国外引进甘蔗品种比较试验

A Comparison Test of Foreign Sugarcane Cultivars

对引进的18个国外甘蔗品种进行试验,结果表明:8个国外甘蔗品种表现为出苗率较好,分蘖力强,植株高大;Vmc96-60、CP94-1100蔗茎产量高、蔗糖分好,可以考虑进一步进行区域性试验,繁殖和示范推广;Q202、Vmc81-202、Vmc95-09、Q203蔗茎产量高、但蔗糖分较差,总含糖量和对照无明显差异;其余品种在各个方面表现一般,这些品种可以考虑进一步观察试验,以评价其利用价值。

Eighteen foreign sugarcane cultivars were tested, in which eight cultivars showed good performance in sprouting, tillering and stalk length. Vmc96-60 and CP94-1100 were selected as elites for their high yield and sucrose content, which were considered with potential to be involved in regional test, further propagation, and even demonstration and popularization. Q202, Vmc81-202, Vmc95-09 and Q203 were high in stalk yield, but relatively poor in sucrose content, and there was no significant difference in total sugar yield compared with the control. The other genotypes were ordinary in this research, and advised to be further observed to develop their potential in application.
