摘要
为培育稳产、高产、高含油量、低芥酸和低硫甙含量的油菜新品种,缓解人类食品和动物饲料中优质油菜产品供不应求的状况。文章详细阐述了高产、高油、双低油菜品种浙油50的选育过程,并就其产量、品质、抗性等性状表现进行综合分析,还探讨了浙油50的育种策略。以9715为母本,鉴6为父本配制杂交组合,历经8代农艺性状、品质性状和产量的选择,育成了高产、高油的优质油菜新品种浙油50。区试和生产试验结果表明,浙油50最高含油量达50.78%,产量达303.8 kg·667 m-2。该品种现已在长江中下游地区有较大面积的推广应用。
In order to fill the developing gap in the supply and demand for high quality oilseed crops for human food and animal feed,it is necessary to develop varieties with high and stable seed and oil yield,as well as low content of glucosinalate and erucic acid. The objective of this paper was to introduce the breeding process of a new rapeseed cultivar,Zheyou 50,and its yield,quality,and disease and abiotic stress resistance. Furthermore,the strategy for breeding of Zheyou 50 was also discussed,which will serve as useful tool for establishing suitable breeding program for rapeseed improvement. Zheyou 50,with high seed and oil yield was successfully bred using 9715 and Jian 6 as female and male parents,after 8 generations selection based on agronomic,quality,and yield traits. It exhibited the highest seed oil content and maximum yield at 50. 78% and 303. 8 kg·667 m- 2in the regional and production test,respectively,and it is one of the most suitable and high oil content rapeseed varieties in the middle and down reaches of Yangtz River.
