In this study, performed in the western part of the state of Paraná, Brazil, two self-fertile hybrid commercial rapeseed genotypes were evaluated for yield components and physiological quality using three pollination tests and spanning two sowing dates. The treatments consisted of combinations of two rapeseed genotypes (Hyola 61 and Hyola 433), three pollination tests (uncovered area, covered a...

Assessing the level of genetic diversity within a germplasm collection contributes to evaluating the potential for its utilization as a gene pool to improve the performance of cultivars. In this study, 45 high-quality simple sequence repeat (SSR) markers were screened and used to estimate the genetic base of a world-wide collection of 248 rapeseed (Brassica napus) inbred lines. For the whole co...

Genomics-based prediction of hybrid performance promises to boost selection gain. The main goal of our study was to investigate the relevance of additive, dominance, and epistatic effects for determining hybrid seed yield in a biparental rapeseed population. We re-analyzed 60,000 SNP array and seed yield data points from an immortalized F2 population comprised of 318 hybrids and 180 parental li...

Except for the events RT73, MS8, RF3, and T45, event-specific detection methods for most commercialized genetically modified (GM) rapeseed varieties have not been established, and as a result, the enforcement of genetically modified organism labeling policies has been hindered. The genetically modified rapeseeds, MS1xRF1 and MS1xRF2, are 2 of 11 approved GM-rapeseed varieties for commercializat...

This article presents the results of research on production mutant doubled haploids turnip rape (Brassica rapa L.ssp.Oleifera), as well its interspecies hybrids with rapeseed napus). An  immature embryo culture  was used to increase productivity inter-specific hybridization. Studies have obtained interspecific rapeseed. The largest number plants observed in where mother plant Furtherm...

One of the prior directions in modern rapeseed breeding is making heterotic hybrids. Seed production most hybrids F1 used are often carried out by two types cytoplasmic male sterility, there Polima and Ogura. At All-Russian Rapeseed Research Institute, fertility restorers on sterile cytoplasm were made estimated for main valuable characteristics biochemical properties. The purpose study was to ...

The utilization of heterosis in rice, maize and rapeseed has revolutionized crop production. Although elite hybrid cultivars are mainly derived from the F1 crosses between two groups of parents, named NCII mating design, little has been known about the methodology of how interacted effects influence quantitative trait performance in the population. To bridge genetic analysis with hybrid breedin...

The study presents the results of genetic diversity estimation winter rapeseed by molecular analysis and determination polymorphism with morphological traits. aims to determine hybrids SSR markers marker characteristics. Twelve which were examined within DUS testing their 24 hereditary components studied in 2021–2022. genotypes was carried out 2021. It determined that majority are characterized...

Combining ability is crucial for parent selection in crop hybrid breeding. The present investigation and results had revealed the underlying genetic factors which might contribute in adequate combining ability, further assisting in enhancing heterosis and stability. Here, we conducted a large-scale analysis of genomic variation in order to define genomic regions affecting the combining ability ...
