This research aimed to analyze the inheritance and variability of morpho-economic traits in parental lines and their F₁ and F₂ populations in mung bean (V. radiata syn. P. aureus L.). Specifically, these traits are main stem length, pods per plant, pod length, seeds per pod, and 1000-seed weight. The experiment commenced at the experimental field of Chirchik State Pedagogical University, Uzbekistan, using several mung bean’s parental genotypes and their F₁ and F₂ populations. In F₁ and F₂ populations, the inheritance of main stem length primarily exhibited positive overdominance, as well as positive and negative intermediate inheritance. The pods per plant predominantly revealed overdominance, with occasional positive intermediate and negative overdominance. Pod length consistently displayed positive intermediate inheritance across all hybrids, while the seeds per pod and 1000-seed weight demonstrated instances of both positive and negative overdominance. In F₂ populations, the heritability ranges for various traits were for main stem length (53.0%–97.0%), pods per plant (66.0%–83.0%), pod length (11.0%–44.0%), seeds per pod (22.0%–66.0%), and 1000-seed weight (77.0%–89.6%). Isolation of the recombinant forms with heterotic effects occurred in F₂ populations for the above traits. The utilization of these recombinants as source material will offer significant efficacy in mung bean breeding programs.

Key findings: The pods per plant predominantly detailed overdominance, with occasional instances of positive intermediate and negative overdominance in mung bean (V. radiata syn. P. aureus L.). Pod length consistently displayed positive intermediate inheritance, while the seeds per pod and 1000-seed weight exhibited instances of both positive and negative overdominance across all hybrids.
