White flesh and red flesh pitaya fruit set percentage reach 100％ after three kinds of pollination treatments. However, no fruit set was obtained when red flesh pitaya flowers were self-pllinated as pollen could be germinate normally and could not reach ovule in vital effective period. Therefore, it was concluded as self-incompatibility flowering type. Pitaya fruit set reached 100％ when white flesh pollen was placed on stigma of red flesh pitaya. This proved that red pitaya has special hybrid compatability and could exhibit immediately via fruit metaxenia effect. In addition, weather condition is an important factor to fruit set when pollination process is proceeding. Growth of either white or red pitaya fruit set showed a sigmoid curve. As fruit grow longer, fruit shape goes rounder. In total soluble solid content, fruit heart was the highest than any other part of the fruit in all of the treatment. Red flesh pitaya fruit grown contained the highest total soluble than sample from other regions owing to sufficient pollen source. In pitaya thousand seed was heavier than other treatment of white flesh, however, the check was larger than other treatment of red flesh one. Hybrid white flesh fresh fruit weight of the highest among all of the treatment.
