Analysis of the relationship between physical and chemical characteristics with the shelf life of long beans

Abstract

Abstract Long beans are one of the vegetables that are widely planted in Indonesia. Shelf life is a prominent characteristic that needs special attention in breeding programs. This research aims to analyse the close relationship between pods’ physical and chemical characteristics and the shelf life of yard-long beans. This research method uses a randomized block design and correlation regression analysis. The sample used seven genotypes of yard-long bean pods. The characteristics observed included pod length, diameter, hardness, water content, protein, and total soluble solids. The results showed that the pod length and diameter of the seven sample genotypes tested were not significantly different. At the same time, there were significant differences in hardness, moisture content, protein, and total soluble solids. The relationship varied from very weak to strong, respectively, from pod length, total soluble solids, hardness, diameter, water content, and protein. The water content and protein showed a close relationship with correlation coefficients of 0.76 and - 0.79, respectively. The results of this study were useful for breeders, especially in the shelf-life evaluation of yard-long bean accessions.
