Comparative Study for the Relative Importance of Characters Contributing to Seed‐Cotton Yield in American and Egyptian Cottons

Comparative Study for the Relative Importance of Characters Contributing to Seed‐Cotton Yield in... The path coefficient analysis was employed to determine the contribution of boll number per plant, boll weight and seed index characters to the variation in seed‐cotton yield per plant, in the American and Egyptian cotton varieties; McNair 220 and Giza 75 respectively.

Abstract

The path coefficient analysis was employed to determine the contribution of boll number per plant, boll weight and seed index characters to the variation in seed‐cotton yield per plant, in the American and Egyptian cotton varieties; McNair 220 and Giza 75 respectively. Data obtained from yield trials carried out at Fayoum Experimental Farm, Faculty of Agriculture, in two growing seasons, 1982 and 1983, were used in this analysis. It was found that boll number per plant had the greatest contribution to seed cotton yield in both American and Egyptian cotton varieties. Selection for number of bolls/plant and boll weight in American Upland cotton accounts for about 75% of the yield. While in Egyptian cotton, number of bolls/plant and boll weight account for about 60% only of yield. The arrangement of the components contributing to plant yield, according to their relative importance in McNair 220 variety was: (1) The direct effect of bolls/plant. (2) The direct effect of boll weight. (3) The joint effect of number of bolls with boll weight. While in Giza 75 variety the arrangement was as follows: (1) The direct effect of number of bolls per plant. (2) The joint effect of number of bolls with boll weight. (3) The direct effect of boll weight.
