“…A positive correlation between TSW and SL was also observed with moderate coefficients in Li et al (2014) research. A negative correlation between TSW and SS were found by Xing et al (2014). The same correlation was also noticed in our research in 2014/15 growing season.…”

Rapeseed breeding programs are focused mainly on improving plant potential and seed yield. One of the ways to improve seed yield in oilseed rape is heterosis, which is hybrid vigor that results in a greater biomass, increased seed yield, and faster development. The purpose of this study was to estimate yield-related trait heterosis for single cross and three-way cross hybrids of winter oilseed rape (Brassica napus L.). A population of 60 doubled-haploid (DH) lines and two generations of hybrids were evaluated in field trials to assess six yield-related traits: plant height, number of branches per plant, number of siliques per plant, silique length, number of seeds per silique, and thousand seed weight. Heterosis effects for each trait were estimated by a comparison of the particular hybrid with: (1) the trait mean over both parents—mid-parent heterosis and (2) to the value of better parent—best-parent heterosis. Traits with clear positive heterosis and traits with varied heterosis were observed in this study. For the first group, we include plant height, silique length, and the number of seeds per silique—a large number of hybrids expressed significant positive heterosis for these traits, independent from the year of observations and the type of hybrid. For the second group, with varied heterosis, we can include the number of branches and siliques per plant and thousand seed weight. For these traits, hybrids exhibited both positive and negative significant heterosis, without a clear pattern for the years and types of hybrids.

“…However, in the F 2 generation derived from reciprocal cross F 1 seeds, the difference in oil content disappeared. Also in the study by Xing et al (2014), the contribution of the maternal parent was slightly higher than that of the paternal parent with regard to the fat content. Other studies have indicated that embryo genetic effects, cytoplasmic effects and maternal effects as well as genotype×environment interaction effects (Wu et al 2006;Variath et al 2010) simultaneously controlled oil content in oilseed rape.…”

Here we present a study on the genetic effects of agronomic and seed quality traits in double haploid (DH) populations, which were developed by microspore culture from reciprocal F 1 hybrids produced between cultivar Californium and DH W-15. Each of the populations consisted of 25 DH lines. The field experiments were conducted in a randomized complete block design with three replications during three growing seasons. Field observations were recorded on seed yield and its structure: the number of branches and pods per plant, the number of seeds per pod, the 1 000 seed weight, the content of fat in the seeds, and three unsaturated fatty acids (oleic, linoleic, linolenic) in the seed oil. In order to investigate the influence of cross direction on the studied traits, parental effects were evaluated on the basis of differences between reciprocal DH populations. The maternal effect was revealed for the number of seeds per pod and the effect of the paternal form on linolenic acid content. The occurrence of transgression effects also depended on the direction of crossing and this was particularly noticeable in terms of the number of seeds per pod. The use of multivariate statistical methods allowed for the simultaneous characterization and grouping of tested lines in terms of several traits. Graphic images of the distribution of DH lines in the space of the two first canonical variates showed a great variation between the two reciprocal populations, both in terms of yield and its components, as well as fat and those unsaturated fatty acids.

“…Amiri-Oghan et al (2009) observed that this variable is controlled mainly by additive effects. However, according to Xing et al (2014), grain yield per plant is mainly controlled by the additive and epistatic effects. In this context, it can be inferred that the absence of heterosis is not decisive absence of dominance.…”

Biplot analysis was conducted to estimate the combining ability of ten parental genotypes using 7×3: Line×Tester data of 21 F 1 hybrids in (Brassica napus L.) for seed yield and oil content. The data obtained from all the three replications of experimental material in randomized complete block design were subjected to analysis of variance to check the null hypothesis of the equality of means. Significant differences (P≤0.01) were found among the parents, F 1 hybrids and Line×Tester interaction for the variables seed yield plant -1 and oil content. The genotypes CA-4 and DH-6 were the promising for seed yield plant -1 (36.8 g) and oil content (51.2%), respectively. Among the hybrids DH-3×CA-4 and DH-4×CA-4 were best for seed yield plant -1 (51.1 g) and oil content (52.1%). The GGE biplot displayed DH-8 and DH-2 as the best general combiners for seed yield and oil content, respectively. The best specific combiner for seed yield plant -1 was DH-3 whereas; for oil content DH-2 was ranked first. Among the testers CA-5 and CA-4 were ranked first on the basis of GCA for seed yield plant -1 and oil content, respectively. The GGE biplot graphic allowed a rapid and effective overview of General Combining Ability (GCA) and Specific Combining Ability (SCA) effects of the inbred lines; best lines and tester, as well as their performance in crosses.
