The evaluation of cross progeny between Elite lines and commercial hybrid ‘Negeen’

The development of fruits without fertilization called parthenocarpy. Interacting genetic and physiological factors can affect parthenocarpy. In previous research superior lines of cucumber with high general combining ability which able to produce superior hybrids with high heterosis released but the lines have no enough parthenocarpic fruits. In this study, the possibility of crossing elite lines with commercial hyrid cv. Negeen studied and their progeny evaluated. Commercial cultivar 'Negeen' used as donor parent. Experiment conducted in complete randomized block design with three replication and characteristics including the number of parthenocarpic fruits, number of male flowers, number of lateral branches, percentage of parthenocarpic fruits, percentage of male flowers evaluated. Results showed that progeny of commercial cultivar 'Negeen' with B10 had the maximum number of parthenocarpic fruits. The minimum number of male flowers related to the progeny of commercial cultivar 'Negeen' with A10. The progeny of commercial cultivar 'Negeen' with A10 had the least of lateral branches. The maximum and minimum percentage of parthenocarpic fruits related to the progeny of commercial cultivar 'Negeen' with B12 and A10 and the progeny of commercial cultivar 'Negeen' with B10 respectively. Maximum and minimum percentage of female flower related to the progeny of commercial cultivar 'Negeen' with B10 and B12 respectively. According to these result it is possible to release recombinant inbred lines similar to elite lines with parthenocarpic in future.
