    Abstract

    The research aimed to study effect of pollen sources, in artificial pollination, on crossing ability and yield of dragon fruit and to study the form and amount of chromosomes in 4 species of dragon fruit. All the 4th species were crossed each others in dialel completed mating system. Artificial pollination was held using paintbrush during the night started at 12.00 a.m. until in the morning (at 5.00 am) with brushing the paintbrush on the anther and then were pollinated on the stigma. White and yellow dragon fruit are self-compatible, while red and purle dragon fruit are self-incompatible. All of 4th species could be crossed intra and inter species with highly crossing ability. Both selfing pollination (used pollen from the same flower) and croosing pollination (used pollen from other species) produced fruit. But to produce better fruit, it is best to use pollen from different speciesand same genus. White, red and purple dragon fruit are diploid (2X) with the number of chromosomes 22, and yellowdragon fruit is a tetraploid plant (4X) with the number of chromosomes 44. There are 2 chromosomes form in dragon fruit, metacentric (M) and sub-metacentric (SM). White and purple dragon fruit its karyotype is 2N = 2X = 11 M, Red dragon fruit karyitype is 2N = 2X = 10 M + 1 SM. While the Yellow dragon fruit its karioyipe is 2 N = 4 X = 44 = 10 M + 1 SM. Key words: Crossing ability, chromosome, dragon fruit.
