Selection of the best breeding technique for the development of new maize
hybrids is based on knowledge of gene effects type responsible for the
expression of quantitative traits. Thus, the goal of this study was to evaluate
gene effects on the grain yield, as the most important agronomic trait, as
well as for kernel oil content. one of the major characteristics of maize
quality.
Genetic material used for the determination of gene effects consisted of
four inbred lines: 1109/1V NS, 56811 NS, 922 NS and A-l. Inbred line
1109/1V NS is high oil inbred line, and 568/11 NS, 922 NS A-1 are lines
with a different type of seed: dent, semi-dent and flint, respectively. Six
basic generations were produced: parental inbred lines (Pi, Pa), first and
second filial generations (Fy, F2) and backcross generations (BC), BC2).
Two years experiment was performed at the experimental field of the
Institute of Field and Vegetable Crops, Novi Sad, Serbia (Rimski Sangevi)
using a completely rand...omized design with eight replicates. Evaluation of
gene effects was performed by generation mean analysis.
Obtained results indicated that dominant gene effect had a higher influence
than additive in inheritance of the grain yield. The significant presence of
duplicate type of epistasis was recorded in all test-cross combinations. For
kernel oil content dominance was more important than additive gene action
for almost all studied test-crosses. Additive gene effect was higher than
dominance only for hybrid 1109/IV NS = 56811 NS. Morcover, a
significant presence of duplicate type of cpistasis also was detected for
kernel oil content.
The significant role of the dominant gene effect in the inheritance of grain
vield and kernel oil content in almost all test-cross combinations indicates that inbreding-hybridization method is a useful method for the development of
better hybrids.
