全国第5轮甘蔗新品种区域试验湛江区试点结果分析

Results of the Fifth Round National Regional Trial for Sugarcane New Varieties in Zhanjiang Region

2005～20062年新植和2年宿根的结果表明,14个参试品种中,粤糖94-128增产增糖显著,农艺性状及宿根性能好,居于首位;Mex105、福农98-1103、CP8号和闽糖96-1409增糖幅度明显,增产不明显,农艺性状较好,宿根性能方面,Mex105、CP8号和闽糖96-1409强,福农98-1103较差;桂糖94-116和Q170增产幅度大,但增糖不明显,云蔗99-596产量、糖分均介于2对照种之间;其余品种比2对照种均有不同程度的减产、减糖,表现较差。

Results from the trials on two crops of plant cane and one crop of ratoon cane during 2005 and 2006 showed that both cane and sugar yields of YT94-128 was significantly higher than those of ROC10（CK1） and ROC 16（CK2）, ranking first among the fourteen varieties tested. It performed strong ratooning ability with good agronomic characteristics. Mex 105, FN98-1103, CP8 and MT96-1409 were obviously higher in sugar yield than the two checks, but not in cane yield; the ratooning ability of Mex105, CP8 and MT96-1409 was good, but FN98- 1103 poor, all of them presented good agronomic characteristics. GT94-116 and Q 170 produced higher cane yield than the two checks, but only given even sugar yield when compared with the checks. YZ99-596 was between the 2 check varieties in both cane and sugar yields. The other tested varieties were poorer than the two checks in yield, sucrose content, ratooning ability, etc.
