چکیده
Abstract The aims of this study were to estimate the diversity doubled haploid population winter oilseed rape ( Brassica napus L.) in terms yield, yield structure and seed colour, determine correlation between studied traits their heritability, select best yellow-seeded genotypes. We 44 haploids, obtained from F 1 hybrids a cross black-seeded DH H 2 -26 line Z-114 line, as well parental forms. greatest variation populations was observed for number pods per plant, while smallest variability thousand weight. Seed positively correlated with plant seeds pod, but negatively yellow colour. broad-sense heritability coefficient highest colour lowest plant. When divided into 4 homogeneous groups according genotypes differed significantly respect all traits. A group lines black characterized by yielding group, that yellow–brown seeds, had on average pod selected. Four gave higher yields than line.

Effect of sowing date on yield and yield components of three oilseed rape varieties
In order to elucidate the effect of sowing date on oilseed rape (Brassica napus L.) yield and yield components, three varieties including Tower, Rafal and Global were sown from November 7 to December 22, 1998-99 in four dates with 15day intervals in Dezful region. A split-plot design based on randomized complete blocks with four replications was used in which levels of sowing dates and cultivar...
