| 摘 要： | 采用广义联合方差分析和回归分析，对福建省１９９５－１９９６年甘蔗新品种区试试验资料的８个供试品种的丰产性和稳定性进行估测和评价。结果表明：闽糖８８－１０３蔗茎产量比对照种增产３１．５％，经Ｌ．Ｓ．Ｒ测验，增产达极显著水平，其回归系数接近１，是一个高产稳产、早中熟、适应性广、农艺性状优良的新品种；选５０蔗茎产量比对照种增产２２．６％，增产达显著水平，回归系数ｂ＜１，是一个高产稳产、中晚熟、适应性广的甘蔗新品种；闽糖９０－５２５、闽糖９０－９１３和闽糖８５－８４３个品种蔗茎产量分别比对照种增产１２．８％、１０．８％、８．７％。除闽糖９０－９１３的回归系数ｂ＝１．２９０１外，闽糖９０－５２５、闽糖８５－８４回归系数ｂ＜１，均属早熟高糖、丰产稳产、适应性广的甘蔗良种；闽糖８７－９１２蔗茎产量比对照种增产１５．１％，增产未达显著水平，其回归系数ｂ＜１，属丰产稳产、中晚熟品种。

Deterimination, Comparison and Analysis of the Abundant Productivity and Stability of New Sugarcane Varieties |

| Abstract: | By means of the general combining variance and regression analysis, the abundant productivity and stability of 8 new sugarcane varieties in the regional test during 1995-1996 were determined and evaluated in Fujian Province. The results showed as follows. The cane yield of Mintang 88-103 was 31.5% higher than the check, Mintang 70-611, and according to L.S.R. test, the yield increase reached extremely significant level, while the regression coefficient was close to 1. This new early-middle season variety had a high and stable yield, wide adaptability and excellent agronomic characters. The cane yield of Xuan 50 was 22.6% higher than the check, and the yield increase reached significant level while the regression coefficient b<1. This new middle-late season variety had a high and stable yield and wide adaptability. The cane yields of three varieties,Mintang 90-525, Mintang 90-913 and Mintang 85-84 were 12.8%, 10.8% and 8.7% higher than the check, respectively. The regression coefficient of Mintang 90-913 was b=1.2901 but those of Mintang 90-525 and Mintang 85-84 were b<1, which indicated that the excellent sugarcane varieties had early maturity, high sucrose contents, abundant and stable productivity and wide adaptability. THe cane yield of Mintang 87-912 was 15.1% higher than the check, and the yield increase was below the significant level while the regression coefficient b<1. It was a middle-late season variety with abundant and stable productivity. |
