PATERNAL AND MATERNAL EFFECTS ON PROTEIN AND OIL CONTENT IN SUMMER RAPE

Abstract

Comparisons among self- and cross-pollinated seeds from two summer rape (Brassica napus L.) cultivars, Midas and Tower, suggest that protein and oil contents of the seed are determined by the genotype of the plant which produces the seed. Pollen source also appears to have a slight effect on oil content. Comparisons among seed samples produced by the F1 and F2 progenies, derived from reciprocal crosses, indicate that protein and oil contents of the seed are controlled by nuclear genes and not by extranuclear determinants.
