| Abstract |
The aims of this research work were to investigate the effects of terminal drought (TD) on growth, pod yield and harvest index and to identify the high potential of pod yield (PP) genotypes and low reduction of pod yield (RP) genotypes. A 2 × 10 factorial in RCBD was undertaken in a greenhouse with four replications at Khon Kaen University (KKU), Thailand, from February to May 2018 and 2019. Factor A included two water regimes, field capacity (FC) and 1/3 available water (1/3 AW) at 60 days after planting (DAP) until harvest. Factor B included 10 Valencia peanut genotypes. The data were recorded of total biomass, shoot dry weight, pod dry weight and harvest index (HI). Under TD conditions, total biomass, shoot and pod dry weight and HI were reduced. The pod yield under TD was contributed by the larger portion of the RP whereas the PP (at FC.) contributed a smaller portion. From the two year results, the low RP genotypes were PI365564, and ICG8517, whereas the high PP genotypes were ICG10092, and ICG10890. The distinct groups with high PP and low RP could be selected as parental lines and generated progenies in varietal improvement program aiming to develop peanut varieties with high PP and low RP under TD. |
