520 _aGurma melon is classified as a vegetable crop. For a long time, no attempts were made to improve its characteristics or to develop new varieties. In this respect. five inbred families of gurma melon in SGurma melon is classified as a vegetable crop. For a long time, no attempts were made to improve its characteristics or to develop new varieties. In this respect. five inbred families of gurma melon in S₄ generation were selected in an earlier study through self-pollination and selection program for the commercial cultivar. In this investigation these families were selfed to obtain the S₅ and S₆ generations and consequently, they were developed as new inbred lines, and they were compared and evaluated with the commercial cultivar. The results showed that the ranges of all studied traits for all lines became smaller in the 56 generation than those in the S₄ generation. At the same time, the means of the selected plants were changed every generation for all studied traits, e.g., the means of seeds weight /fruit and 100-seed weight were increased. The results also indicated that most new lines were significantly increased in comparison with the commercial cultivar for number of fruits/plant, seeds weight/fruit, 100-seed weight, yield/plant and yield/fed., while the commercial cultivar had the highest values of plant fresh weight, stem length, number of branches/plant and fruit weight. Generally, the results showed that selection program was very efficient to give desirable new lines for gurma melon. Gurma melon is classified as a vegetable crop.

In this investigation these families were selfed to obtain the SGurma melon is classified as a vegetable crop. For a long time, no attempts were made to improve its characteristics or to develop new varieties. In this respect. five inbred families of gurma melon in 54 generation were selected in an earlier study through self-pollination and selection program for the commercial cultivar. In this investigation these families were selfed to obtain the 55 and 56 generations and consequently, they were developed as new inbred lines, and they were compared and evaluated with the commercial cultivar. The results showed that the ranges of all studied traits for all lines became smaller in the 56 generation than those in the 54 generation. At the same time, the means of the selected plants were changed every generation for all studied traits, e.g., the means of seeds weight /fruit and 100-seed weight were increased. The results also indicated that most new lines were significantly increased in comparison with the commercial cultivar for number of fruits/plant, seeds weight/fruit, 10Q..seed weight, yield/plant and yield/fed., while the commercial cultivar had the highest values of plant fresh weight, stem length, number of branches/plant and fruit weight.
