果蔗新品系黔蔗06/126的农艺性状及产量表现

Agronomic Traits and Yield Performance of the New Sugarcane Strain Qianzhe 06/126

黔蔗06/126是贵州省亚热带作物研究所选育的果蔗新品系,为了鉴定该品系的农艺性状和产量表现,于2010-2011年以黔蔗06/126和黔糖3号(CK)为材料进行了品种比较试验。结果表明:黔蔗06/126新植蔗的出苗率、宿根发株率和单茎重分别较CK增加12.9%、16.6%和19.7%,综合农艺性状表现优良,新植蔗产量158.75 t/hm2,宿根蔗130.83 t/hm2,平均144.80t/hm2,分别比CK增产21.5%、19.1%和20.4%;2年3点生产示范中,新植蔗和宿根蔗的平均产量为117.23 t/hm2,较CK增产18.8%,且该品系的抗病虫能力较CK强,抗旱能力相当。

For the sake of identifying the agronomic traits and field performance of Qianzhe 06/126 which is a new sugarcane strain bred by Guizhou Institute of Subtropical Crops, a variety comparison test was conducted during 2010-2011 taking Qianzhe 06/126 and Qiantang 3 （CK） as the materials. The results showed that the emergence rate, ratoon seedling emergence rate and single stalk weight were higher than CK by 12.9 %, 16.6 % and 19.7 % respectively. And the comprehensive agronomic traits were excellent. The yields of new sugarcane and stubble cane were 158.75 and 130.83 t/hm^2 with an average of 144.80 t/hm^2, higher than CK by 21.5 %, 19.1% and 20.4 % sep-arately; In the production demonstration test in three spots during 2010-2011, the average yield was 117.23 t/hm^2, 18.8 % higher than CK. Moreover, the pest and disease resistance ability of Qianzhe 06/126 was stronger than CK, and the drought resistance ability was similar to CK.
