Abstract
Wheat (Triticum aestivum L.) germplasm of one hundred accessions were demonstrated for Cluster and Principal component analysis, the experimental plot was conducted during the growing season 2006 in augmented field design at research area of the Department of Plant Breeding and Genetics, Faculty of Agriculture, Gomal University, Dera Ismail Khan, KPK, Pakistan. Data were collected and analyzed for different polygenic traits. Eigenvalues > 1 were noted for three PCs out of ten, having 29.02%, 43.42% and 55.00% of the total variability with positive effects for most of the traits. While rest of the traits expressed moderate to low variability. Scatter diagram also depicted a wide range of genetic variability for various traits on the basis of altitude and latitude. According to cluster analysis all the accessions were divided into three main groups A, B and C, which were further divided in to thirteen sub-groups. Cluster 1 of group A, on the basis of mean analysis four accessions were found with 4% population, has less days to heading (84.5 ± 2.65). The Cluster 2nd accounts for 13% of the population with thirteen accessions. In group B, two accessions were found in cluster 5 with a contribution of 2% for two accessions PARC/NIAR 2450 (02), PARC/NIAR 2771 (03), having minimum days to maturity (132.5 ± 0.71). Cluster 7 contributes 3% of the population with three accessions, has a maximum number of tillers plant-1 (18.6 ± 1.65). Cluster 9 was noted for 1% of the population with one accession (PARC/JICA 3849 (01)), has less days to emergence (7) and greater plant height (149.8 cm). While in group C, clusters 12 consists four accessions with 4% contribution, having high 1000-grain weight (42.02 ± 2.88). Last cluster 13 of group C, contributed 2% to the population with two accessions PARC/MAFF 4275 (01), PARC/MAFF 4280 (01), having large spike length (20.8 ± 2.62 cm), greater number of spikelets spike-1(29.3 ± 3.61), high grain yield plant-1 (3.96 ± 0.93 gm) and greater grain yield (kg ha-1) (5001 ± 261).
