Popis:	Information on the genetic behavior of early-maturing soybeans (Glycine max (L.) Merr.) in northern latitudes is important for the formulation of appropriate selection schemes. The Gardner-Eberhart diallel model was used to study genetic effects and combining abilities of 11 early-maturing genotypes (maturity Groups 00 and 000) of soybean grown in Quebec and eastern Ontario. Agronomic characters were measured on spaced F1 plants at one site, and on F2 populations in replicated row plots at three sites. Cultivar (additive) effects were predominant for all characters. Three of eleven lines had positive but unstable varietal parameters for seed yield. Average heterosis was significant for seed yield and plant height at every location. Contrary to other reports, significant negative heterosis for oil content was observed at two locations. Varietal and specific heterosis were significant for most characters.Key words: Soybean, Glycine max (L.) Merr., diallel, Gardner-Eberhart, yield, oil, protein
