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. ...

Oilseed rape (Brassica napus) or Canola is an important oilseed crop produced and consumed globally. The predicted increase in the frequency of high-temperature events associated with climate change poses a threat to productivity. In present work, we report impact short-term heat stress on reproductive fitness yield components Canola. Short episodes, especially above 36°C, resulted diminished d...

Crucifer-feeding flea beetles, Phyllotreta spp., are chronic insect pests in Canadian prairie canola production. Multiple laboratory and field feeding bioassays were conducted to determine the susceptibility of a wide range of crucifer species, cultivars, and accessions to feeding by flea beetles with the goal of discovering sources of resistant germplasm. In 62 bioassays of 218 entries, no con...

Evaluation of relationships is of prime importance in any breeding studies. In current research, genetic diversity among different rapeseed genotypes from several geographical origins including Canada, Australia, Germany, France, Denmark, Netherlands, Sweden, Iran, and Somegenotypesof unknown origin, were evaluated by RAPD and ISSR markers. All of the generated bands using 12 RAPDs and 15 ISSRs...

Phytohormones play pivotal roles in the response of plants to various biotic and abiotic stresses. Boron (B) is an essential microelement for plants, and Brassica napus (B. napus) is hypersensitive to B deficiency. However, how auxin responds to B deficiency remained a dilemma for many years and little is known about how other phytohormones respond to B deficiency. The identification of B-effic...

This study was conducted on two canola (Brassica napus) cultivars, Okapi a winter type and cold tolerant and Rgs003 a spring type and cold sensitive. Seedlings were grown in an environmentally controlled growth room with 16 h d-1 photoperiod at 22/16 °C (day/night, control). At the 4-leaf stage, half of pots were transferred to a cold growth room for 7 d at 10/3°C (day/night, cold treatment) an...
