| description | Rice can form not only white, but also red, brown and black kernels. In black rice, pericarp kernels contain anthocyanin, which has an antioxidant effect and is beneficial to human health. The current paper is devoted to the development of new rice lines with black pericarp based on the hybrid Svetly × Mavr. The purpose of the work is to develop new forms of rice with anthocyanin pericarp by a hybridization of varieties with white and black kernels, a genetic analysis of a number of quantitative traits and by a selection of the best variants with compact vertical black-kernel panicles to use them in future breeding work. There has been conducted a genetic analysis of varying quantitative traits affecting the rice productivity. The cleavage by a pericarp color was carried out according to the type of recessive epistasis in a ratio of 9 : 3 : 4. The black color of the pericarp was formed in the presence of two dominant genes Pb and Pp in the genotype, the brown color was due to the Pb gene, the white color was due to the rest combinations of genes. The traits “plant height” and “number of spikelets per panicle” of the hybrids F2 and F3 were inherited by the type of superdomination of large values of the trait controlled by two loci, the interaction of which resulted in transgressive forms. According to the traits “panicle length” and “1000 kernel weight”, there has been identified intermediate monogenic inheritance and two-peaked characteristic frequency distribution curves. There have been identified rice forms with black pericarp color, combining the optimal values of the traits “plant height”, increased “panicle length”, “number of spikelets per panicle” and “1000 kernel weight”. On its basis there has been also developed an initial material for practical breeding. The study was carried out in 2018–2020 on the fields of the EP “Proletarskoye” of the Rostov region. |
