A New Mungbean Cultivar, ‘Samhwang’, with Yellow Seed Coat and Lobed Leaflets

Abstract

A new mung bean cultivar, Vigna radiata (L.) R. Wilczek 'Samhwang', was derived from a cross between 'Samgang' and 'KM9901-3B-15-2-4' obtained in 2006 and developed at the Jeollanamdo Agricultural Research and Extension Services (JARES) in 2014. 'Samhwang' has an erect growth habit, lobed leaflets, green hypocotyls, light yellow corolla, and a dull yellow seed surface. Its stem length was 64 cm, 5 cm shorter than that of the control cultivar 'Owool'. The 1000-seed weight was 53 g, i.e., 4 g heavier than that of 'Owool'. 'Samhwang' exhibited similar field resistance to mung bean mottle virus, cercospora leaf spot, powdery mildew, and lodging when compared with that of the control cultivar. The sprout yield ratio and hard seed rate were the same as those of 'Owool'. The average seed yield of 'Samhwang' was 1.76 ton/ha, which was 14% greater than that of 'Owool' (Registration No. 5877).

Adaptability and stability of mungbean genotypes in the Mid-North of Mato Grosso, Brazil

“…The mass of 100 grains differed among genotypes (P < 0.01) in all eight environments (Table 2), ranging from 4.98 g (Sorriso2020NF) to 6.38 g (Sinop2019WF). On average, grains of the evaluated genotypes were within the standard of commercial cultivars (Vieira et al, 2002;Vieira et al, 2008;Khattak et al, 2021;Kim et al, 2020;). Regarding the VC scores, there were significant differences (P < 0.05) among the tested genotypes in Sinop2020WF and in all four Sorriso environments (Table 2).…”

“…The market for green seed coat grains is most common for mungbean. However, yellow seed coat cultivars have been selected for regions with a preference for this grain color (Biswas et al, 2016;Kim et al, 2019;Kim et al, 2020). Exception for G9, the VC scores of the genotypes were equal to or greater than three (Table 4), which corresponds to most of the traits suitable for commercial cultivation.…”
