EFFECT OF SELECTION AND INBREEDING ON BULB FLESH COLOR IN THE ONION CULTIVAR GIZA 20

Abstract
This work was carried out at Shandaweel Experimental Station, Agricultural Research Center, Sohag Governorate, Egypt from 1994 to 1998 seasons to study the effect of two cycles of selection on flesh color of the onion variety Giza 20. Full and half sibs progenies had more white fleshed bulbs than parental selected whites immediately detected after cutting. This also occurred in progenies of white mother bulbs detected a week after cutting in the second selection cycle full sibs. Predicted genetic advance due to selection was more than realized in the progenies of white fleshed first cycle. Moreover, realized genetic advance due to selection for white-fleshed bulbs was less than predicted in the progenies of pinks and parental detected a week after cutting, (second cycle). Accordingly, it is practically possible to produce Giza 20 bulbs completely free from any pink color if two cycles of selection were conducted and arising plants selfed.
