During 2012-2015 from the two fissile populations
of rice hybrid Il.14 x Kuboyar and Il.28 x Kuboya
we conducted multidirectional selection of panicles
with low, medium and high number of grains in
them. It was established a different reaction to the
selection of hybrid generations by yield. The lowest
yield was formed at planting grain from small panicles,
intermediate - from the middle panicles and
biggest - from the major panicles. The reaction to
selection decreased with each successive generation.
In the hybrid Il.14 x Kuboyar at positive selection of
the yield increase towards the initial population F2
was in F3 - 10,5%, in the F4 - 3,8% and F5 - 1,9%, at
Il.28 x Kuboyar - respectively 4, 4%, 3.1% and
0.7%. At negative selection in Il.14 x Kuboyar there
was a decrease of yield on 7.7% F3, in F4 on 6.9%
and in F5 on 0.2%. By years of research was not observed
variations in grain yield obtained from the
panicle with an average grainness and generally was
at the level of the original population. At the hybrid
Il.28 x Kuboyar for negative selection of the relative
yield initially decreased on 1.7% in F3, while then for
all kinds of selection to the fifth generation grew up
and different to a lesser extent than the first the hybrid,
although the ranks of the values preserved. The
yield from a fraction of well-grained was 98.4%,
medium grained - 96.5%, low grained - 94.2% of the
initial Kuboyar variety
