The inheritance of plant height was investigated in a ten-parent
diallel cross of diverse rice cultivars. Parents included two tall japonica
lines and eight semidwarf lines. Data from parent, F1, F2
, and F3 generations indicated that the majority of height
variation among the ten parents could be accounted for by three major genes
with additive loci effects. D51, 72/2234–11, and G33 (derived from the
known major-gene indica semidwarf Dee-geo-woo-gen) all were found to possess
an allelic, partially recessive semidwarfing gene (sd1).
Additional semidwarfing genes were detected in D66 (sd2,
fully recessive) and in CI 9858 (sd3, partially to fully
recessive). Relative magnitudes of additive effects were sd1 >
sd2 
sd3. Hokuriki 76, Tedoriwase,
and IV 29–4 were found to be dwarfed by a multiple-gene system. Hayman-Jinks
diallel cross analysis on parent and F1 information (1974 and 1975)
and on parent and F2 information demonstrated the presence of significant
additive and dominance variation, but epistasis was not detected. A preponderance
of dominant alleles with partial dominance for increased plant height was
observed. Since diallel statistics reflect properties of genes with larger
effects, the genetic model proposed from segregation analysis was in substantial
agreement with predictions of the Hayman-Jinks analysis.
