Agronomic Characteristics and Seed Yield of Indonesian Mungbean (Vigna radiata) Genetic Resources

Abstract

The availability of mungbean (Vigna radiata) genetic resources is important in breeding programs for development of new improved varieties. The objective of this study was to describe the characters of 300 accessions of ILETRI’s mungbean genetic resources collections. The study was conducted in Jambegede Experimental Station, East Java, Indonesia during dry season 2018. The results showed that the descriptive characters of 300 mungbean germplasm accessions had a fairly wide range, namely 50%-flowering date ranged from 30-50 days after planting with an average of 41.92 days, Pod maturity ranged from 50 - 88 days after planting with an average of 74.08 days, 100-seed weight ranged from 2.43 to 7.96 g with an average of 4.52 g, and Seed weight per plot ranged from 10 - 525 g with an average of 254.53 g. There were three accessions with seed size more than 7.5 g/100 seeds, namely MLGV 0713, MLGV 0960, and MLGV 1027. These accessions could be used as a source of genes for developing high yielding and large seed size of new improved mungbean varieties. Furthermore, the high diversity data in mungbean collection can provide information to used by breeders.
