Canopy and reproductive development in mungbean (

Context Mungbean (Vigna radiata (L.) Wilczek) is an important grain legume for food, feed, and green manure. yield highly variable due to fluctuating temperature unpredictable rainfall. Aims To improve stability, it critical utilise a model that can simulate mungbean phenology, biomass, accurately. Methods A thorough understanding of the physiological determinants growth required advance existing crop modelling capability. Currently, there limited canopy reproductive development their variation in germplasm. Two experiments (controlled field environments) were conducted at Gatton, Queensland, 2018–19. Six Australian genotypes one black gram mungo L.) grown under non-limiting conditions. Plant phenotypic traits (canopy development, time first, 50% flowering, duration flowering podding, flower appearance, pod addition rates) recorded. Key results Genotypes M10403 Satin II had significantly higher leaf appearance rate (LAR). with greater LAR number leaves but lower individual area. varied first Onyx-AU (black gram) Celera II-AU earliest. Flowering podding rates, these phenological phases among genotypes. Total plant area (TPLA) approached its maximum mid-podding stage. Implications This study quantified key relationships associated improvement accurately inform possible constraints are limiting productivity.
