Study and Selection of Chewing Cane Variety CZ26 for High Quality, High Yield and Multi-resistance
摘要
Abstract
The result of Provincial Region Tests and Productive Trials in 12 points （times） indicated that the mean emergence rate （average, the same below） of CZ 26 was 41.91% and 2.27% higher than that of the check variety HN 54-11. The mean tillering rate was 66.13% and 4.46% higher. The mean plant height was 256 cm and 20 cm higher. The mean diameter was 3.17 cm and 0.20 cm larger. The millable stalks were 61545 stalks/hm^2 and 7605 stalks/hmz more. The mean stalk weight was 2.0181 kg/stalk and 0.3783 kg/stalk heavier. The mean yield was 125400 kg/hm^2 and 35970 kg/hm： and 40.22% higher. The mean extraction ratio of juice was 79.29% and 1.04% higher. The mean sucrose content in juice was 13.15% and 0.53% higher. The cane juice was liked very much by consumers for its tasty and sweetness. The mean fiber percentage was 6.90% and 0.18% lower, therefore the stalk was very soft and crisp. The reducing sugar was corresponding with the check variety. The color of stalk is purplish red, and as a result, the exterior appearance was pleasing, increasing its competitiveness in market. The mean Brix in field was 16.87° Bx and 0.58 °Bx higher （absolute value）. The mean sucrose in cane was 12.20% and 0.27% higher （absolute value）. The mean sugar yield was 14910 kg/hm^2 and 4875 kg/hm^2 more and 48.58% higher. The lodging-resistance was very strong; the drought-resistance was stronger. CZ 26 has the highest resistance to smut, and resistance to brown stripe and mosaic but it was infected lightly with top rop. The resistance to borer was stronger but the cold resistance and perennial characteristics were poorer. So CZ 26 was a improved chewing cane variety with high quality, high yield, multi-resistance. Its quality was similar to Badila, a chewing cane variety with good agronomic, yielding, commercial and technological characters.关键词
