Heterosis Of Yield Character And Fruit Fly (Bactrocera Dorsalis) Resistance On Chili

Fruit fly oviposition on chili fruit may cause considerable damage. Heavy attack of this pest will decrease both yield quantity and quality, and will affect the crop economic value. Using resistant variety is one of the ways to suppress fruit damage. This study was aimed at determining the heterosis value of the yield and fruit fly resistance. The research used Randomized Block Design that consisted of 15 treatments (9 F1 generations, 3 resistant parents and 3 susceptible parents) with three replications. A total of 990 chili plants was used in this study. Plant morphology was evaluated for plant performance (plant height, stem diameter, leave length, leave width, flowering date, fruit length, fruit width, fruit weight, yield per hectare) and fruit fly resistance. The results showed that the F1 generation had a better high yielding trait compare to the parents. For fruit fly resistance, F1 generations were more resistance than the susceptible parents. Index deterrent oviposition F1 generations were higher than susceptible parents. The heterosis phenomenon obtained in both characters, yield and fruit fly resistant.
