genotypes LCA-960, UARChH-42 and 9608U were found more temperature resilient in chilli. The genotype PBC-80 registered highly sensitive to temperature stress condition. Phenotypic coefficient of variation was more than genotypic coefficient of variation for all the characters studied. High heritability coupled with high genetic advance in per cent of mean was observed for characters like plant height, fruit length, fruit weight, pedicel length, number of seeds per fruit, rate of photosynthesis, chlorophyll, leaf proline, leaf phenol, ascorbic acid, oleoresin, capsaicin, pollen fertility, pollen viability and fruit set per cent.
