Determining the most stable potato hybrid using AMMI yield stability analysis method

Genotype-environment interaction (GEI) is very important for breeders. It considered a complicated issue in breeding programs to obtain stable and high-yielding genotypes release new genotypes. This study was conducted achieve genotype that adaptive climatic conditions of potato-producing regions Iran. A total 20 potato lines along with five commercial varieties (Savalan, Agria, Caesar, Luta Satina) were evaluated randomized complete block design three replicates the Agricultural Research Natural Resources Stations location (Ardabil, Razavi Khorasan, Karaj, Isfahan Hamadan) Iran, two years (2016 2017). Combined ANOVA yield data studied environments indicates significant differences among genotypes, environments, GE significant. Thus, AMMI method its parameters used analyze stability. The results indicated only four principal components (P<0.01), which accounted 81.2% GEI sum squares. Based on type 1 (SIPC1, FA1, Za1, Dz1, EV1, Da1), G7, G10, G14, G20 G24 identified as be stable. Moreover, according 2, 3 4 parameters, G2, G6, G15 G20, well cultivars Agria (G24) (G23), found Genotypes G15, ASV parameter, G6 G7 based MASV parameter. Amongst by while high-yielding, G14 (Agria) moderate-yielding.
