“…Hence, it is necessary to develop new varieties of rapeseed with high seed yield. To increase the yield, study of direct and indirect effects of yield components provides the basis for its successful breeding program, and hence, the problem of yield increase can be more effectively tackled on the basis of performance of yield components, and selection for closely related characters (Friedt et al, 2007;Aytac et al, 2008;Marjanovic-Jeromela et al, 2009). The multivariate analysis, particularly factor and cluster analyses, are utilized for evaluation of germplasm for various traits in a large number of accessions.…”

“…Without a broad base of heterogeneous plant material, it is impossible for plant breeders to produce cultivars that meet the changing needs regarding adaptation to growing conditions, resistance to biotic and a biotic stresses product yield or specific quality requirements (Friedt et al, 2007). Therefore, the most efficient way to farther improve the performance of crop varieties is to access to large diverse pool of genetic diversity.…”

This study was carried out to assess the genetic diversity in 48 genotypes and accessions using eight Amplified Fragment Length Polymorphism (AFLP) primer-pairs. The eight selected AFLP primer-pairs generated a total of 150 polymorphic loci. Using the generated AFLP data, the Un-Weighted Pair Group Method with Arithmetic Average (UPGMA) ordered the genotypes into six groups based on Dice similarity coefficient. The range in taxonomic distance was from 0.23 to 1.0. Each cluster was found to have genotypes and accessions from different regions and climate and sometimes different continents. The size range of the loci ranged from 87-662 bp. Great variation between the genotypes and accessions in the different cluster could be of high value as the genetically diverse okra genotypes represent a potentially valuable source for improved pathogen and pest resistance.

“…Rapeseed is grown for animal feed, vegetable oil and green diesel [2], but the production and use of green diesel in Pakistan is fiction of today and fact of tomorrow. Other products such as lubricants, hydraulic oils, detergents, soaps and recyclable plastics also depend on rapeseed [3]. Rapeseed residue known as meal, having 38-44% protein is a useful animal feed and also fertilizer for many crops [4].…”

A diallel analysis study for estimating the pattern of inheritance and heritability of oil content and quality attributes in Rapeseed (Brassica napus L.) was carried out at The department of Plant Breeding and Genetics, The University of Agriculture, Peshawar during crop season 2011-2012. Four diverse parents viz. G2, G4, G6 and G9 of Brassica napus L were used in a full diallel fashion during the 1 st year of experiment (Crop season 2010(Crop season -2011. All the parents along with their F1 hybrids were evaluated in field condition in the 2 nd year of experiment (Crop season 2011(Crop season -2012 in randomized complete block design. Differences among these lines for Oil content, Protein content, Glucosinolate content, Erucic acid and Linolenic acid were found highly significant (P ≤ 0.01), except Oleic acid for which non-significant differences were observed, so oleic acid was excluded from diallel analysis. Additive-dominance model was found fully adequate for Oil and Protein content, whereas it was partially adequate for the remaining traits under study. After diallel analysis results, highly significant additive (a) and non-additive (b) variances for characters such as Oil content, Protein content, Glucosinolate content and Erucic acid, while for Linolenic acid non-significant additive variance was observed. Estimation of genetic parameters showed higher magnitude and significance of non-additive component for all the seed quality traits except erucic acid, for which additive component was higher in magnitude. Graphical analysis showed overdominance for all of the parameters except erucic acid for which partial dominance was observed. Average degree of dominance value for Oil content (1.344), Protein content (1.636), Glucosinolate content (1.145) and Linolenic acid (4.156) also showed the importance of overdominance gene action responsible for all these studied seed quality traits, as it was greater than one, while for Erucic acid (0.803) it was lower the one showing partial dominance. For all the studied parameters, high broad sense heritability (0.70-0.96) and low narrow sense heritability (0.05-0.683) was estimated, showing the low role and magnitude of additive gene action and suggests selection for these traits in the later segregating generation/s.
