Fertility Restorers

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

Hybrid Group

The performance of six isogenic pairs of male fertility restored, hand-crossed, summer rape (Brassica napus L.) hybrids, in the mur and nap cytoplasms, were investigated in four Manitoba environments. Hybrids in both cytoplasms exhibited high-parent heterosis for seed yield, total dry matter (TDM) and, to a lesser degree, harvest index (HI). Negative high parent heterosis for days to flowering, days to maturity, oil concentration and protein concentration was observed. Combined over hybrids within cytoplasms, the mur and nap cytoplasmic hybrid groups differed in oil concentration in all environments, and in protein concentration in one of four environments. Similarly, the mur hybrid group was lower-yielding and had lower TDM, HI and oil concentration, but higher protein concentration than the nap hybrid group. Even though there are some biological costs associated with the mur cytoplasm, especially for oil concentration, it appears that the mur cytoplasmic male sterility (CMS) system has good potential for use in summer rape hybrid cultivar breeding and commercial hybrid seed production, since hybrids in the mur cytoplasm display heterosis for many traits in absolute terms.

No male sterile plants were found in the F1 progeny from crosses between a Diplotaxis muralis cytoplasmic male sterile (mur CMS) semi-winter habit rape (Brassica napus L.) A-line and 101 genetically diverse summer rape cultivars or strains. The frequency of occurrence of mur CMS system maintainer genotypes in summer rape is very low, possibly zero. Key words: Mur CMS system; Brassica napus L.
