The aim of this study was to evaluate different rootstocks for improving triploid seed production of the dessert watermelon, Citrullus lanatus. This 2-year study was conducted at two locations, in open fields at Antalya and Adana, Turkey, during the 2016 and 2017 growing seasons. | Turkish Journal of Agriculture and Forestry Turk J Agric For (2018) 42: 298-308 © TÜBİTAK doi: Research Article Rootstock capacity in improving production and quality of triploid watermelon seeds 1, 1 1 İlknur SOLMAZ * , Nebahat SARI , Mohamed Dhamir KOMBO , 2 1 1 İsmail ŞİMŞEK , Suhayb HUSSEIN , Mihriban NAMLI 1 Department of Horticulture, Faculty of Agriculture, Çukurova University, Adana, Turkey 2 Antalya Tarım Productive, Consultant and Marketing Co. Antalya, Turkey Received: Accepted/Published Online: Final Version: Abstract: The aim of this study was to evaluate different rootstocks for improving triploid seed production of the dessert watermelon, Citrullus lanatus. This 2-year study was conducted at two locations, in open fields at Antalya and Adana, Turkey, during the 2016 and 2017 growing seasons. The tetraploid watermelon line ‘ST 101’ was used as the female parent scion and the diploid line ‘WL 92’ as the male parent. Both parental lines were grafted onto three different rootstocks to determine the effect of grafting on seed yield and quality of triploid watermelon. Nun 9075, a Cucurbita interspecific hybrid (Cucurbita maxima × Cucurbita moschata), Argentario (Lagenaria siceraria), and citron watermelon PI 296341 (Citrullus amarus) were used as rootstocks. Nongrafted ST 101 and WL 92 were also crossed to be used as controls. The graft combinations and controls were compared for performance as measured by length, diameter and number of nodes of main stem, total yield, mean fruit weight, fruit length, fruit diameter, seed yield, number of seed per fruit, weight of 1000 seeds, seed germination and emergence percentage, days to germination and emergence, and seed coat and embryo weight ratio. Nun 9075/ST 101 and Argentario/ST 101 graft combinations resulted in longer main stems; increased total yield; heavier, longer, and wider fruits; and .
