Перспективные экспериментальные гибриды рапса ярового (Brassica napus L.), созданные с использованием системы ЦМС типа Polima

Abstract

One of the prior directions in spring rapeseed breeding is development of heterotic hybrids. Seed growing of the most hybrids F1 used in production are often carried out by two types of cytoplasmic male sterility, they are polima and ogura. At the Lipetsk Rapeseed Research Institute, fertility restorers on sterile cytoplasm were made and estimated for the main valuable traits. The purpose of the research was to develop effective restorers, which are necessary for obtaining of highly productive hybrids on the Polima type cytoplasmic male sterility (CMS). The object of research was 56 varieties of Brassica napus L., which were selected in 2013. It is noted that hybrids F1 were more productive than the parental forms and the standards (the varieties Ratnik and Rif). The restorer line LHR-1 is of practical interest for the development of hybrids on the Polima CMS.
