SEARCH OF FERTILITY REGULATORS FOR POLIMA TYPE CYTOPLASMIC MALE STERILITY OF SPRING RAPE (Brassica napus L.) AND ASSESSMENT OF THEIR QUALITY

One of the prior directions in modern rapeseed breeding is making heterotic hybrids. Seed production most hybrids F1 used are often carried out by two types cytoplasmic male sterility, there Polima and Ogura. At All-Russian Rapeseed Research Institute, fertility restorers on sterile cytoplasm were made estimated for main valuable characteristics biochemical properties. The purpose study was to create reducing agents necessary obtaining highly productive type sterility (CMS). object research 56 varieties Brassica napus L., which chosen 2013. setting experiments, observations, records analyzes using field plot technique, methodology method statistical data processing. It noted that had more productivity than parental forms standard (Ratnik Rif). Promising identified, ensured complete restoration lines with CMS type. agent LHR-1 practical interest creation CMS.
