Number of experiments that should be considered in the cluster analysis of common bean genotypes for plant architecture and grain yield traits

The number of experiments that allows the choice parents to be used in controlled crossings a more assertive way cluster analysis is unknown for plant architecture and grain yield traits common bean. Therefore, objective this work was determine should considered Tocher's unweighted pair group method with arithmetic mean (UPGMA) analyses identify promising bean several traits. Four were carried out different years growing seasons, same site. randomized block design 17 genotypes carioca (beige seed coat brown streaks) black grains evaluated relation 12 related five yield. Statistical performed data obtained from individual combined experiments. Significant genotype × experiment interaction observed most When UPGMA groups formed. use two, three or four allowed greather reliability formation groups. Three two are sufficient analyses, respectively, way.
