Development and interaction between plant architecture and yield-related traits in winged bean ( Psophocarpus tetragonolobus (L.) DC.)

摘要: Winged bean (P. tetragonolobus (L.) DC.) is a leguminous crop that could contribute towards food security in tropical areas, but whose growth and development still poorly understood. In order to develop improved individuals for increased green pod seed productivity, we investigated the factors involved winged plant architecture, development, their link number of yield-related traits. An F2 population was generated from cross between M3 FP15 Malaysian accessions assessed under field conditions Malaysia. The results showed stem length be mainly influenced by internode (rs = .80; p < .01), while multiple genes controlling branches, with an average branches offspring above highest parent value. appeared influence most final pods per (rs = .44; p < .001), flowering potentially transgressive segregation earliness, without preventing potential high pod-yielding (rs = − 208; p   = .056). Taken together, reported here shed light on interaction morphological, developmental, traits, defining targets developing ideotypes direct breeding programmes this underutilised crop.
