Field trials were conducted in the years 2017–2019 at the Małopolska Plant Breeding in the Plant Breeding Stations in Polanowice, Nieznanice and Palikije. The trials were designed to determine the yield of some timothy genotypes in the context of chemical composition under different habitat conditions. The present evaluation of the strain quality shows a high potential for breeding. The analyzed genotypes produced high dry matter yields, which differed by as much as 53%. The experimental plots also differed in the crude protein content, which varied from 104.5 to 230.1 g kg−1 d.m., depending on the crop and year of harvest. For crude fiber, these values ranged from 173.9 to 274.8 g kg−1 d.m., depending on the crop and harvest year. The analysis of the mineral composition also revealed significant large variation.

Genetic Variability in a Population of Oilseed Rape DH Lines Developed from F1 Hybrids of a Cross between Black- and Yellow-Seeded DH Lines. II. Seed Quality

One of the main reasons for oilseed rape breeding is to improve the quality and composition of seeds by increasing fat and protein content, and to reduce dietary fibre. We attempted to obtain such varieties by crossing two DH lines of winter oilseed rape of different origin, H2-26 and Z-114, which have black and yellow seeds, respectively. The cross was followed by in vitro androgenesis, resulting in a population of 44 DH lines that were studied in a field experiment over two seasons. The following characters of the resulting seeds were analysed: fat, protein, neutral detergent fibre, acid detergent fibre, glucosinolate content and seed colour. The main objective was to check the variability of the DH lines obtained from F1 hybrid black- and yellow-seeded oilseed rape. The range of variability of the DH lines significantly exceeded the range of variability of the parental lines for all traits. These experiments showed that by choosing the appropriate parental genotypes of oilseed rape it is possible to break the negative correlation between protein and fat content. The high level of heritability of traits related to seed quality raises the possibility of improving breeding lines through selection based on phenotype.

“…Specific combining ability (SCA) is a type of combining ability that is based on nonadditive allelic effects [8]. It is determined by the difference between the trait value in a given cross relative to the expected value determined on the basis of overall combining ability [9]. Specific combining ability plays a key role in plant breeding and is important for obtaining desired traits and improving yields.…”

Meta-Analysis of Influence of Diversity of Parental Forms on Heterosis and Specific Combining Ability of Their Hybrids

An important stage in any breeding activity is selection of suitable individuals for further breeding. Thus, the main goal of breeders becomes such a selection of parental forms that leads to the consolidation and maximization of the value of traits of significant utility and economic importance. Heterosis and specific combining ability are very important parameters in plant and animal breeding. The ability to predict their value and relevance could significantly shorten the breeding process. One way to predict the effects of heterosis and specific combining ability is to select parental forms for crosses. This selection can be made on the basis of variation in parental forms. An analysis was made of publicly available data that contain information about the effects of heterosis, the effects of specific combining ability, and phenotypic and genetic diversity of parental forms. Preliminary studies show that the best approach for obtaining favorable hybrids would be selection of parental forms that are very genetically diverse while being phenotypically equal.
