引进果蔗新品种(系)区域试验研究

Performance of Yield and Cane Sugar Content of Introduced Fruit Sugarcane Varieties(lines) in Guizhou Regional Test

对4个果蔗新品种（系）贵引07-15、贵引07-16、黔蔗07-126和贵引07-04在贞丰、兴义、望谟进行了区域试验研究。结果表明：4个新品种（系）在海拔800m以下不同类型土壤上种植均比较适宜，其综合农艺性状表现较好，尤其是贵引07．15、贵引07—16和黔蔗00—126表现突出，蔗茎产量较黔糖3号增产28％-35％，较罗汉蔗增产140％-152％；蔗糖分含量较黔糖3号增加0．7～1．11百分点，较罗汉蔗增加0．9—1．31百分点，且增产增糖均达极显著水平，具有进一步研究和生产示范价值。

Four introduced fruit sugarcane varieties （ lines）, Guiyin 07-15, Guiyin 07-16, Qianzbe 00-126 and Guiyin 07-04, were tested in regional tests of Zhenfeng, Xingyi and Wangmo sites. The results showed that the comprehensive agronomic character performance of four tested varieties （lines） was good and the tested varieties （lines） could be planted in different kinds of soils below an elevation of 800 meters. The stem yield of Guiyin 07-15, Guiyin 07-16 and Qianzhe 00-126 was 28 % -35 % and 140 % - 152 % higher than Qiantang 3 and Luohanzhe, and the cane sugar content of Guiyin 07-15, Guiyin 07-16 and Qianzbe 00-126 was 0.7 % - 1.11% and 0.9 % - 1.31% higher than Qiantang 3 and Luohanzhe respectively. Therefore, the tested varieties （lines） should have values of further production, demon- stration.
