Investigation of the effect of vegetable Brassica oleracea alleles on the productivity of B. napus canola

持续改良油菜以获得更高的产量、更好的农艺和种子质量性状以及对包括根肿病在内的不同疾病的抗性，将保持这种作物在农场层面的盈利能力。为此，需要携带有利基因（等位基因）的广泛遗传基础种质，这对于改良杂交油菜品种的开发尤其重要。与其A亚基因组相比，卡诺拉中的等位基因多样性，特别是在其C亚基因组中的等位基因多样性是狭窄的;因此，该基因组中有利等位基因的渐渗将确保通过育种改进该作物。在NSERC支持的先前研究项目中，阿尔伯塔（UofA）油菜计划已经开发了数百种遗传多样的油菜品系，携带不同蔬菜B的等位基因。甘蓝（C基因组），如羽衣甘蓝、卷心菜、花椰菜和花椰菜，以拓宽加拿大卡诺拉的C亚基因组的遗传基础。这一油菜种质在世界上是非常独特的;在育种中使用这一种质将拓宽该作物C亚基因组的遗传基础，从而使加拿大的整个油菜产业受益。为此，了解了B的作用.当在基于知识的育种计划中使用这些外来等位基因时，将需要油菜中的甘蓝等位基因。拟议的研究将调查B的影响。甘蓝等位基因对种子产量、农艺性状和种子品质性状以及杂种优势的影响，以用于杂交油菜育种，这将在根肿病抗性性状的背景下完成，以用于从本研究开发的油菜品系在商业杂交油菜品种开发中的可能用途。

Continued improvement of canola for higher yield, better agronomic and seed quality traits, and resistance to different diseases including clubroot will maintain the profitability of this crop at the farm level. For this, broad genetic base germplasm carrying favorable genes (alleles) is needed, and this is especially important for the development of improved hybrid canola cultivars. Allelic diversity in canola, especially in its C sub-genome is narrow as compared to its A sub-genome; therefore, introgression of favorable alleles in this genome will secure the improvement of this crop through breeding. In a previous research project supported by NSERC, the University of Alberta (UofA) Canola Program has developed several hundred genetically diverse canola lines carrying alleles of different vegetables B. oleracea (C genome), such as kale, cabbage, cauliflower, and broccoli, to broaden the genetic base of the C sub-genome of the Canadian canola. This canola germplasm is very unique in the world; the use of this germplasm in breeding will broaden the genetic base of the C sub-genome of this crop, thus benefiting the whole canola industry in Canada. For this, an understanding of the effect of the B. oleracea alleles in canola will be needed while using these exotic alleles in a knowledge-based breeding program. The proposed research will investigate the impact of the B. oleracea alleles on seed yield and agronomic and seed quality traits as well as on heterosis for use of the knowledge in the breeding of hybrid canola, and this will be accomplished in the background of clubroot resistance trait for the possible use of the canola lines developed from this study in the development of commercial hybrid canola cultivars.
