Abstract

 ABSTRACTThe yam bean seeds are formed in relatively long pods containing between 6-12 seeds/pod. A total of six local yam bean accessions from Indonesia was studied for its seed position in pod related to seed viability and vigor. Field research was carried out in Malang (Indonesia) from May - October 2016. Twenty five matured pods were detached from each accession. Each pod was divided into three parts, i.e. base, middle, and tip part. The seeds of each part are mixed and taken as many as 20 seeds for germinating. The design was a completely randomized design with two factors and repeated three times. The first factor was three seed positions (base, middle, and tip) and the second factor was six accessions of Indonesian local yam bean. The analysis of variance showed that seed position had significant effect on individual seed weight, leaf length, leaf width, leaf shape index, seedling dry weight, and root dry weight. Seeds derived from the midde of the pods produce the highest leaf length, leaf width, leaf shape index, seedling dry weight, and root dry weight. The parameters of seed viability and vigor were not affected by the seed position in the pods. Therefore, the seed viability and vigor of yam bean plant in the field can be produced from the seeds derived from the tip, middle and base of the pod. Keywords: seed position, viability, vigor, yam bean

Abstract

ABSTRACT Pod shattering is one of major constraints in soybean cultivation at tropical environment. The objective of the study was to evaluate resistance to pod shattering and agronomic performance of several  adapted to tropical environment. A total of 14 promising lines and two check cultivars (Anjasmoro and Dega 1) were evaluated in two locations (Mojokerto and Jembrana) on Februari to May 2018. The experiment design was a randomized block in each location, with 16 treatments and four replications. At R8 stage, 30 pods were randomly detached from five sample plants of each line to be used for evaluation of pod shattering resistance using oven dry method. Five promising lines from Mojokerto showed resistant to pod shattering, meanwhile three very resistant and two resistant lines were obtained from Jembrana. Those all resistant promising lines were the progenies of shatter-resistant parent (Anjasmoro). The pod shattering resistance was determined by the pod length, the longer the pods will increase sensitivity to shattering. However, the sensitivity of long pods can be minimized when width of the pod is narrow. The promising lines with shorter pod and the width of the pod is narrow, then this line has the chance to be resistant to pod shattering.  The agronomic characters of soybean are suitable to be developed in tropical regions such as Indonesia are: maturity under 85 days, seed weight more than 14 g/100 seeds, medium plant height, and produce high number of pods. Based on the results of the study obtained one promising line which resistance to pod shattering, produce high productivity and have good agronomic characters. The lines is G511H/Anj//Anj///Anj////Anj-4 with production yield 3.43 t/ha and also adaptable to the tropics.   Keywords: pod shattering, agronomic character, tropical soybean, path analysis
