STUDIES ON YIELD, COMPONENTS, FIBER AND SEED QUALITY IN SOME EGYPTIAN CULTIVARS
Rasha Mohamed Ahmed Teba;
Abstract
The present investigation was initiated to facilitate the utilization of commercial varieties in breeding for improving the Egyptian cotton germplasm by
1) Describing the genetic variations available for earliness, yield, yield components, fiber properties and c tton seed quality. 2) clustering seven commercial cotton varieties for the previous traits and identifying the best potential source material for breeding short duration, high yield, high seed quality varieties.
Seven commercial Egyptian cotton varieties (G. barbadense L.) four of them belonging to extra long stable, namely, Giza 45, Giza 70, Giza 87 and Giza
88 beside three long stable varieties Giza 85, Giza 86 and Giza 89 were used as a plant materials.
Field trials were conduced during the two successive years 2006 and 2007 in at the experimental farm of Faculty of Agricultural Saba Bash Alexandria University in randomized complete block design with three replications.
Seed cotton yield of first pick from the three inner rows for each plot was ginned and the resultant seeds were used for the determination of the following physical and seed quality traits.
The studied characters:
A. Earliness measurements.
Position of first fruiting node, Days to first flower, Days to first opening boll and Earliness index.
B. Yield and yield components:
