초록

A complete diallel cross was performed to
determine the inheritance of 1,000 grain weight of brown
rice and cyanidin-3-glucoside (C3G) content and combining
ability of five pigmented rice that showed different level
of C3G content. Parents and F₁ of 20 crosses were evaluated
for 1,000 grain weight of brown rice and C3G
content which extracted from pigmented rice grain with
0.1% trifluoroacteic acid (TFA) in 95% EtOH. For 1,000
grain weight of brown rice and C3G content, both additive
and dominant gene effects were detected and the dominance
was partial and there were more dominant alleles
than recessive ones. Genetic parameters pointed out that
there are significant additive and dominant effects and the
additive effect is bigger than the dominant one for both
grain weight and C3G content. The frequency of negative
alleles were higher than positive alleles. Narrow sense heritability
estimates were 0.66 for grain weight of 1,000 brown
rice and 0.70 for C3G contents. General combining ability
(GCA) effects and specific combining ability (SCA) effects
were highly significant and GCA effects were drastically
higher than SCA ones. It indicates that the inheritance of
the C3G contents is controlled mainly by additive genetic
factor.
