Abstract

Efforts to improve papaya quality can be achieved by genotypes crossbreeding. The crosslines are expected to have superior quality compared to the elders. This study aims to get the information as regards character of the crossbreeding results in several papaya genotypes. This research was conducted in Saree Village, Lembah Seulawah, Regency of Aceh Besar and Horticultural Laboratory, Faculty of Agriculture, Syiah Kuala University from March to July 2017. This study used 11 genotypes of papaya as a treatment (4 elders are Calina (USK4), Carmida(USK6), Dapina (USK7), Carisya (USK1) and 7 genotypes were the crosslines). The design used was Randomized Completely Block Design with Non Factorial pattern. The number of crossline is 7, and 4 elders as a comparison, so there are 11 experimental treatments. Data analysis was performed by using Analysis of Variance (ANOVA) to determine the effect of genotypes tested. If the ANOVA test shows a real effect, then proceed with the Tukey Test at the 5% level (Tukey0.05). The results of this research showed there was a high diversity in the performance and character of papayas production from the crosslines to the comparison parents, and it was found that the genotype USK1 (elder) and USK1 X USK7 (crossline) are genotype that have the preferred quality of the consumer based on qualitative quality, organoleptic test and the measurement of the sweetness of the fruit pulp (13.40 and 11.89 Brix).
