PHENOTYPIC STABILITY AND GGE BIPLOT ANALYSIS IN PIGEONPEA [CAJANUS CAJAN (L.) MILL SP.] GENOTYPES ACROSS THE ENVIRONMENTS
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
Phenotypic stability was carried out by using Eberhart & Russell model, as well as recent GGE biplot approach for identification of the foremost genotypes across the different environments in pigeonpea [Cajanus cajan (L.) Millsp.] genotypes. Further, Pearson correlation was carried out to correlate the different yield contributing attributes with seed yield. Fifty six pigeonpea genotypes comprising fourteen parents, forty hybrids and two standard checks were evaluated at four environments during kharif season of 2013 and 2014, to study genotype × environment interaction for yield and related traits. A significant difference was obtained for yield and yield contributing characters among genotypes in individual as well as pooled environments except for pod length, 100 seed weight and seed protein content (%). For traits like days to maturity, plant height, pods per plant, pod clusters per plant, seeds per pod, 100 seed weight and seed yield per plant Genotypes × Environments (linear) values were significant when tested against pooled deviation. Some hybrids such as GT 610 A × GTR 84 (119.79 g), GT 603 A × GTR 81 (119.41 g), GT 610 A × GTR 82 (119.20 g), GT 607 A × GTR 82 (116.07 g), GT 601 A × GTR 82 (113.03 g) and GT 604 A × GTR 81 (110.92 g) depicted significant stability for the yield and yield components by Eberhart & Russell model. Similar results were observed by GGE biplot analysis for three hybrids viz., GT 610 A × GTR 84 (119.79 g), GT 603 A × GTR 81(119.41 g) and GT 610 A × GTR 82 (119.20 g) which depicted significant stability for the yield and its components and could be promising for cultivation across different environments in Western India.
