GENOTYPIC VARIATION FOR YIELD AND YIELD RELATED TRAITS AND THEIR CORRELATION STUDIES IN WHEAT

Abstract

ABSTRACT The main basis of improvement in crops is the development of desirable genotypes. An experiment consisting of fifteen wheat genotypes was planted in Randomized Complete Block Design (RCBD) with three replications at the Agricultural Research Farm, Malakandher, NWFP Agricultural University Peshawar during 2003-04. Data were recorded on some important yield related traits. Statistical analysis was carried out and the means were separated by the Least Significant Difference (LSD) test. Significant differences were observed among the genotypes for the number of productive tillers m -2 and grain yield. However, the differences were not significant for the characters of grains spike -1 , spikelets spike -
