“…The PCA analysis is a data reduction technique for analysing interdependence that seeks to minimize diverse and complex associations between collections of measured traits by revealing similar characteristics or elements that interconnect independent variables (16). Previously multivariate analysis in mustard was studied by (17). In their work, (18) used 33 genotypes to produce 5 groups and while evaluating 31 Brassica juncea genotypes for the purpose of choosing genetically diverse parents using Mahalanobis D 2 analysis.…”

Brassica juncea is an important industrial and commercial oilseed crop grown primarily in India. This study aimed to assess 56 genotypes of Indian mustard to quantify genetic diversity, which aids the breeder in identifying genetically divergent parents to evaluate the proportional contributions of various components towards overall divergence. All the 56 Indian mustard genotypes were tested in RBD with three replications for 2 consecutive years i.e. 2016-17 and 2017-18 during the rabi season. Observations were recorded for 11 yield and its attributing traits. The findings revealed that height up to first branching, aphid count, penetration force and seed yield per plant had maximum PCV and GCV signifying that genetic factors have a greater impact on the inflow of these traits. Height up to first branching, secondary branches per plant, primary branches per plant, siliquae per plant, aphid count and 1000 seed weight had strong heritability combined with GA as % of mean. These indicate that the traits were controlled by additive gene action. Seed yield per plant was significantly correlated with penetration force and siliquae per plant. As a result, it's reasonable to predict that improving these traits by selection, could lead to significant yield gains. Four of the eleven PCs had eigen values greater than 1.0, accounting for 69.94% of the variance. PC I, which explained 30.31% of the overall variance. Mahalanobis D2 statistics revealed considerable genetic diversity among the genotypes. 56 genotypes were distributed into 7 clusters. This is anticipated that genotypes within a cluster are almost genetically related to one another. Cluster VII and II showed maximum inter-cluster divergence. From a breeding perspective, a divergence analysis revealed that genotypes like SKJM-05, RNWR-09-3, RW-351, B-85, DRMR-4001, RGN-386, TM52 276 and SKM-1313 can be selected as genetically divergent parents for hybridization to obtain desirable segregants.

“…Increasing the α‐T content would make rapeseed a source of functional foods, whereas increasing the content of the γ‐T homologue would improve the oxidative stability of rapeseed oil . Several studies have demonstrated a potential for selection of a DH line of winter oilseed rape with better morphological and biochemical traits than its parental forms . The studied population of DH lines obtained by inversely crossing the DH line black (DH H 2 ‐26) × yellow seed (DH Z‐114) winter oilseed rape was divided into five groups with respect to seed colour (Table ).…”

The obtained DH lines population of oilseed rape is characterized by high heritability coefficients for α-T, β-T, γ-T, total-T and PC-8 levels, which indicates a greater influence of genotype than the environment on the content of these compounds. Among all studied doubled haploids, seven DHs were selected which were characterized by stable contents of α-T, β-T, γ-T, δ-T and total-T with the simultaneous stable content of PC-8. © 2017 Society of Chemical Industry.

“…Numerous DH populations of winter oilseed rape obtained from an isolated microspore culture (Cegielska-Taras et al, 2002) have been widely used in various statistical researches, for example, to study the influence of environmental conditions on the stability of important yield components and the transgression effects of advantageous traits (Szała et al, 2015b).…”

Haploids and doubled haploids (DHs) have been produced in Brassica ssp. using anther or isolated microspore cultures. Since 1982, when Lichter developed a method of isolated microspores culture, this technique has been constantly improved and modified. Haploids and DH of Brassica napus have been extensively used in genetic studies, such as gene mapping, location of quantitative trait locus, marker / trait association studies, and genomics. Furthermore, the oilseed rape haploid induction technique can nowadays be efficiently combined with several other plant biotechnological techniques, enabling several novel breeding achievements, such as mutation breeding, the breeding of hybrid varieties, genetic transformation, and resynthesis of B. napus. The development and improvement of in vitro androgenesis of oilseed rape allowed DH populations to be obtained on a large scale. Today DH lines are used in the genetic analysis of quantitative traits and to analyze the impact of the environment on the yield and quality of the seeds. Currently, DH technology has become more efficient and hence can be widely applied in winter oilseed rape breeding. Additionally, DH technology is used to shorten the process of breeding new varieties. An open pollinated B. napus cv. Monolit (Plant Breeding Strzelce Ltd., Co.) is the first Polish winter oilseed rape variety obtained using DH technology. The breeding cycle of this variety is about four years shorter compared to a classical breeding program. The second Polish cultivar obtained using DH technology, cv. Brendy (Plant Breeding Smolice Ltd., Co.) was developed in a similarly short period. In the breeding of new oilseed rape hybrid varieties, homozygous restorer lines are also exploited. Our basic research used oilseed rape DH technology with a focus on improving the qualitative traits of oilseed rape and is presented here, based on the major researches conducted worldwide as well as on the results obtained at the Plant Breeding and Acclimati
