Abstract: The comparative test of ten vegetable rape varieties was conducted to study their growth season, yield of the tender flower stalk and fresh feed, characteristic and taste of the tender flower stalk, and final economic benefit. The results showed that there were four early-maturing varieties, five medium maturing varieties and one late maturing variety according to the number of days from planting to bolting. The tender flower stalk yield of early-maturing varieties was higher than medium maturing and late maturing varieties in the all, the fresh feed yield of all varieties was 5.9%~36.1% lower than that of Huayouza 62, and the total biological yield was 0.7%~20.8% lower than that of Huayouza 62. The per plant weight and stem diameter of four early-maturing varieties were lower than those of medium and late maturing varieties. In this study, the stalk-leaf ratio demarcation point of oil and vegetable dual-purpose varieties and specific vegetable varieties was 0.33. The taste of the tender flower stalk was delicious and well received by the masses. The ten vegetable rape varieties had high output value. The common vegetable rape varieties reached more than 58 180 yuan/hm², while the selenium enrichment vegetable rape varieties reached more than 195 067 yuan/hm² in economic benefit.
