Diallel Analyses of Fatty Acids in Corn (Zea mays L.) Oil1
- C.G. Poneleit and
- L.F. Bauman2
Genetic, reciprocal, and environmental variation of oil content and Catty acids was examined in F1 and F2 diallel crosses of nine inbred corn lines. The GCA mean squares were much larger than SCA mean squares for each variable. Relative rank of GCA effects for inbreds could be predicted directly from the inbred means. Breeding systems which effectively use additive genetic variation are suggested as most useful for alteration of either oil quantity or quality. The significant but low correlations found for some of the fatty acids with oil quantity indicate concomitant selection for both quality and quantity should result in progress. Reciprocal differences Cor percent oil were positively correlated with (1) the mean of the F1 crosses and (2) the difference between the parental inbreds of an F1.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
