Abstract
Three tomato varieties named no. 10 (I); bison (II) and Kecskement (III),as well as their crosses and their reciprocal crosses were irradiated and involved in this investigation. Variety (II) was the earliest in flowering, The shortest stem with the least number of branches per plant. Whereas variety (III) was the latest latest in flowering, the longest stem with the highest number of branches per plant. Meanwhile, variety (I) was in the intermediate between the other 2 varieties. Generally, days for 50% flowering were decreased for all varieties and all genotypes as a function of gamma irradiation. This response reached the maximum in M2. Whereas, plant height and number of branches did not gain the same trend. Variety (I) produced the highest number of fruits per plant, while variety (III) gained the lowest. The average weight of fruit was in reversal correlation with the average number of fruits per plant. All crosses and their reciprocal crosses were almost intermediate between their parents in number of fruits per plant, average fruit weight, fruit yield per plant, and seed setting per fruit. Irradiating seeds of tomato varieties and expected crosses stimulated the fruit characters, however, they were still less than the best parent.

C except the crosses (I x II), (I x III),(II x III) and (III x II) which overcame their original parents, particularly in M2. Meanwhile all crosses, as well as, their reciprocal crosses could not gain the prominancy in both lycopene and carotenoids over the best parent. Vitamin. C, and lycopene in fruits were decreased decreased in fruits as a function of gamma irradiation. (Abstract Truncated)}
