In: Crop Science (USA)Summary: Se investigo la asociacion de distancia genetica y heterosis en frijol comestible y en habas. poblaciones F2 de un dialelo de 8 x 8, y sus progenitores resp., los cuales se cultivaron en 8 repeticiones en el campo en East Lansing (Michigan, EE.UU.), durante 1981. distancias geneticas fueron significativas en frijol, y ademas altamente significativas en cuanto al rendimiento en el momento de la cosecha y a 2 de los 3 componentes del rendimiento, o sea, no. de vainas/planta y no. de semillas/vaina. Se obtuvo una correlacion positiva altamente significativa en el peso foliar. (RA-CIAT)Summary: The association of genetic distance and heterosis was investigated in dry edible bean and faba bean. Dry bean materials consisted of 28 F2 populations of an 8 x 8 diallel, and their resp. parents, grown in 8 replications in the field at East Lansing (Michigan, USA) in 1981. Correlations in dry beans between heterotic effects and parental distances were positive and highly significant for yield at harvest and for 2 of the 3 yield components, namely, no. of pods/plant and no. of seeds/pod. No relationship was found for 100-seed wt. A highly significant positive correlation was obtained for leaf wt. (AS)
