Analysis and Evaluation of Introduced Rape New Variety “Qingza No.7” in Xiangyang
摘要
Abstract
A new early -mature spring rape variety "Qingza No. 7" was introduced into Xiangyang area of Hubei province. Taking the local mainly -cultivated rape variety "Huayouza No. 9" as the control, the characteristics of "Qingza No. 7" were studied at two different nitrogen application levels. Results indicated that the whole growth and developmental duration of "Qingza No. 7" was shorter than that of " Huayouza No. 9", and the each growth stage of the former was obviously earlier than that of the latter. At two different levels of nitrogen application, "Qingza No. 7" had lower rapeseed yield, lower number of siliques per unit area and number of seeds per silique, and higher kilo - kernel weight than the control variety "Huayouza No. 9". Although the rapeseed yield of the introduced "Qingza No. 7" was lower than that of the local mainly -cultivated variety, "Qingza No. 7" had earlier bolting stage and better tender - stem quality than the control, so this variety could be planted as the special rape variety for the harvest of tender - stem in Xiangyang area.关键词
