Differences of seed size between several Dolichos lablab L. accessions in Indonesia

Dolichos lablab L. (komak bean) is a legume plant that has potency as a nutrient-rich food (fiber, protein, and minerals), however, its cultivation is still not optimal in Indonesia. Moreover, researches on D. lablab L. from Indonesia remains rare. This study aims to reveal the diversity of D. lablab L. seeds morphology which are spread in various regions in Indonesia. 13 accessions of D. lablab L. were obtained from Madura, Malang, Probolinggo, and West Nusa Tenggara. Morphological observations of seeds which include the parameters of length, width, thickness, and weight of seeds were carried out on all accessions collected. Furthermore, the data were analyzed using a one-way analysis of variance (ANOVA) by positioning accessions as independent variables and the size of the seeds as the dependent variable. The findings suggests significant differences in length (F = 9.335, p <.05), width (F = 2.906, p <.05), thickness (F = 6.293, p <.05), as well as seed weight parameters (F=41,488, p <.05). In general, West Nusa Tenggara 2 and Probolinggo 1 have the largest seed size, while Probolinggo 2 has the smallest seed size. Findings that inform the size of the D. lablab L. seed differentiation can be used as a basis for subsequent studies.
