“…However, transgressive effects for protein content occurred only in the yellow-seeded DH lines. Similar results were obtained by Wolko et al [35], indicating that selection for a lighter colour could lead to higher protein content in seeds.…”

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.

“…Against this background, the variability we observed within the DH lines seems high (18.1-26.4% in the first year and 20.0-26.6% in the second year of the study). Higher variability for seed protein content was observed by Chao et al [38] and Wolko et al [35] in mapping populations.…”

“…The mean content of neutral detergent fiber (NDF) in the yellow-seeded Z114 line was 17%, while in black-seeded M305 line it was 23%. The mean content of acid detergent fiber (ADF) was about 10% in the Z114 line and 17% in line M305 [18]. At the same time, yellow-seeded lines may be characterized by a lower yield [13] and a lower thousand-seed weight, which can be observed in the yellow-seeded parent of our DH population (3.97-4.81 g according to the year of research), while the thousand-seed weight of the M305 line ranged from 4.97 to 5.52 g [18].…”

“…The seed coat color was determined on the same seed samples with the Hunter Labs spectrocolorimeter (Colorflex) and classified using a 0 (black) to 5 (yellow) scale [17]. The results of detailed analyses of the content of oil, protein, fiber (ADF and NDF), and glucosinolates in the seeds of the studied population in two growing seasons (2015/2016 and 2017/2018), investigated with a near-infrared reflectance spectroscopy (NIRS), have been previously published in Wolko et al's [18] study. The studied DH population was also sequenced and the obtained SNPs markers were used for QTL genetic mapping to search for loci associated with the biochemical components of seeds and seed coat color.…”

Statistical Multivariate Methods for the Selection of High-Yielding Rapeseed Lines with Varied Seed Coat Color

A crucial aim for rapeseed breeders is increasing the seed yield through improving yield- and silique-related traits. In this research, traits including the number of seeds per silique, silique length, silique width, and thousand-seed weight combined with seed coat color were investigated. Yellow-seeded lines of oilseed rape have a thinner seed coat, lower fiber content, and higher protein and oil content than traditional varieties. Hybrids of yellow- and black-seeded Brassica napus, which combine the advantages of both types of seeds, are tested for their suitability in breeding. Therefore, the aim of this study was to assess a population of 78 doubled haploid lines with different seed coat colors to select genotypes connecting a light color of seeds with good yielding characteristics. Multivariate methods such as analysis of variance, correlation analysis, regression analysis, canonical variate analysis, Mahalanobis distances, and estimation of gene effects were used. The results showed that all tested genotypes were significantly different regarding all five studied traits. The multidimensional analyses gave an accurate overview of the relationship between the examined features. The color and weight of seeds were considered the most important for breeding rapeseed with better seed properties. Although a negative correlation between these two characteristics occurs quite commonly, it was not present in our plant material, which allowed us to select lines with a-light seed color and high thousand-seed weight, which is a significant achievement. As a result, two doubled haploid lines were chosen as valuable breeding material for creating oilseed rape varieties with improved biochemical characteristics of seeds.

“…e results suggest a large genetic variation in these traits and the interrelationships among them. e analysis of heritability and gene effects on the studied traits allowed the estimation of the genetic background of these traits (Wolko et al, 2020). e same population (DH M305 × DH Z114) of 78 DHs was used in the QTL mapping analysis to explain the genetic basis of the characteristics affecting the quality of oilseed rape meal: protein, fiber, GLS, and seed coat color.…”

Diverse processes leading to doubled haploid (DH) plant production, such as microspore embryogenesis, gynogenesis, and distant hybridization followed by genome elimination, are based on the unique ability of plant cells to form haploid embryos without fertilization. All of these are possible because of various in vitro culture systems that enable the growth and development of tissues or single cells outside of the parental organism. The possibility of re-directing cell development from its original pathway to embryogenesis brings several benefits to many research areas, but the most important is the possibility of its implementation in breeding programs. This review summarizes the achievements of Polish research groups in studies of the mechanisms of haploid/DH embryo development and demonstrates the practical applications of these systems in basic studies and plant breeding. It shows the results of studies on economically important crops including barley ( Hordeum vulgare L.), oilseed rape ( Brassica napus L.), triticale (× Triticosecale Wittm.), oat ( Avena sativa L.), rye ( Secale cereale L.), sugar beet ( Beta vulgaris ssp. vulgaris L.), and some vegetable species, including carrot ( Daucus carota L.), onion ( Allium cepa L.), red beet ( Beta vulgaris L.), and members of the Brassicaceae.
