The Diversity of Seed Size and Nutrient Content of Lablab Bean from Three Locations in Indonesia

Abstract

Lablab bean (Dolichos lablab L.) is one of the legume species that have the potential as an alternative food source for Indonesian people. The purpose of this study was to examine the diversity of seed size and nutritional content of six lablab bean accessions found in the Madura, Probolinggo, and West Nusa Tenggara (WNT), Indonesia. Morphological observations of seeds which included parameters of length, width, thickness, and seed weight, while the nutrient content of seeds was obtained from proximate analysis which included assay of fat, protein, and amylose. Data analysis used in this study wasa one-way analysis of variance and Pearson Product Moment test. The results of the analysis showed that the variety of accessions had a significant effect on all morphological parameters and nutrient levels studied. Besides, the results of data analysis also inform that some morphological parameters and nutrient content have a significant correlation.The findings of this study also show that lablab seeds contain high protein and amylose, so the use of this plant as alternative food in Indonesia is highly recommended.

Association of Seed Amylose Content with Agronomic Traits and GBSS1a Haplotypes in Common Bean Landraces

“…The results showed that amylose content was positively correlated with PW, SW, SA, 100SW, SP and SL. Purwanti et al (2019) reported a significant positive correlation between amylose content and seed size in lablab bean (Dolichos lablab L.) seeds, consistent with the current study on common bean seeds. On the other hand, we also found that SNPP showed a negative correlation with amylose content and seed size, implying that an increase in SNPP is accompanied by a decrease in seed size, resulting in lower amylose content.…”

Nutritional Contents and Bioactive Compounds among Several Variants of <i>Dolichos lablab</i>: Fundamental Facts for Functional Food Development

“…There are many species of legumes worldwide, but not all beans are known in the society. One of the underutilized legumes is Lablab beans (Dolichos lablab), also known as Koro Komak in Indonesia (Purwanti et al 2019b). Natively grown in the African continent and Indian subcontinent, Lablab beans have become the primary source of energy due to their rich fibre and carbohydrate contents (Maass et al 2010;Purwanti et al 2019a).…”

“…Three primary accessions or variants of Lablab beans have been identified in Indonesia (Purwanti et al 2019b). Those accessions are commonly identified based on the beans' colour, i.e., brown, black, and cream (figure 1).…”

“…Those accessions are commonly identified based on the beans' colour, i.e., brown, black, and cream (figure 1). Although other variants may exist, these three are commonly found in several regions in Indonesia, such as East Java (Probolinggo and Madura Island) and West Nusa Tenggara (Purwanti et al 2019b). The previous study reported the bioactivity of bioactive compounds and nutritional values of Lablab beans (Purwanti et al 2021;Purwanti et al 2022).…”

“…The sample of the beans for this study was obtained from Sumenep, Madura Island, East Java, Indonesia during dry season in 2019. Details of the sample profiles and precise locations are as described in the previous study (Purwanti et al 2019b). The beans were stored in 4°C until used.…”
