Genetic variability and regression analysis for yield and quality traits in Brassica napus

An experiment was conducted to estimate the genetic variability and regression analysis for yield and quality traits in a set of eight brassica genotypes in a randomized complete block design with three replications at The University of Agriculture Peshawar, during 2011-12 cropping season. Significant genetic variability was recorded among genotypes for plant height, pods main receme-1, pod length, seed yield plant-1, 1000-seed weight, seeds pod-1, oil content, protein content, glucosinolate content, erucic acid content, oleic acid content and linolenic acid content except for primary branch plant-1 and pods plant-1 which showed non-significant differences. Genotypes, AUP-401, AUP-402, AUP-404 and AUP-407 showed potential performance for glucosinolate content (55.1 µmol g-1), seed yield plant-1 (23.93 g), pods plant-1 (268.83), protein contents (21.1 %), erucic acid contents (42.7 %) and oil contents (53.3 %). Seed yield plant-1 was taken as a dependent variable to study the effects of many morphological yield traits on it. Branches plant-1, pods main raceme-1, pods plant-1, and seed pod-1 showed a positive effect on seed yield plant-1, while 1000-seed weight, pod length, and plant height showed a negative effect on seed yield plant-1. Seed yield plant-1 as an independent variable showed a negative effect on oil content. Protein content as an independent variable showed a positive effect on erucic acid content, while oil contents as independent variables show a negative effect on protein contents, respectively. The developed germplasm could be used in the upcoming brassica breeding programs to release high yielding, disease resistance, stress tolerance, and insect resistance varieties, which will eventually upsurge the productivity and decrease the gap between demand and domestic production of the brassica crop.

Brassica Napus L

Doubled haploid (DH) self-incompatible (SI) regenerants with improved seed quality were derived after two improvement crossing cycles with different “00” quality donors. The original genetic resource of recessive sporophytic SI was characterised by a high glucosinolate (GSL) and erucic acid content. SI regenerants of satisfactory seed quality parameters were obtained from the second cycle of crossing. Total number of derived SI plants was 87, i.e. 38.2% out of 228 obtained fertile doubled haploid regenerants developed in 2004. Nine plants out of the analysed 45 SI DH regenerants had the erucic acid content lower than 2%. Five out of these nine plants, which were analysed by HPLC method, had the glucosinolate content lower than the limit 18 µmol/g at 9% seed moisture. The method based on the spraying of inflorescences with 5% NaCl to enable reproduction of SI lines was verified.

Wild Mustard

Research was conducted at two sites near Brandon, Manitoba, in 1990 and 1991 to determine the influence of time of removal of wild mustard from triazine-tolerant (TT) or triazine-susceptible (TS) canola and the effects of wild mustard seed contamination on canola seed yield and oil characteristics. Wild mustard was removed by either cyanazine or ethametsulfuron at the two-to-four-leaf or the four-to-eight-leaf stage of wild mustard in each of six canola cultivars. Wild mustard decreased harvested seed yield of canola, and the presence of wild mustard seed in harvested canola seeds increased meal glucosinolate content compared with that of the weed-free check. Canola yield was greater than that of the untreated check when wild mustard was removed at either the two-to-four-leaf or the four-to-eight-leaf stage. Canola seed yield was reduced compared with that of the weed-free check when wild mustard was allowed to compete with canola until the four-to-eight-leaf stage. Meal protein content was decreased by either wild mustard competition or the presence of wild mustard seed in the samples in 1991 but not in 1990. Canola seed samples contaminated with wild mustard seed had reduced oil and oleic acid content at both sites. Wild mustard competition reduced canola oil and oleic acid content of the two TT cultivars more than it did those of TS cultivars. The presence of wild mustard seed (but not interference from wild mustard) increased the linolenic and erucic acid content of the extracted oil.

Somaclonal Variations ◽

Low Erucic Acid

Brassica junceais a crucial cultivated mustard species and principal oilseed crop of India and Madhya Pradesh, grown for diverse vegetables, condiments, and oilseeds. Somaclonal variation was explored as a probable source of additional variability for the manipulation of fatty acids, especially low erucic acid contents that may be valuable for this commercially important plant species. The plantlets regenerated from tissue cultures (R0), their R1 generation and respective parental lines were compared for morpho-physiological traits and fatty acid profile for the probable existence of somaclonal variations. The first putative somaclone derived from genotype CS54 contained 5.48% and 5.52% erucic acid in R0 and R1 regenerants, respectively, compared to the mother plant (41.36%). In comparison, the second somaclone acquired from PM30 exhibited a complete absence of erucic acid corresponding to its mother plant (1.07%). These putative somaclones present a source of variation for exploitation in the development of future mustard crops with low erucic acid content.
