For improving good yield and quality of cherry tomato, especially for high total soluble solid (%brix) and similar to the imported vartiety, the screened cherry tomatoes from The Royal Project Foundation were crosssed with those of the elited lines from Khon Kaen University. The experiment was designed for 3 years (2008-2010).For the 1st year experiment, base population was produced by gene pool from 22 parental pure-lines, and resulted in 16 single-crosses during October 2007-February 2008. All single-crosses were grown and compared to their parents during the rainy season (May-September, 2008). The results showed that many single-crosses showed good quality of fruit yield, i.e 101/508 and 501/506. The single crosses with good uniformity in fruit yield, fruit cluster and high %brix even under high temperature of low-land research station at Khon Kaen University were selected. They will beconfirmed under the high land research station of Royal Project Foundation during the cool season in the same year. The seed of their parental lines will be multiplied and produced the commercial hybrids for Royal Project Foundation thereafter
