Abstract: 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-2 in 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.
