Multivariative analysis of some metric traits in bread wheat (Triticum aestivum L.)


Hafiz Muhammad Ahmad, Shahid Iqbal Awan, Omar Aziz and Muhammad Amjad Ali

Improved yield potential is a basic goal for plant breeders. Progress in yield potential results from the progressive accumulation of genes conferring higher yield or elimination of the unfavorable genes through the breeding process. Analysis of genetic diversity in germplasm collection aids in classification of genotypes and identification of core collections with possible utility for specific breeding goal. The nineteen genotypes were grouped into three clusters on the basis of average linkage. By performing analysis for PCs it was observed that variance for Eigen value was maximum (3.53) in PC-I followed by PC-II (1.97) and least for PC-III (1.16). Total variance percentage was maximum in PC-I (39.17) followed by PC-IIand PC-III which was same (21.89) and total variance exerted by three factors was 73.94. Distribution  pattern  of  all  the  genotypes  into three clusters showed the presence of considerable genetic diversity among  the genotypes  for  most of the traits  under consideration. The mean values for days to 50% Heading (167), No of tillers/plant (4.74), No of spiklets/spike (15.46), biological yield (148), Grain yield (48.48) and  harvest index (32.82) was  highest in cluster-I. Cluster-II exhibited the maximum mean value (7.72) for spike length, average values for plant height and 1000 grain weight was higher in cluster-III.
