Genetic diversity play key role in the germplasm improvement which is directly correlated with the crop production. Various statistical techniques have been used to study diversity among different genotypes. Among these techniques multivariate is most frequently used one for the genetic association of genotypes. In the present study a total of 64 advance lines included one check cultivar were evaluated under the field conditions of Cereal Crop Research Institute, Pirsabaq Nowshera, Pakistan during September 2017. Data were recorded for nine different parameters. Multivariate analysis divided the total 64 genotypes into four groups. The first five PCs with Eigen values > 1 contributed 86.95% of the variability amongst genotypes. Characters with maximum values in PC1 were Spikelets spike^-1 (SPPS) (0.732), spike length (SPL) (0.722) and biological yield (BY) (0.607), PC2 comprised of 100-grain weight (TGW) (0.605), grain yield (GY) (0.482) while days to heading (DH) (0.393), for PC3 major contributors were BY (0.550) and number of tillers meter square^-1 (NTPS) (0.289), the contribution of PC4 were flag leaf area (FLA) (0.716) and SPL (0.298) and the maximum values for various traits in PC5 were SPPS (0.732), SPL (0.722) and BY (0.607). From the findings of present study best performing lines can be directly recommended for general cultivation or to be used in future breeding programs.

遗传多样性在种质改良中起关键作用，而种质改良与农作物产量直接相关。已经使用各种统计技术来研究不同基因型之间的多样性。在这些技术中，多变量最常用于基因型的遗传关联。在本研究中，于2017年9月在巴基斯坦Pirsabaq Nowshera的谷物作物研究所的田间条件下对包括一种检查品种在内的总共64个先进品系进行了评估。记录了九个不同参数的数据。多变量分析将总共64个基因型分为四组。本征值> 1的前五台PC在基因型中贡献了86.95％的变异性。PC1中具有最大值的字符是小穗峰值^-1（SPPS）（0.732），穗长（SPL）（0.722）和生物产量（BY）（0.607），PC2由100粒重（TGW）（0.605），谷物产量（GY）（0.482）组成标题（DH）（0.393），对于PC3的主要贡献是BY（0.550）和分till米数^-1（NTPS）的数量（0.289），PC4的贡献是剑叶面积（FLA）（0.716）和SPL（0.298） ），PC5中各种性状的最大值分别为SPPS（0.732），SPL（0.722）和BY（0.607）。从本研究的发现中，可以将性能最好的品系直接推荐用于一般栽培或用于将来的育种计划。
