Abstract

Seed storability of 22 selected soybean mutant lines from Argomulyo population irradiated by gamma ray were assessed by rapid aging tool, APC-IPB 77-1MM. Seed viability and vigor parameter observed due to genetic factors. The 90% ethanol was applied for 20, 40, 60 and 80 min as accelerated aging test. M100-96-53-6 was estimated that has good storability with less seed deterioration rate expressed by slow slope of germination percentage, germination speed and electrical resistance value after 20-80 min of chemical accelerated aging. Electrical resistance (ER) test could be as alternative and a substitute of electrical conductance (EC) test as alternative of vigor test. The high heritability and moderate to high genetic advance were noted on all parameters except moisture content. Germination percentage and germination speed could be reviewed for early stage selection to improve traits at the next generation based on R-square value of regresion and genetic parameters obtained.

Highlights

Soybean, as source of functional food, containing about 37% of vegetable protein is one of the important legume crops in Indonesia with 0.539 million tons in 2017 (Ministry of Agriculture, 2018)
These moisture content values are recommended for storing of soybean seeds that have high protein content
The uniform seed moisture contents of 2934% were noted after moisturizing and decreased between 28-31% after accelerated aging of each duration in contrast to Toledo et al (2011) who reported uniformity of seed moisture content in each exposure duration and their increasing after time passed

Summary

Introduction

As source of functional food, containing about 37% of vegetable protein is one of the important legume crops in Indonesia with 0.539 million tons in 2017 (Ministry of Agriculture, 2018). It can be used as raw material due to about 25% of its oil content (Pereira et al, 2011). High production and productivity to achieve soybean self-sufficiency must be supported by supplying superior varieties with high quality seeds. Mutation breeding providing a source of genetic variation by developing and increasing genetic variability through mutation induction is necessary for improving crop yield and quality (Shu et al, 2011)
