The linear canonical variate analysis (CVA), the overall assignments of individuals into their original groups was 95.13%. The morphometric and meristic analysis were fully congruent and confirm the occurrence of two potential differentiated groups. This variation of morphometric and meristic characters in ...

The PCA also revealed that morphological variations related to the characters of head depth, body length, body depth, caudal peduncle length and depth. In discriminant function analysis (DFA), the first two discriminant functions accounted for 72.00% of total variation, and discriminated fish samples into three major groups following to their collecting drainages.

Twelve morphological variables, grouped the population into 6 clusters. Common characters of palm belonging to cluster I are lower weights of fruit, nut and husk with shorter fruit equatorial diameter and shorter internodes. Palms belonging to cluster II have higher weight of nut and longer equatorial diameter. Palms of c...

Based on the Fourier coefficient, Fisher’s discriminant analysis accurately classified 76.2% specimens into correct stocks whereas the discriminant function of shape indices only correctly identified 62.8% specimens into right stocks. As the sagittae in L. haematocheilus had an irregular round shape ...

The results revealed that most (86.33%) of the soyabean marketers were between the ages of 31-60 years, about 83.33% of soyabean marketers had less than 5 years marketing experiences. Cost of transportation constitutes 47.56% of the total variable cost. Estimated costs and returns analysis gave the gross margin and gross income of N15,513,400 and N 16,249,000 per annum respectively. Estimated marketing mar...

Estimation of Different Genetic Parameters in Various Safflower (Carthamus tinctorius L.) Genotypes under Field Condition
...Analysis of variance and principal component analysis were carried out to estimate the extent of variability for studied parameters and to partition the germplasm into various cluster groups on basis of their mean performance. A value of 74% was indicated by the first three PCs, which showed the highest variability between studied parameters. Eigen values >1 contributed variability between the genotypes under field condition. Minimum and maximum heritabilit...

The eigenvalues of more than 60.8% accounted a total of 70% genetic variants. Finally, it was found that a high degree of variance was identified in all germplasm collected from Malakand sections with some additional unique characteristics, such as early cooking, high productivity and protein significance as compared to other parts of th...

Principal Component and Cluster Analyses as Tools in the Assessment of Genetic Diversity for Late Season Cauliflower Genotypes
...yses such as cluster and principal component analysis measures the amount of genetic diversity in respect of several charaters and asseses the relative contribution of different traits to the total variation. In the present study, nineteen genotypes were evaluated for presence of genetic diversity through principal component and cluster analyses. The experiment was designed in randomized complete block design with two replications at the experimental area of V...
