A Study on Germinability, Vigour and Storability of Seeds of 18 Soybean lines

Abstract

Seed quality of 18 soybean lines from AVRDC was evaluated by standard germination test, field emergence test and accelerated ageing test. It was found that seed germination of 18 soybean lines varied from 54 to 94 % and they were divided into 3 levels of germinability. By considering initial seed germination together with another 2 tests, it revealed that KUSL 10006, SJ4, SJ5, KUSL 20004, KUSL 20043, KUSL 20050, CM 001-1 and 8122-7 were the soybean lines that produced high quality seeds while CM60, KUSL 10001, KUSL 10009, SK1, and LN14 showed the poorest quality. The rest, i.e. KUSL 20010, KUSL 10008, KUSL 30006, KUSL 10002 and KUSL 20018 could be judged as medium quality. According to the seed storability indices which were estimated after 3 months of storage, it was found that 8122 – 7, KUSL 20043, KUSL 20004, KUSL 20010, KUSL 10002 and KUSL 20018 seemed to be intersting lines in terms of seed storability.
