Abstract

This experiment was conducted in the plastic houses, Department of Horticulture, University of Baghdad during the growing season of 1994-1995. The experiment was consist of the evaluation of field growth of some mutant chosen from the plant receving 20 and 25 krd and from the M2 which shows a changing from latement to indeterment growth which they are 61 mutants.
Seeds of these mutant were growen in Lath houses at 11-10-1994 and the seedling was transplanted to the plastic houses in 16-11-1994 with original plants as a contract plants. The study consist of yield and yield components. Vegetative growth and the qualitative characters of the fruits. The experimental results shows that many mutants significantly differ from the original plants and there are many differences between those mutants in the studied characters.
The mutant 19 which came from plants received 20 krd significantly overcome the other mutant in 13 characters, followed by the mutant 17 which overcome the other mutant in 10 characters and the mutant 4 in 9 characters. The mutant 19 gave the highest plant height of 309.5 cm and 15 truss on the on the in stem mutant 4 significantly gave the highest– early yield of 5.28 kg/ plant, total yield of 11 kg/ plant highest average fruit weight of 171.9 gm.
In plants received 25 krd, the mutant 23 significantly overcome the other mutants in 14 characters followed by the mutants 22, 30 which they are characterized by 13 characters. The mutant 25 significantly gave the highest plant height of 337.5 cm and gave 18 turss on the main stem, early yield and total yield of 4.15 and 9.12 kg/ plant respectively and average fruit weight of 121.3 gm. This mutant characterized by 7 characters specially yield, yield component and the vegetative characters.
As a result of this study we can recommended the mutants 19, 17, 4, 25, 26, 27, 28, 29 and 30 as promising mutants to be planted in the plastic and green houses and to compare them with the recommended varieties.
