چکیده مقاله:
The present study was carried out to estimate genetic variability parameters for some traits such as pods per plant, cell membrane stability, one thousand kernel weight, flowering period, grain filling period, chlorophyll content, relative water content, leaf excised water content, seed per pod and pod length, in ۱۶ winter rapeseed genotypes. Statistical analysis showed significant differences between the tested genotypes. Genotypic and phenotypic coefficients of variations were high for yield, pods per plant and cell membrane stability. Heritability estimates were high for pods per plant, cell membrane stability, one thousand kernel weight and flowering period. A high genetic gain was observed for pods per plant and cell membrane stability. Correlation analysis showed a significant and negative relationship between the flowering and grain filling period (-۰.۸۸۳) and between cell membrane stability and chlorophyll content (SPAD) (-۰.۵۸۷). A positive and significant correlation was found between the grain yield and relative water content (۰.۶۰۳).
