AMMI approach for seed yield and stability of french bean (Phaseolus vulgaris L.)

Abstract

Eleven french bean (Phaseolus vulgaris L.) genotypes including four checks (Table 1) maturing in 68 to 75 days were grown in 1.8 x 4.5 m2 plot with 30 and 10 cm spacing between and within rows, respectively in a randomized block design with three replications during kharif 2002 at five different agro-climatic locations in the french bean growing region of plain zone in University multilocation trial. Recommended dose of fertilizers 60 kg Nand 80 kg P20s/ha was applied. The data generated on seed yield of french bean were analysed as per Zobel et al., [1] and Gauch and Zobel [2], using IRRISTAT software developed by International Rice Research Institute, Phillippines. Hierarchial cluster analysis was also performed on the residuals from the additive model in order to cluster varieties and environments with respect to interaction effects.
