| Abstract | ||
| The study was carried out during the summer of 2000, as (2×4) factorial experiment according to randomize complete block design, with three replicates, using two cotton varieties. The first factor consists of two varieties, Ashor and coker 310, while the second factor consists of four levels of gamma radiation (0 , 10 , 20 and 40 Krad). Ashore cultivar was significantly superior than coker 310 in: boll weight and seeds index, while coker 310 cultivar was significantly superior in: No. of days to first boll opening. No significant difference between the two cultivars were appeared in: no. of vegetative and fruiting branches, no. of nodes following first fruiting branches, no. of days to first flower opening, no. of bolls/plant, no. of seeds/boll, seed cotton yield/plant and ginning out-turn. Different doses of gamma ray showed significant difference in: no. of fruit branches/plant, the nodes following first flower and boll opening, bolls weight, no. of seeds/boll, seed index, and seed cotton yield/plant. The two factors showed some significant interactions in some traits. | ||
