Seleksi Populasi Generasi Ke-2 (F2) Hasil Persilangan Pepaya Callina (IPB9) dan Carisya (IPB3)

Abstract

Papaya (Carica papaya L.) is known as valuable fruit, because of it high nutrientcontent and economic value. Hybrid variety of papayaresultedfrom breeding program is still limited in Indonesia. The objective of this study is to describethe second generation of papaya population generated from crossing between Callina (IPB9) and Carisya (IPB3) to find a new genotype in the small size of fruit (500-700 g). Path analysis is used for weight, width, length, total soluble solution (TSS), flesh width, seed weight, total acidity, vitamin C, and weight of 100 dry seed. The fruit length, fruit width, flesh width, and seed weight showed positive correlation on fruit weight but total soluble solution (TSS) and seed weight had negative correlation. Fruit length give highest (0.64) direct effect on fruit weight then followed by fruit width (0.32) and seed weight (0.22).These characters can be used for selection trait on small size of papaya (500-750 g). The second generation population at Center for Tropical Horticulture Studies have the opportunity become a new variety.Keywords: length, path analysis, weight, width
