Regional Test for Sugarcane Varieties with Highly Yield and Sugar Content and Resistance to Adversity

During 2011~2012, regional test was conducted on several varieties and Guitant 11, the check variety,to compare their main agronomic characters and technical characters. Compared with the check variety, the germination rate of Neijiang97-113 and Mingyin1991 was increased by 4.7% and 7.4%(absolute value)respectively. The tillering rate was increased by 1.3% and 12.9%(absolute value). The plant height was increased by 40.7 and 24.6 cm. The stalk diameter was increased by 0.21 and 0.26 cm. The millable cane was increased by 6989 and 17480 stalks/hm2. The stalk weight was increased by 0.37 and 0.33 kg/stalk. The cane yield was increased by 42.19 and 50.50 t/hm2(by rates of 46.59% and 54.94%). The brix was increased by 1.8and 0.3 ?Bx. The sugar content of both was increased by 1.9%. The results indicated that Neijiang97-113 and Minyin1991 are excellent in agronomic characters such as adaptability, resistance to adversity, ratooning ability,stability, yield and sugar contents.
