Abstract

Development of genotypes with desirable characters has been the main focus of wheat breeding programmes. An experiment comprising fourteen wheat breeding lines (most of CIMMYT origin) and two check cultivars was planted in randomized complete block design with three replications at the Agricultural Research Farm, NWFP Agricultural University Peshawar during 2000-2001. Data were recorded on yield and some other important plant characters. Statistical analysis of the data were carried out and the means were separated using he least significant difference (LSD) test. Phenotypic and genotypic correlation coefficients were also determined. Analysis of variance revealed that the genotypes differed significantly for days to 50 heading, height of the main tiller, spike length and total dry weight. However, differences were not significant for days to maturity, grain yield and harvest index. Days to 50% heading, height of the main tiller and days to maturity showed significantly positive phenotypic correlations with grain yield. Different genotypes expressed potentials for some traits but none had superiority in yield per se.
