Multi-trait multi environment analysis for stability in MABC lines of Chickpea (Cicer arietinum)

Fusarium wilt (Fusarium oxysporum f. sp. ciceris) is a major disease that can cause up to 90% yield loss in Chickpea (Cicer arietinum L.). The presence of 8 physiological races Foc (0, 1A, 1B/C, 2, 3, 4, 5 and 6) makes it complex task the development disease-resistant cultivar. Thus, Pyramiding 1, 4 was undertaken using WR 315 as donor Pusa 372 recurrent parent through Marker assisted backcross (MABC) breeding approach. A total 20 genotypes, including 17 MABC derived lines × 315, susceptible (Pusa 372), resistant check (WR 315) national (JG 16) were used. Multi-location testing advanced at different regions (Amla, Badnapur, Sehore, IARI-New Delhi) carried out randomised block design (RBD) two replications during 2020–21 winter (rabi) season. Usually, multi environment performed involving single trait, which provides lower reliability selection lines, compared multi-trait analysis. present study identifies highly stable with higher advantage MTSI (Multi trait stability index) GGE (Genotype main effect genotype interaction) biplot methodology. From analyses PC1 explains 84.97% PC2 8.96% variability. results revealed (G) 3 for multiple characters studied. But, based on GGE-mean value G 11, 12 identified better values. Based GGE, may be considered line traits superiority.
