Traits selection criteria for genetic improvement of grain and leafy Amaranth (Amaranthus spp) using Principal Component Analysis

Grain Amaranths are important nutritional vegetables in the world for their grains and leaves. Twelve grain Amaranth accessions were evaluated performances using randomized complete block design with 3 replications 2 years to measure variability group accessions. Analysis of Variance revealed significant among Amaranths. Phenotypic variances higher magnitude than genotypic variance all traits studied. High genetic advance was obtained characters except 1000 weight (23.61). The coefficients variations lower phenotypic coefficient variations. Heritability ranged from 41.08% yield/plot 62.18% plant height at flowering. yield positive highly significantly correlated weight, leaf area but length width. PCA four main components representing 78.06% total 12 amaranth identified as strongly three principal components. PC1 is well-correlated Plant flowering, Stem girth, Number leaves, maturity, width, length, Petiole length. bi-plot analysis classified accession NG/AA/03/11/010, NGB 01259, 0127 having good desired traits, Accession NHGB/09/108, NG/AO/08/04 01261 grouped better attributes, while 01234, NHGB 09/09 NHAC3 dual purpose yield.
