国家第15轮甘蔗品种区试德宏点评价

Evaluation of the 15th Nationnal Sugarcane Varieties Regional Trial in Dehong

2021~2024年,在德宏综合试验站开展了国家第15轮甘蔗品种区试1新2宿试验,以桂柳05136为CK1、以粤糖93159为CK2,对14个参试品系的农艺性状、工艺性状、抗病性等进行调查、测定,并通过产量、糖分、含糖量、抗病性等指标对各个参试品种(系)进行综合评价。试验结果表明:不同的品种(系)在植株生长表现、蔗茎产量、糖分、含糖量等方面表现出明显的差异。其中,桂南亚146210蔗茎产量为107.88 t/hm^(2),比CK1增产0.76%,比CK2增产27.07%,11月至翌年3月平均糖分为15.88%,比CK1、CK2分别高0.35、0.16个百分点,含糖量为17.27 t/hm^(2),比CK1、CK2分别高3.97%、28.50%,综合表现最好;桂糖13334蔗茎产量为128.77 t/hm^(2),比CK1增产20.26%,比CK2增产51.67%,11月至翌年3月平均糖分为14.70%,比CK1、CK2分别低0.83、1.02个百分点,含糖量为19.05 t/hm^(2),比CK1、CK2分别高14.69%、41.74%,综合表现较好;其余品种(系)表现不够理想,不建议在本试验区域推广种植。

In 2021~2024,the 15th National Sugarcane Varieties Regional Trial of one-year new planting and two-year ratoon test was carried out at Dehong Comprehensive Experimental Station,with Guiliu05136 as CK1 and Yuetang93159 as CK2.The agronomic traits,technological traits,disease resistance of 14 cultivars were investigated or measured,and the varieties tested were evaluated synthetically through the yield,sucrose,sugar content and disease resistance.The results showed that different varieties had significant differences in plant growth performance,sugarcane yield,sucrose and sugar content.In addition,the yield of Guinanya146210 was 107.88 t/hm^(2),an increase of 0.76%than CK1,and an increase of 27.07%than CK2,the average sugar was 15.88%,an increase of 0.35 and 0.16 percentage points than CK1 and CK2;sugar content was 17.27 t/hm^(2),which was 3.97%and 28.50%higher than CK1 and CK2,with the best comprehensive performance.The yield of Guitang13334 was 128.77 t/hm^(2),an increase of 20.26%than CK1,and an increase of 51.67%than CK2,the average sugar was 14.70%,a decrease of 0.83 and 1.02 percentage points than CK1 and CK2;sugar content was 19.05 t/hm^(2),which was 14.69%and 41.74%higher than CK1 and CK2,with the better comprehensive performance.The other varieties were not ideal enough to be popularized in this experimental area.
