DEVELOPMENT OF SELF-POLLINATED LINES FOR WINTER RYE (SECALE CEREALE L.) HYBRID CULTIVARS BREEDING
N the article, the basic results of self-fertile winter rye lines development with the use of different methods are stated. The method of self-fertility genes introduction into rye populations, the method of inbred lines development with the use of F<sub>1</sub> heterosis hybrids are described. The necessity of working out of anther technology culture in vitro for the development of rye double haploids is noted. The practical use of the developed inbred lines in rye breeding for heterosis is described.
