“…General combining ability (GCA) of the five parental lines was the principal source of variation among genotypes, although specific combining ability (SCA) variance was also significant for most characters evaluated, except number of nodes on main stem and yield in the F2, and number of seeds/plant and yield in the F3. The predominance of GCA variance for yield and other architectural traits in common beans has been reported in other genetic studies (Hamblin & Evans, 1976;Nienhuis & Singh, 1986, 1988. General combining ability effects for yield were negative and significant for the two type I lines, PVA5 and ICA10101, but of the five parental lines evaluated, only these two produced progeny with significantly larger seed size (Table 3).…”

“…Entretanto, como a seleção precoce em feijão apresentou baixa eficiência (HAMBLIN & EVANS, 1976;PATIÑO & SINGH, 1989), o emprego da nota geral de adaptação deverá ser avaliado nas etapas iniciais do programa de melhoramento, quando é alta a interação famílias x anos (CUTRIM et al, 1997). Se a nota geral de adaptação apresentar alta associação com a produtividade de grãos em gerações precoces, esta poderá ser útil também, em trabalhos de seleção indireta que visam à melhoria da produtividade de grãos em feijão.…”

“…A seleção precoce apresenta baixa eficiência em feijão (HAMBLIN & EVANS, 1976;PATIÑO & SINGH, 1989), pois, nas gerações iniciais (F 2 , F 3 e F 4 ), a interação famílias x anos é significativa (CUTRIM et al, 1997), dificultando a seleção de caracteres quantitativos, como a produtividade de grãos. Para tanto, estimativas de coeficientes de correlação linear entre caracteres têm sido obtidas e utilizadas como estratégia de seleção indireta.…”

To simultaneously improve qualitative and quantitative agronomic traits, markers and gamete selection can be used. However, the effectiveness of alternative methods of yield testing in early generations must first be investigated. In this study, we therefore determined the relationships between seed yield of F1-derived families and of population bulks in F2 and F3 generations. We also compared seed yields of a high-versus low-yielding population in F2 and F3 with their advanced generation (F7) lines. First, we yield-tested 25 multiple-parent, interracial and inter-gene-pool populations, each represented by their population bulk, and 24 F1-derived families, at three locations, in F2 (1993) and F3 (1994). Each plot of the bulk of each population consisted of four rows and was replicated twice. The 24 F1-derived families were randomly divided into six groups of four. The four families of each group were sown together to represent one plot of each replication. But each family was harvested separately and the mean yield of the four families represented the plot yield. Then, based on the mean seed yield of F2 and F3, one comparatively high-yielding and one low-yielding population were selected. Ten F4-derived F7 lines from each population were yield tested at the same three locations in 1995–1996. Positive correlations were found between the mean seed yields of F2 and F3, and between the seed yield of population bulks and the yields of F1-derived families in both F2 and F3. The mean seed yield of the 10 F4.7 lines from the high-yielding population was significantly higher (P < 0.05) than that of its counterpart from the low-yielding population. Marker-assisted gamete selection for qualitative traits during hybridization and population development in the F1 can therefore be combined with yield selection among F1-derived families in early generations of common bean populations. Key words: Common bean, Phaseolus vulgaris L., gamete selection, early generation yield testing
