Sampling Problems

The response of three spring cultivars of oilseed rape to five levels of nitrogen fertilizer (0 to 200 kg/ha) was studied during 1978–9 (Scarisbrick, Daniels & Alcock, 1981). Sampling problems, practical difficulties of measuring yield components, and the high co-efficients of variation for these data were discussed. During the course of further investigations on the winter cultivar Jet Neuf (established on approximately 75000 ha in the U. K. during 1980–1) within-plot variability for plant weight was assessed in order to indicate the size of sample necessary to compare treatment means.

Growth Development

SUMMARYThe growth and development of single plants of oil seed rape, variety Zollerngold, are described quantitatively and particular attention paid to the sequence and pattern of flower and pod production on the different inflorescences. The period of flower opening over the whole plant spanned an average of 26 days and more than 75% of the pods which were retained to maturity were formed from flowers which opened within 14 days of anthesis. Most of these flowers were found on the terminal raceme and on the basal and middle regions of the axillary inflorescences arising from the uppermost three nodes.

SummaryThe relationship has been investigated between the yield of oil-seed rape (Brassica napus L.) plants and (a) the proportion of podless stalks, (b) the proportion of pods infested by seed weevil larvae and (c) the effect of removing a proportion of buds and pods. Plants compensated for damage and, although late removal of buds or pods sometimes caused greater yield loss than early removal, only plants with more than 60% podless stalks or buds removed had diminished yields. The numbers of podless stalks per plant increased with plant size. Removal of 60 % of a plant's pods caused no yield loss; in the field a maximum infestation of only 25% of the plant's pods with seed weevil larvae occurred. The results are discussed in relation to damage by pollen beetles (Meligethes aeneus Fab.) and seed weevils (Ceutorhynch.ua ossimilis Payk.)

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.
