DETECTION AND ASSESMENT OF RED CLOVER GENETIC SOURCES WITH SELF-COMPATIBILITY FOR DEVELOPMENT THE VARIETIES WITH HIGH AND SUSTAINABLE SEED PRODUCTIVIT

The basic limiting factor in development of clover-sowing is the deficit and high cost of seeds. Our investigations were directed to search, selection and study of self-compatible genotypes of red clover (Trifolium pratense L.). Progeny of a genetic source with self-compatibility (No 3000 I1) exhibited this property with the level from 18 to 100%. The No 3000 I1 and the varieties “Ranniy 2” and “VIK 7” were compared by morphological and biological properties. The studied sample had longer vegetative period, abundant foliage, was stunting, formed more stems, and contained more dry matter and protein. Self-compatibility was highly inherited under reciprocal crossing with diploid variety “Ranniy 2”. Among progeny F1, under the direct crossings we selected 53% of genotypes with 50% rate of self-compatibility and under the backcrossing — 74%. Thus, the studied initial material is recommended to use in red clover breeding for creation homozygous lines and multilinear varieties with high and sustainable seed productivity.
