Background: Heat stress is a major restrain in chickpea (Cicer arietinum L.) productivity. Developing tolerant chickpea genotypes contributes breeding materials for hybridization programme. Stress indices related to abiotic stresses are found effective in screening of genotypes for high temperature tolerance in chickpea. Methods: An experiment with 24 genotypes under two different environments i.e., timely and late sown conditions was planned to identify the chickpea genotypes tolerant to heat stress, using thirteen stress indices. Stress Susceptibility Index (SSI) is the cardinal index to group genotypes based on their tolerance level. Stress indices Mean Productivity (MP), Geometric Mean Productivity (GMP), Harmonic Mean (HM) Index, Heat Resistant Index (HRI) and Modified Heat Tolerance Index (MHTI) are very effective in identifying stress tolerant genotypes. Result: The result indicated that genotypes H 04-75, H 08-75, H 12-26, H 09-96, ICCV 92944, DCP 92-3 and GNG 2226 are tolerant to heat stress. The identified genotypes can be used as parents in hybridization programme for breeding chickpea cultivars tolerant to high temperature environments.

Membrane Thermostability

Heat stress limits the growth, development, and yield of crop plants when it occurs during short or long periods of time. An experiment was conducted with the objectives of (i) evaluating the cell membrane thermostability (CMT) as an indicator of heat tolerance in sugarcane and to determine its relationship with physiological parameters under heat-stressed conditions, and (ii) evaluating the utility of CMT for selecting heat-tolerant genotypes in a breeding program. A total of nine elite experimental, and four commercial sugarcane genotypes were evaluated for CMT, and the results are expressed as relative cell injury (RCI). Six genotypes were classified as highly tolerant and seven as highly sensitive. We concluded that the use of RCI, as an indicator of CMT in sugarcane genotypes, is a suitable useful parameter for selecting the genotypes tolerant to heat stress in a breeding program. This procedure, combined with other characters, helps to identify sugarcane plants with the ability to maintain a high yield photosynthetic rate under stressful field conditions. Furthermore, it offers an opportunity to improve selection efficiency over that of field testing, since high temperature stresses do not occur consistently under field conditions.
