| Title : | GENOTYPE-ENVIRONMENT INTERACTION AND STABILITY ANALYSIS IN GARDEN PEA (PISUM SATIVUM L.) LANDRACES |
| Abstract : | Knowledge of presence and magnitude of genotype-environment interactions (GEI) is important to plant breeders in making decisions regarding the development and evaluation of new cultivars. The present investigation was undertaken to identify the stable landraces across different environmental conditions. Ten landraces of garden pea were evaluated for their adaptability in respect of green pod yield and fresh biological yield for three successive seasons 2010/2011–2011/2012 and 2012/2013 at one location. The stability of landraces was assessed using mean yield (͞Xi), linear regression of genotypes on environmental index (bi) and deviation from linear function (S2di). The combined analysis of variance showed highly significant differences among the landraces for both traits studied. Mean squares due to GEI were highly significant indicating that landraces performed differently through the environments of study. Analysis of variance for stability showed higher magnitude of mean squares due to environments (linear) as compared to genotype-environment (linear) exhibiting that linear response of environments accounted for the major part of total variation for pod yield and biological yield. The results revealed that just the landrace 12420 was found to be high performance, stable and widely adaptable for green pod yield, whereas the three landraces 20648, 12420 and 12831 were found to be good yielding, stable and widely adaptable for fresh biological yield. |
