| The oil content of soybean (Glycine max (L.) Merrill) seeds is a polygenic and complex trait that is responsive to environmental effects that occur during plant development. Our objective was to study the seed oil content of soybeans developed under diverse photoperiod and temperature conditions. Three parental inbred lines with classic (BR-13, FT-2 and BR85-29009) and one with long juvenile flowering type (OCEPAR 8) and the F2, F3, and F9 generations derived from all possible crosses between them (including reciprocals) were sowed in September 27th, October 20th and December 17th in 1993 in Londrina, Paraná State, Brazil (between 23o08'47" and 23o55'46" latitude S). The October and December sowing dates are within the period the varietal research... |
