Abstract: Study on 11 main characters of 10 barly cuhive was conducted with multiple statistics analysis.The results indicated that some the coefficient of variation was more than others in ears per mu,,ear length,and number of spike per plant ,the coefficient of variation were 23.81%,19.83%and 18.6% o while coefficient of variation of stages was 2,52%;some correlation were found that it was significant correlation between yield and stages and grain weight per plant. We found that cumulative was 83.43% among the 3 Principal components by principal components analysis, those correlation of characters showed ＂a result of multi-effect＂ and ＂multi-effect in heritability of quantitative trail,we should take into account the stages and grain weight per plant,simuhaneit, plant hight , ear length, main grains per spike should be seletion, for breeding objective of high yield and good quality .
