"Combination of empirical and trait-based approaches for breeding drought tolerance in\r\ngroundnut (Arachis hypogaea L.)"^^ . "Breeding groundnut varieties that combine improved pod yield\r\nunder water-deficit stress, and enhanced water use efficiency\r\n(WUE) is an important strategy to overcome the challenges\r\nin water-limited conditions. SPAD chlorophyll meter reading\r\n(SCMR) and specific leaf area (SLA) are the two important traits\r\nassociated with WUE. SCMR is simple, non-destructive and robust\r\nmethod. Maintaining high chlorophyll density under water\r\nstress conditions is associated with high WUE in groundnut, and\r\nSCMR measures green colour intensity associated with chlorophyll\r\ndensity. A RIL population (280) was evaluated during\r\n2015/16 under well-watered (WW) and water-deficit stress\r\n(WS) for yield parameters and SCMR. Pod yield is independent\r\nof SCMR (R2=0.003), suggesting the importance of simultaneous\r\nselection for both these traits in breeding programs. For\r\nbreeding varieties suitable for water-stress conditions, measuring\r\nboth pod yield under stress and WUE through its surrogate\r\nSCMR are useful. In Africa and Asia, groundnut is largely\r\na rainfed crop. The frequency of drought is variable, and every\r\nyear is not a drought year. Therefore, the commercial groundnut\r\nvarieties should perform well under normal rainfall years,\r\nand have less yield penalty during drought years. The approach\r\nof measuring pod yield penalty under water-deficit stress compared\r\nto WW condition is a useful selection criterion in breeding\r\nprograms, wherein the lines with minimum yield penalty are\r\nselected. Such a selection criteria enable selection of genotypes\r\nthat perform well under normal seasons and have less yield penalty\r\nduring drought seasons. In this paper, we discuss progress\r\nin groundnut breeding at ICRISAT using these two approaches."^^ . "2017-02" . . . . . . . . . . . . . . "P"^^ . "Janila"^^ . "P Janila"^^ . . "S S"^^ .
