Selection of superior L. hybrids by integrated graphical and numerical diallel analysis by yield×traits: Using hayman and biplot diallel approaches.

Improving yield via assessment of different yield-related genetic parameters specifically with the challenges of yield × traits combination is a prominent issue for plant breeders. A graphical and numerical description of diallel analysis by yield × traits with the novelty of the parent selection with desirable genetic architecture in rapeseed was illustrated via Hayman and biplot approaches. Eleven divers' parents and their F offspring, achieved via a complete diallel mating fashion, were evaluated under field conditions based on randomized complete block design replicated thrice throught 2018-2020.

Enhancing yield and oil content in oilseed rape hybrids: Insights from line × tester and SIIG approaches.

Background: The production of high-oil-yielding hybrid varieties is a primary objective in oilseed rape ( L.) breeding programs. Biometric genetic experiments such as line × tester provide valuable insights into the genetic structure of traits associated with high oil yield.

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

Selection and breeding for high-yielding in oilseed rape have always been one of the leading objectives for oilseed rape breeders. This process becomes more complicated when all quantitative traits are considered in selection in addition to grain yield. In the present study, 18 oilseed rape genotypes along with 2 check cultivars (RGS003 and Dalgan) were evaluated across 16 environments (a combination of 2 years and eight locations) in the tropical climate regions of Iran during 2018-2019 and 2019-2020 cropping seasons.

Phenotyping new rapeseed lines based on multiple traits: Application of GT and GYT biplot analyses.

The selection based on multiple traits enhances the crop cultivars merit to farmers. In this regard, 19 breeding lines as well as two commercial cultivars were studied using a randomized complete block design (RCBD) with three replications in three locations during the 2020-2021 growing season. In this study, to identify the association among different traits and to select the best rapeseed lines based on multiple traits, genotype × trait (GT) and genotype × yield × trait (GYT) biplot analyses were used.
