Discrimination of maize (Zea maysL.) inbreds for morphophysiological and yield traits byD2 statistics and principal component analysis (PCA)

Abstract: To discriminate maize inbred lines based on morpho-physiological and yield traits using D 2 statistics and principal component analysis (PCA), fifty five genotypes available at Department of Genetics and Plant breeding, Sam Higginbottom Institute of Agriculture Science and Technology, Allahabad were tested during Rabi 2013-14 under irrigation condition in Randomized Block Design with three replications. Analysis of variance revealed significant differences for 18 characters studied among the genotypes. The D 2… Show more

“…It also had negative non-significant correlation with days to fifty per cent tasseling (-0.146, -0.056), days to fifty per cent silking (-0.070, -0.045), anthesis to silking interval (-0.194, -0.185) and cob length (-0.014, -0.014) at both genotypic and phenotypic levels, respectively. These results are in consonance with Pavan et al, [8]; Bhusal et al, [9].…”

“…A detailed understanding of the magnitude and pattern of genetic variability is required for the improvement of any crop. Plant breeders have thus employed several multivariate techniques including Metroglyph and Principal Component Analyses (PCA) to profi le the variability within the germplasm of diff erent crops (Aremu, 2011;Nwangburuka et al, 2011;Osarawu et al, 2013). Anderson (1960) proposed Metroglyph analysis, a technique that reveals patterns of morphological variation in crop species by reducing the complex interrelationship among accessions into a pictorial scatter…”
