Genetic Variability and association of some quantitative characters and protein fingerprinting in some canola genotypes
R. M. Fahmyand S.F. M. El-Hefnawy
The aim of this study was to estimate the genetic parameters and genetic advance from the selection of yield and its components, which can provide basic information for the explanation of valuable lines and check variety combinations of canola and protein fingerprinting. Fifteen lines and check variety were planted in 2015/ 2016 and 2016 / 2017, at Bahteem Agricultural, Research Station. The selection was practiced in the first season on the basis of 50% flowering, physiological maturity, seed yield/plant and seed oil content. A total of 150 selected plants were evaluated in a replicated trial in 2016/ 2017 season at Bahteem Res. Station. Genetic variability, heritability, Phenotypic and genotypic coefficient of variation, and genetic advance from selection were estimated. Significant differences were observed among check variety serw-4 selected plants in both seasons for most studied traits. Broad sense heritability estimates in the second season ranged from 1.00 to 81.00%. High heritability coupled with high genetic advance from selection was recorded for seed yield/plot, seed yield/plant, first silique height, and physiological maturity. Hence selection for these traits is expected to be effective. There was a positive and highly significant genotypic correlation coefficient between seed yield/plot and seed oil percentage, indicating the possibility of increasing oil content with high seed yield/plot.
The electrophoresis profile of seed storage protein for fifteen lines and check variety. The Molecular weight 188 polypeptide bands of diver’s molecular weight ranging from 12 to 155 KD. Based on molecular weight the banding pattern revealed specific regions (12 to 35 KD) comprised 8 bands.
