| Abstract |
Drought at different growth stages has different effects on peanut (Arachis hypogaea L.). Terminal drought greatly affects reproductive traits and consequently reduce pod yield. The objective of this study was to determine the reproductive efficiency responses and yield of Valencia peanut genotypes under terminal drought conditions. A 2×9 factorial experiment consisting of nine peanut genotypes and two water regimes (full irrigation and drought stress) was used, and the treatments were arranged in a randomized complete block design with four replications at the field crop research station of Khon Kaen University during July to October 2016. Based on flower number and number of reproductive parts, the data were recorded for the number of pegs (reproductive sink number = hanging pegs + total pods) and number of total pods (immature and mature pods plant-1) at harvest. Traits related to reproductive efficiency including percentage of flower to peg, percentage of peg to pod, percentage of pod to mature pod and percentage of flower to mature pod were recorded at harvest. All Valencia genotypes had produced flowers under drought stress conditions, but they had low conversion of flowers to economic yield. Valencia peanut genotypes have different number of reproductive traits and yield. Genotypes with high reproductive efficiency responses (RET1, RET2 and RET4) also showed high yield. Genotypes ICG 14127 and ICG 10092 performed well under drought conditions.
