Breeding of a New Muskmelon Variety Tainan 9
Hwang, S. L.
A new F1 hybrid of muskmelon (Cucumis melo var. reticulates) variety Tainan 9 was released by the Tainan District Agricultural Improvement Station (DAIS) in 1992. The maternal line HG5-1-4-6-1-1 was selected in 1989 from the progenies of a cross also made in 1985 between Honey Dew and an inbred line G41115 selected at the Tainan DAIS. The parental line Tw3-2-6-4-1 was obtained in 1988 from the progenies of a cross also made in 1985 between the inbred line HG5-1-4-6-1-1 and TW3-2-6-4-1 were then crossed in the fall of 1989 to obtain the line Tainan Test Cross 78-13, i.e. the code number of Tainan 9 in the breeding process before naming. Due to its superior characteristics in the combining ability test, line comparison trials, regional trials, local trials, screening for resistance to powdery mildew and storage tests, the line 78-13 was selected and submitter to the Committee of Registration for anew Crop Variety of the Taiwan Provincial Department of Agriculture & Forestry, and was finally named Tainan 9 on 17 December 1992 at the Tainan DAIS. The characteristics of this variety include early maturation, more resistant to powdery mildew, medium fruit size with milk-yellow skin and light-green flesh, higher soluble solids content and longer shelf-life, oval-round fruit shape with fine and dense nets on the surface, and stable yield. It can also be grown under relatively higher temperatures with good quality.
