  Ten elite wheat breeding lines were evaluated for yield and yield components under rainfed conditions at Peshawar. Genotypic and phenotypic associations between the characters and their direct and indirect effects on grain yield were analyzed. Plant height showed positive correlation only with spikelets per spike and was negatively correlated with the other studied characters. Positive correlation of tillers per plant was observed with all the traits except spikelets per spike. Spike length was found to be positively correlated with spikelets per spike and grain yield and negatively so with 1000-grain weight. Significantly negative correlation of spikelets per spike was observed with 1000 grain weight and grain yield. Correlation coefficient between 1000-grain weight and grain yield ha-1 was positive and significant. Overall tillers per plant, spike length and 1000-grain weight showed significant positive correlation with grain yield while plant height and spikelets per spike were negative and significantly (p<0.05) correlated with grain yield. Path analysis indicated that tillers per plant had the highest positive direct effect on grain yield followed by spikelets per spike and 1000-grain weight, whereas plant height and spike length had negative direct effect on this parameter.

  During 1997 to 98, the fertilizer level applied at the ratio of 1/3 as a basal + 2/3 at 30 days after planting significantly increased the yield and seed weight over other treatments whereas during 1998 to 99, all the splie applied treatments gave higher yield over full basal dose applied at planting, although, no significant difference appeared among them but generally the fertilizer applied in the ratio of ½ as a basal + ½ after 30 days of planting appeared the best. However response towards seed yield of both the above treatments may be the result of rainfall distribution at growing stage of the crop during both the years respectively.
