Studies on techniques of sugarbeet Rhizomania integrated controlⅠ.Comparison experiments of variety regional testing

采用多项栽培措施等合理配套综合防治技术 ,对引进品种进行2年的区域比较试验 ,结果表明 :引进品种表现出较强的抗病性 ,1997年平均公顷产量近60t,含糖率平均为15.5%;1998年平均公顷产量高达75t以上 ,含糖率在12 %左右。筛选出综合性状表现优良的2个引进品种Beta4006和Beta4035。

The comparison experiments with the full use of resistant varieties combined rationally with cultural practices and other field management measures, results of the testing varieties shown that have stronger resistance to sugarbeet rhizomania and the stability in characters. In the trial of 1997,average root yield was more than 60 tons/ha and average sugar content reached 15.5%, in 1998, average root yield was more than 75 tons/ha, but average sugar content decreased to 12% because of high temperature in Septe. and early havest. Two varieties Beta4006 and Beta4035,shown that were very promising in integrated characters .
