芝麻在襄阳地区是主要的油料作物,约占全区油料面积85％以上。近年来种植面积在60万亩左右。但单产很低,常年亩产80—90斤。旱涝灾害年份亩产仅40—50斤。这不仅是由于栽培技术水平不高,而且也是由于缺少适合襄阳地区自然条件和栽培制度的品种。因此,尽快为芝麻生产提供产量高、抗性强、品质好的品种是一项重要的育种任务。 从1973年开始,襄阳地区农科所就着手进行芝麻新品种的选育。目前,已选育出芝麻新品种“襄芝2号”。该品种表现早熟、高产、适宜我区种植。近年来,不仅在襄阳地区已大
Sesame oil in Xiangyang region is the main crop, accounting for more than 85% of the region’s oil area. In recent years, the planting area is about 600,000 mu. However, yields are very low, perennial 80-90 kg per mu. Droughts and floods annual mu yield of only 40-50 pounds. This is not only due to the low level of cultivation techniques, but also due to the lack of species suitable for natural conditions and cultivation systems in Xiangyang. Therefore, as soon as possible for sesame production to provide high yield, strong resistance, good quality varieties is an important breeding task. Since 1973, Xiangyang Agricultural Science Institute has embarked on the breeding of new sesame varieties. At present, a new sesame variety “Xiangzhi 2” has been bred. The varieties of early performance, high yield, suitable for planting in our district. In recent years, not only in Xiangyang area has been large
