Leonova K. Morphological and adaptive genetic peculiarities of inheritance and correlations of useful productivity features for heterotic selection of carrots.

Object: heterosis breeding carrots, adaptability parameters for yield and yield structure elements, the degree of dominance symptoms. Objective: To study the morphological and adaptive genetic characteristics of different accessions of carrot genetic origin and creation of the Raman-capable line for heterosis breeding on the basis of CMS. Novelty: combining different methods of estimating the parameters of plasticity and stability, established norms of reaction of different genotypes of carrot eco-geographical origin of the influence of biotic and abiotic factors of the environment and highlights the sources of new genetic traits earliness, yield and marketability, quality of root crops. Results: The studied general and specific combining ability of new istochnikovhozyaystvenno valuable features, isolation from the global gene pool of carrots. The degree of dominance of the signs and effects of heterosis in hybrid carrot harvest on the elements of the structure. Optimized methods selektsiyno-seed the process of creating a linear material by using a carrot rostreguliruyuschih substances. Have developed an improved method for creating fertile lines-fixers sterility and their CMS counterparts. Found new original forms drought-and heat-resistance.
