Effect of Genotype × Environment Interaction for Seed Traits in Winter Oilseed Rape (Brassica napus L.)

Abstract

Brassica napus (L.), winter oilseed rape (WOSR) or canola, is one of the most important oilseed crop species of the moderate climate zone. Improving the seed quality and yield makes the main target in breeding programs worldwide. In this study, we examined the genotype-by-environment (G×E) interaction with respect to six seed traits among 25 WOSR genotypes. The plant material included the registered canola cultivars, our newly developed mutant breeding lines and the Ogura F1 hybrids and their parental components, in addition to our domestic breeding lines including two semi-resynthesized (semi-RS) lines. The 25 genotypes were examined in field trials at two locations, in three growing seasons. Seed oil and protein content, total glucosinolates (GLS) content in seed meal and C18 unsaturated fatty acid (oleic, linoleic and linolenic) composition in seed oil were examined. The additive main effects and multiplicative interaction (AMMI) analyses revealed significant effects of both, genotype (G) and environment (E) as well as the G×E interaction regarding the analyzed seed traits. In our study, two Ogura F1 hybrids, a CMS line and a new high oleic mutant breeding line revealed high stability and good average values for most of the analyzed seed traits, thus making a valuable source of starting materials for further improvement.

“…On the other hand, GE interactions were significant for two of the three traits of interest (seed yield and pod per plant) and explained 18.1% of the variation in seed yield and 11.3% for pods plant −1 . Recent research assessing GE interaction for canola has mostly focused on seed quality traits (Bocianowski et al., 2019; Liersch et al., 2020). However, Załuski et al.…”

However, Załuski et al (2020) reported significant environmental, genotypic, and GE interactions effects on seed yield and 1000-seed weight in camelina [Camelina sativa (L.)], a member of the Brassicaceae family.…”

Trait profiling and genotype selection in oilseed rape using genotype by trait and genotype by yield*trait approaches

“…Oilseed rape ( Brassica napus L.) is the second worldwide major supplier of edible oil, after soybeans (Liersch et al, 2020 ). The oilseed rape grain production reached almost 71 million tons during the 2018–2019 cropping season (Liersch et al, 2020 ). In Iran, however, oilseed rape is the first major oilseed cultivated crop (Amiri Oghan et al, 2016 ).…”

“…The factors affecting oil yield could be oil content, seed water content, and pressing technology [40][41][42]. Oilseed content in general is affected by the interaction between genetic and environmental factors [43,44]. The existence of seed water content affects the oil quality (clearness of the oil yield) [42], while the pressing technology could affect the oil yield due to differences in the pressure strength [41].…”
