Interspecific Hybridization between Mung Bean (Vigna radiata (L.) Wilczek) and Adzuki Bean (V. angularis (Willd.) Ohwi & Ohashi)1

Abstract Interspecific hybridization between Vigna radiata and V. angularis is reported for the first time. Two hybrids developed from embryos which were excised from immature seeds of V. radiata and cultured on artificial medium. The plants flowered early and continuously until death. No seeds were produced. Mean pairing at metaphase I was 2.39 II + 17.22 I (2n = 22).
