CORRELAÇÃO ENTRE OS PARÂMETROS DE ESTABILIDADE E DE ADAPTABILIDADE DE CULTIVARES DOS MÉTODOS DE CRUZ, TORRES & VENCOVSKY E MOREIRA & PEREIRA

摘要: MOREIRA, L. B.; PEREIRA, M. LOPES, H. Correlation among cultivars stability and adaptability parameters calculated by methods of Cruz, Torres & Vencovsky Moreira Pereira. Revista Universidade Rural: Serie Ciencias da Vida, Seropedica, RJ: EDUR, v.26, n.1, p.33- 41, jan-jun, 2006. In this work it was used data base obtained trials in the agricultural year 1992/93 conducted AS-PTA collaboration with Brazilian Enterprise for Agricultural Research (EMBRAPA, Agrobiologia). study forty-nine maize genotypes were appraised nine South Southeast locations Brazil. Using those experiments, association degree (1989) Pereira (2001) analyzed evaluated, means Spearman's rank correlation. The â 2 parameter showed positive significant correlation 1 + , indicating adapted to favorable environments. contributed additional information explain genotype at evaluated locations. QM dl e dq QMd, being therefore quite similar classification according their stabilities different environmental conditions. SDi statistics may be as an option identification unfavorable This is associated general average regression linear coefficient compared quadratic model
