Abstract
The aim was to form and study a national rice collection, identifying accessions by economically valuable traits for further use in breeding.
Results and Discussion. The results of the national rice
collection allowed for identification of sources of economically valuable
traits: growing period, yield, plant height, panicle performance, vitreousness,
stress crack, total output of groats and whole kernels, disease resistance
(blast disease), etc. Of the studied accessions, valuable for breeding varieties
and lines were selected as sources of individual valuable traits (UIR 3095,
Marzhan, UIR 8493, Viаlone Nano, Pashali, Aral 202, Egyption gasmine, Cheope).
The UIR 3095-14 line received a registration certificate for a plant gene pool accession
in
Conclusions: For effective breeding work, constant studies of the national rice collection are conducted. Varieties and lines – sources of valuable traits have been identified; their inclusion in breeding in the future will make it possible to obtain varieties that maximally combine several economically valuable traits in one genotype.
