Використання ліній-носіїв крохмаль-модифікуючих мутацій в селекції цукрової кукурудзи на продуктивність

Abstract

The possibility of expandion of the sweet corn’s useful genetic diversity by means of hybridization between inbreds- carriers of mutation su₁ and the inbreds- carriers of other starch- modifying mutations was established. It has been determined that the inbreds  with the identical allelic state of endosperm structures' genes very much differ for the productivity and the elements of its structure as well as the combining ability for these traits. The best sources and donors of productity traits were identified and the series of practically valuable top crosses was obtained
