4个果蔗新品种(系)高产、稳产及适应性分析

对4个果蔗新品种黔蔗00-126、贵引07-15、贵引07-16和贵引07-04的区域试验和生产示范结果进行了高产稳产及适应性分析,以期为生产上大面积的应用推广提供技术支撑。结果表明,区试中4个品种(系)的新植蔗平均产量比对照分别增产24.74%~48.15%、宿根蔗比对照增产14.84%~34.32%,增产效果均达显著或极显著水平。4个品种(系)的标准差(49.21~92.04kg)和变异系数(0.56%~1.11%)2项指标值都较低,高稳系数(96%(HSCi(134%)较高。综合说明4个品种(系)的丰产性好、稳产性高,而且适应性较强,可以在海拔800m以下各蔗区大面积应用推广。

Analysis on High Yield, Stability Yield and Adaptability of Four New Fruit Sugarcane Varieties (Lines)

The high yield, stable yield and adaptability of four new fruit sugarcane varieties (00-126, Guiyin07-15, Guiyin07-16 and Guiyin07-04) were analyzed from their regional tests and production demonstration to provide the technological support for their application popularization on a large scale. The results showed that the average yields of planting cane and biennial root cane of four sugarcane varieties(lines) were 24.74 %-48.15 % and14.84 %-34.32 % higher than CK respectively and there was very significant difference or significant difference in yield between CK and four tested varieties(lines). The standard deviation (49.21-92.04 kg) and variance coefficient(0.56 %-1.11 %)of four tested varieties(lines) were lower and the coefficient of high-stable yield (96 %﹤HSC_i﹤34 %)was high, which expresses that four new sugarcane varieties(lines) with good high-stable yield and strong adaptability can be popularized in areas below an elevation of 800 meters on a large scale.
