Abstract

In garden pea, the availability of produce early in the season provides a premium price to the growers. Keeping this in view, efforts were made to develop varieties with stable performance across environments for early maturity and high pod yield.

48 lines were evaluated in Alpha Lattice design over 7 diverse environments ranged from sub-tropical to dry temperate conditions of north-western Himalaya during 2016-17 and 2017-18.

Genotypes SP-22, SP-18, SP-2, SP-17, SP-12, SP-6, and SP-3 showed earliness for days to flowering and first picking, significantly better than check Pb-89 and were also stable (S2di=0 and bi=1) except SP-6 and can be adapted to suboptimal environmental situations. The environment (E6-Kukumseri) was the most ideal for the first flowering node while E1-Bajaura for days to flowering and first picking. Mean vs stability biplot and “which-won-where” depicted SP-6, SP-22, SP-17 and SP-18 as the most stable and winning genotypes for early flowering and picking. SP-6 and SP-22 are the most promising genotypes with stable performance across environments for early maturity and high pod yield based on GGE biplot and AMMI, respectively. They could be a better alternative to the popular growing variety Pb-89 in the north-western Himalayas.
