To better understand the future variation trend and group difference on farmers’ subjective demand of rapeseed variety characters, and to provide suggestions for cultivation of rapeseed cultivars, survey data of 17701 samples from 18 provinces with fixed observation points of China agriculture research system (rapeseed) from 2009 to 2020 was collected. Descriptive statistical method was used to report the variation trend of farmer’s subjective demand of rapeseed nine variety characters over the past years. Group difference was analyzed between different regions, topographic regions, land scale, age and education level. The results showed that: 1. There were significant differences in farmers’ subjective demand for different rapeseed variety characters, according to the annual average of whole nation, in order from large to small is: yield(86.15%), disease resistance(68.02%), oil extraction rate(62.28%), lodging resistance(61.43%), germination rate(43.47%), insect resistance(41.41%), suitable for mechanization(35.63%), double-low(35.60%), price of seed(30.98%). 2. From 2009 to 2020, farmers' subjective demand for yield decreased by 6.68 percentage points, oil extraction rate increased by 28.30 percentage points, insect resistance decreased by 17.30 percentage points, disease resistance decreased by 1.98 percentage points, lodging resistance increased by 15.61 percentage points, price of seed decreased by 17.60 percentage points. From 2015 to 2020, farmers' subjective demand for germination rate increased by 33.13 percentage points, double-low increased by 9.29 percentage points, suitable for mechanization increased by 2.71 percentage points. 3. There were significant differences in the subjective demands of rapeseed variety characters among different farmer groups. It was suggested that in the future, high-yielding and high oil extraction rate rape cultivars should be better cultivated, the cultivate of rapeseed cultivars with more resistance should continue strengthened, rapeseed cultivate and promote with double-low, high germination rate and suitable for mechanization character should be more targeted. In order to increase the benefits of rapeseed cultivars workers, a number of high quality and high price rape varieties can be launched.
