Evaluation of several soybean genotypes for pod shattering resistance

Abstract Shattering in soybean occurs after the pods reached maturity which can cause considerable yield loss. The aims of this study were to evaluate the pod shattering resistance and the performance of the agronomic traits of several soybean genotypes. The field study was conducted at Banyuwangi (Indonesia) from July to October 2018 using twelve soybean genotypes. Pod-shattering evaluation was done as per oven-dry and sun-drying methods. The variability of shattering start to occur at oven temperature treatment of 50°C and 60°C. Based on the oven-dry method, two genotypes were found resistant, three genotypes were susceptible, and seven genotypes were highly susceptible to pod shattering. Based on the sun-drying method (15 days drying), two genotypes were categorized as resistant, three genotypes were moderate, five genotypes were susceptible, and two genotypes were highly susceptible. Soybean genotypes ATgt-18-009 and Anjasmoro showed consistently resistant to pod shattering based on the oven-dry as well as sun-drying methods. Those genotypes also produce high yield (more than 3.0 t/ha) with days to maturity ranging from 82 to 85 days, therefore it could be potentially developed in the soybean production centers in Indonesia.
