ABSTRACT
One of the problems on melon production is the availability of superior melon seeds. The failure of flowers to form fruit often occurs in artificial pollination. It is caused by low viability and number of pollen and unpreparedness of the pistil during pollination. The aim of this study was to determine the effectiveness of pollination time and the proportion of female and male flowers on the hybridization sets of melon varieties. This study was conducted on January-May 2018 in screen house at Karangwidoro Village, Dau District, Malang. This study was done by cross-pollination between three varieties of melon (Melindo, Madesta and Glamour varieties). The highest percentage of successful hybridization among treatments was W1P1 treatment (pollination time at 6.00-7.00 a. m. and proportion of female and male flowers 1 : 1). The observation of fruit quality (size, weight and sweetness) in all hybridization sets showed different results. It was caused by the differences of pollen source (different varieties). The results of the t-test on the yielding characters indicated that ME x MD pollination set had significantly different results with ME selfing control. The pollination time at 6.00-7.00 a.m. and proportion of female to male flowers 1: 1 is the most effective hybridization method to increase successful hybridization and yield characters of melon.
