"Large genetic variation for heat tolerance\r\nin the reference collection of chickpea\r\n(Cicer arietinum L.) germplasm"^^ . "Chickpea is the third most important pulse crop worldwide. Changes in cropping system\r\nthat necessitate late planting, scope for expansion in rice fallows and the global warming\r\nare pushing chickpeas to relatively warmer growing environment. Such changes demand\r\nidentification of varieties resilient to warmer temperature. Therefore, the reference collection\r\nof chickpea germplasm, defined based on molecular characterization of global composite\r\ncollection, was screened for high temperature tolerance at two locations in India (Patancheru\r\nand Kanpur) by delayed sowing and synchronizing the reproductive phase of the crop with\r\nthe occurrence of higher temperatures ($358C). A heat tolerance index (HTI) was calculated\r\nusing a multiple regression approach where grain yield under heat stress is considered as\r\na function of yield potential and time to 50% flowering. There were large and significant\r\nvariations for HTI, phenology, yield and yield components at both the locations. There\r\nwere highly significant genotypic effects and equally significant G £ E interactions for all the\r\ntraits studied. A cluster analysis of the HTI of the two locations yielded five cluster groups\r\nas stable tolerant (n ¼ 18), tolerant only at Patancheru (n ¼ 34), tolerant only at Kanpur\r\n(n ¼ 23), moderately tolerant (n ¼ 120) and stable sensitive (n ¼ 82). The pod number per\r\nplant and the harvest index explained $60% of the variation in seed yield and $49% of\r\nHTI at Kanpur and $80% of the seed yield and $35% of HTI at Patancheru, indicating that\r\npartitioning as a consequence of poor pod set is the most affected trait under heat stress.\r\nA large number of heat-tolerant genotypes also happened to be drought tolerant."^^ .
