Drought tolerance, Groundnut, Yield, Genotypic variation

The cultivated Groundnut or peanut is an annual self pollinated legume crop. It is the major oilseed crop in India and in Andhra Pradesh. Drought is the single most factor limiting productivity under rainfed conditions. High temperatures associated with drought also affect many physiological processes in plant resulting poor yield. TCGS- 1399 recorded the highest pod yield (2164 kg/ha) and kernel yield (1493 kg/ha) by TCGS-1439. TCGS-1417 recorded maximum 100-pod weight (86.0 g) amd highest 100 kernel weight of 44.0 g. The highest sound mature kernel per cent of 91.0% was recorded by TGCS-1425. The same genotype TCGS 1425 recorded high drought tolerance in terms of high drought adaptive leaf traits under rainfed conditions viz., High SPAD Chlorophyll Meter Reading (SCMR), low Specific Leaf Area (SLA), high Relative Water Content (RWC), high total chlorophyll (chl.) content, high Chlorophyll Stability Index (CSI) and low Relative Injury (RI) per cent compared to Kadiri-6. These genotypes could be utilized in the breeding programme.
