Wheat Campodoro, Orso, Penjamo 62 and Cumhuriyet 75 were grown in field trials near Cukurova, Turkey in 1976-8. 200, 300, 400 or 500 seeds/m2 were sown in the 1st or 3rd wk. of Nov. or the 1st wk. of Dec. The number of fertile ears was unaffected by date of sowing; Cumhuriyet 75 had the lowest number (498 fertile ears/m2) and Campodoro the highest number (562). The number of fertile ears/m2 increased with increase in sowing rate. Significant positive correlations were found between grain yield and number of fertile ears, 1000-grain wt., grains/ear, hl wt. and harvest index. Significant negative correlations were found between grain yield and tillers/plant and heading to ripening period.
