Abstract: To breed rapeseed varieties with early maturity and yield stability for the mountain area in Yunnan Province, and to promote the sustainable development of agricultural production, the domestic excellent varieties were introduced and crossed with the local elite varieties with good quality, high yielding and high level resistance. Two new rapeseed varieties of‘Yuhongyou 3’and‘Yuhongyou 4’with early maturity, high oil content and yield stability were developed and released at provincial level in Yunnan using multiple generation selection and quality analysis. In this study, the breeding process of the new rapeseed varieties of ‘Yuhongyou 3’and‘Yuhongyou 4’was elaborated. Furthermore, the suitable cultivation techniques of these two varieties were provided. The breeding process and cultivation techniques are important for the rapeseed breeding in Yunnan, and the application of these two new rapeseed varieties plays a significant role in promoting the development of rapeseed industry in Yunnan Province.
