Abstract:
Lathyrus sativus is nutritive hardy pulse crop. The major constraints of Lathyrus sativus is the presence of neuro-toxic non-proteinogenic amino acid β -N-oxalyl-L-ɑ,β-diaminopropionic acid (β-ODAP) and low yield. Hence, it is inevitable to select the low β-ODAP content Lathyrus sativus for safe consumption. Therefore, after screening diverse genotypes, a breeding population as developed by crossing low ODAP containing Maharera and high ODAP containing RLK-1950 to identify low seed β-ODAP containing genotypes with higher seed yield. Phenotypic traits and seed β-ODAP content of the segregating population (F3) were evaluated. It was found that biological yield per plant was significantly and positively correlated to pod yield per plant, seed yield per plant and seed β-ODAP content. Similarly, pod yield per plant was significantly and positively correlated to biological yield per plant, seed yield per plant and seed β-ODAP content. However, seed yield per plant and seed β-ODAP content had positive but non - significant correlation. Considering higher seed yield per plant and low seed β-ODAP content (<0.3%), four Recombinant Inbreed (RI) F3 lines viz. RIL no. 29, 120, 134 and 189 were identified. These lines will be used for further generation advancement and yield evaluation.
