“…For many years, plant breeding programs depended on selecting genotypes by analyzing each agronomic variable individually, estimating genetic parameters, applying selection indices for traits and analyzing the environments to check the genotype x environment interaction. In recent years, multivariate methods and mixed models have become more important due to advances in computer software, and are being applied to evaluate genetic divergence (Costa et al, 2006;Oliveira et al, 2008;Bizari et al, 2014), select genotypes and progenies (Vianna et al, 2013;Dallastra et al, 2014), study adaptability and stability of genotypes (Maia et al, 2006;Mendonça et al, 2007;Borges et al, 2010b;Gomez et al, 2014), estimate genotypic values and study genetic parameters (Duarte et al, 2001;Lopes et al, 2008).…”

The objective of this study was to select soybean genotypes derived from crosses between conventional and transgenic lines Roundup Ready (RR), using jointly Restricted Maximum Likelihood/Best Linear Unbiased Prediction (REML/BLUP) approaches, factors analysis and principal components analysis, processed with favorable agronomic traits, during the 2013/2014 growing season. Three agronomic selection processes were identified to select genotypes that discriminate genotypes containing more specific properties. Process 1 (insertion height of first pod, HFP; number of branches, NB; number of pods, NP; number of nodes, NN; and grain yield, GY) was efficient to select earlier, smaller genotypes with good yield/production components and lodging resistance. The junction between mixed model via REML/BLUP and the applied multivariate statistic using factor analysis helped to select suitable genotypes with high performance to carry on the soybean plant-breeding program.

“…The number of individuals in each group varied in both the environments. Earlier studies (Silva et al, 2005;Lopes et al, 2008) reported variation in the number of groups and genotypes within each group according to environment. The variability for cane height, cane diameter and single cane weight were found out by PCA.…”

The present investigation aimed to assess the nature and magnitude of genetic divergence available in the Hybridization Block (E1) and National Hybridization Garden (E2) of ICAR-Sugarcane Breeding Institute, Coimbatore and to select the suitable diverse genotypes as parents for further utilization. Principal component and hierarchical cluster analyses were carried out in sixty eight genotypes with nine traits. In E1, the first three principal components explained about 73.45 per cent of the total variability and remaining six components accounted 26.55 per cent of variability. The PC 1 explained a maximum variability of 44.85 per cent followed by PC 2 and PC3. In E2, the first three principal components explained about 76.71 per cent of the total variability among the genotypes and the remaining six components described 23.29 per cent towards the total diversity. Nineteen clones viz., Co 0314,
