我区种植甜菜的条件在全国来说是最好的,不但单产高根含糖率也较高,而且病害少,并已有二十来年的种植历史。但由于良种繁育工作跟不上,品种混杂退化较为严重,根中含糖率逐年下降,白粉病为害严重,迫切需要选育出丰产、高糖、抗病强的新品种来更换。根据国内外先进科研经验,结合我区具体情况,我们先后开展了甜菜系选、杂交、
The conditions for growing beet in our district are the best in the country. Not only the high root yield per plant but also the higher sugar content with less disease and more than 20 years of planting history. However, due to poor seed breeding work, the variety degradation is more serious. The sugar content in the root declines year by year, and the powdery mildew is seriously damaged. Therefore, it is urgent to breed new varieties with high yield, high sugar and disease resistance. According to advanced research experience at home and abroad, combined with the specific circumstances of our region, we have carried out the beet line selection, hybridization,
