摘要：

为了评估感病区和非感病区对甜菜根产量和含糖率的影响,本试验对2017年和2018年的1个感病区和6个非感病区的10个甜菜品种的根产量和含糖率进行了测定。试验设计采用随机完全区组设计,配对t检验、多元方差分析对2017年和2018年种植于感病区和非感病区的10个甜菜品种的根产量和含糖率数据进行分析,共设置4个重复。多元方差分析结果显示,除2018年3区外,与2017年相比,2018年其他6个区域的4个重复的根产量差异不显著;2017年和2018年7个区域的10个品种之间显示出显著和非显著差异。箱线图显示,2017年的含糖率和2018年根产量与含糖率在7个区域的感病区（1区）与非感病区（2区~7区）均存在显著差异（配对t检验,p<0.001,p<0.001,p<0.001）。2017年,1区中的BETA377、BETA468、ST13112、LN90905、KWS2314、SV1554、BETA379和KWS9147没有显著差异,并处于较高水平。2018年,1区Knhn1357的根产量与其他9个品种具有显著差异,且处于高水平。在区域1中,2017年HI0554、BETA377、Kuhn1357、SV1554的含糖率与2018年HI0554、BETA468、KWS2314、Kuhn1357含糖率无显著差异,且处于较高水平。2017年和2018年,除2017年的LN90905与HI0554的根产量有显著差异外,5区10个品种的根产量和含糖率差异不显著。2017年和2018年,区域1的根产量和含糖率均存在显著差异（配对t检验,p<0.001,p=0.036）。区域5中,2017年和2018年10个甜菜品种的根产量差异不显著,含糖率差异显著（配对t检验,p=0.931,p<0.001）。经综合评估,ST13112,LN90905和SV1554抗病力较低;Knhn1357、BETA377、BETA468、KWS2314、KWS9147、BETA379和HI0554的抗病力较强。在同一区域和品种之间的根产量和含糖率存在显著性差异。

Abstract:

To evaluate the impact of susceptible and non-susceptible areas on root yield and sugar content of sugar beet, the root yield and sugar content of 10 sugar beet varieties were measured in 2017 and 2018 in 1 susceptible area and 6 non-susceptible areas. The experiment was a randomized complete block design, and the paired t-test and multivariate analysis of variance were adopted to analyze tuber yield and sugar content of the ten sugar beet varieties with 4 replicates. The results of multivariate analysis of variance showed that, except zone 3 in 2018, there was no significant difference in root yield among the 4 replicates in the other 6 zones in 2018 compared with 2017. Significant and non-significant differences were shown among the 10 varieties in the 7 areas in 2017 and 2018. The boxplot showed that the sugar content in 2017 and the root yield and sugar content in 2018 were significantly different between the susceptible area (zone 1) and the non-infectious areas (zone 2 to 7) (paired t-test, p<0.001, p<0.001, p<0.001). In 2017, BETA377, BETA468, ST13112, LN90905, KWS2314, SV1554, BETA379 and KWS9147 in zone 1 had no significant differences and were at a high level. In 2018, the root yield of Knhn1357 in zone 1 was significantly different from that of the other nine varieties and was at a high level. In zone 1, the sucrose content of HI0554, BETA377, Kuhn1357 and SV1554 in 2017 and HI0554, BETA468, KWS2314 and Kuhn1357 were not significantly different from each other in 2018 and were at a higher level. In 2017 and 2018, except that LN90905 and HI0554 in 2017 had significant differences, there was no significant difference in root yield and sugar content of the 10 varieties in zone 5. In 2017 and 2018, there were significant differences in root yield and sugar content in zone 1 (paired t-test, P<0.001, P =0.036). In zone 5, there was no significant difference in root yield and significant difference in sugar content among the 10 varieties in 2017 and 2018 (paired t-test, p=0.931, p<0.001). After a comprehensive assessment, ST13112, LN90905 and SV1554 are less resistant to the disease, Knhn1357, BETA377, BETA468, KWS2314, KWS9147, BETA379 and HI0554 have strong disease resistance, and there are significant differences in root yield and sugar content within the same zone and among the varieties.
