15 varieties of Yunnan Province, the eighth set of sugarcane varieties regional trial ( material) in newly planted eight point two years , year ratoon data collected . Hectares of sugar content , analytical basis . (1) points of the tested varieties yield analysis showed that : the varieties of 1 , 5 , 12, etc. A ground the new plant should be eligible for high-yielding varieties 4 , 2 , 13 B perennial planting should be eligible for multiple comparisons using analysis of variance and SSR tests high yield. Other results see text ; ( 2) analysis of variance and LSR the tests analysis varieties in multi-point and different planting the control species of high-yield : Pilot A, all varieties of a significant increase compared with the control . The vegetation period , except varieties 7 and 8 , the average yield of all varieties compared with the control significantly increase production . Other results see text ; ( 3) with a regression coefficient and regression plot analysis the newly planted , ratoon and Shinjuku average of the high and stable yield of show : varieties of 3 , 2 , 6 high and stable yield varieties 10, 1 , 9 , and other high-yielding but not stable varieties 7 low-yielding stable , while the variety of low-yielding stable without ; ( 4 ) with high stability coefficient (HSC) analysis of newly planted perennial root and Shinjuku varieties , high yield stability of the : Shinjuku average high and stable yield from high to The low qualifying for varieties of 12 , 9 , 10 , 1 , 3 , 11 , 13 , 5 , 2 , 6 , 4 , 8 , 7 ??. The correlation analysis of the variation of parameters and significance test between the average yield and high stability coefficient was highly significant correlation, the correlation coefficient of -0. 9396 ** ; varieties of high and stable yield high stability coefficient analysis and test points are varieties for breeding , demonstration match . Indicating that the high stability coefficient analysis method is simple , true and accurate response varieties of high and stable yield traits . Analysis of variance and regression analysis to test varieties of high yield and yield stability analysis of relative isolation , and more cumbersome computational analysis , which may occur in the analysis of the results inconsistent conclusions . HSC method the varieties yield and yield stability combine to reflect the new varieties of high yield and yield stability , high stability coefficient , its relatively simple calculation . Simply varieties of high stability coefficient can be derived by calculating the average yield of the species tested varieties and control , in order to determine the tested varieties of high yield stability . Therefore, the high stability coefficient analysis method is effective and reliable method of High Yield Stability Analysis of the Regional Trial varieties .
