Uncovering rain-fed resilience power of grass pea in Iran using AMMI, BLUP, and multi-trait stability parameters.

ABSTRACT: Rain-fed regions have a low quantity of rainfall with an asymmetric distribution. Therefore, by promoting plants like Lathyrus sativus L., as a legume adapted to unfavorable environments, genotypes with high fodder capacity under such conditions would assist food security worldwide. Here, 16 grass pea genotypes were examined in four rain-fed regions during 2016-2017, 2017-2018, and 2018-2019. Dry fodder yield (DY), plant height (PH), days to flowering (DF), and wet fodder yield (WY) were recorded across 12 test environments. Regarding MLM analysis of variance, LRT_ENV and LRT_ENV×GEN were significant for all studied traits. Phenotypic variance ranged between 1.42 (DY) to 86.9 (PH). Results showed the possibility of grass pea improvement through selection regarding calcu
