Characterization of grass pea (Lathyrus sativus L.) germplasm collections for beneficial agronomic traits

Published on

At ICARDA, germplasm collections obtained from five
countries namely, Bangladesh, Ethiopia, Syria, Nepal and
Pakistan were grouped in to seven sets of trials (BANG1,
BANG2, ICARDA, ETH1, ETH2, NEP, PAK) and evaluated in
two experimental locations, Tel Hadya and Breda over eight
years. Characterization was done for the most desirable
agronomic traits such as days to first flowering, days to
95% maturity, biological yield, seed yield, hundred seed
weight and harvest index. Significant genotypic and
interaction effect were found for the expression of the traits.
Substantial amount of variability was revealed in the
germplasm collections for most of the traits. High broad
sense heritability was observed for days to first flowering
and hundred seed weight indicating early phenotypic
selection of these two traits. The stability over years for the
seed yield (in terms of the CV), identified promising
accessions such as ILG2178 in BANG1 and ILG1721,
ILG1632, ILG1624, ILG1540 and ILG1501 for future breeding.
