Abstract

Genetic variability is the main basis of improvement in crops. An experiment comprising fifteen old and new wheat varieties was planted in randomized complete block design with three replications at the Agricultural Research Farm of NWFP Agricultural University, Peshawar during crop season, 2003-2004. Data were recorded on yield and some other morphological traits. Statistical analysis of the data was carried out and means were separated using the least significance difference test. Correlation coefficients were also determined. Analysis of variance revealed that the varieties differed significantly for days to 505/v heading, days to 50% anthesis, plant height and grain yield ha -1. However, differences were non-significant for physiological maturity, biological yield and harvest index. Days to 50% anthesis showed significantly positive correlations with days to 50% heading, days to maturity and grain yield. Grain yield also exhibited significantly positive correlation with biological yield.
