Seed storability behaviour of Lathyrus (Lathyrus sativus L.) genotypes

Abstract

The present investigation was conducted to understand the storability behaviour of the lathyrus which has received very little research attention till date. Therefore, 360 accessions of lathyrus were stored at medium term storage and the viability was monitored after 10 years of storage. The result indicated that out of 360 accessions 320 accessions recorded 0% viability, 30 accessions recorded < 5% viability; 1 accession (EC 329738) recorded 50 60% viability; 5 accessions (RLK 552, RLK 1208, IC 120449, RLK 1159, KH 1) recorded 80-90% viability and 4 accessions (RLK 1054, RLK 287, RLK 1191, RLK 84) recorded > 90% viability after 10 years of storage. Therefore, the best performing accessions (RLK 1054, RLK 287, RLK 1191, RLK 84) which recorded viability of > 90% even after 10 years of storage were identified as the good storer genotypes which can be utilised in improving storability in lathyrus.
