Utilization of local cayenne pure lines for F-1 hybrid breeding program

Local cayenne can be used as a good genetic material for F-1 hybrid variety. The purpose of this research was to analyze and estimate general (GCA) and specific combining ability (SCA), heterosis, and heterobeltiosis value, then to evaluate and select F-1 progenies. The research was conducted from February to December 2019 at Indonesian Vegetables Research Institute, Lembang, (1,250 m sal). The genetic material consisted of six local cayenne lines i.e.: BNT, GNY, SGT, BGJ, HIU, MDN, 15 F-1 progenies, and STK as a commercial variety. The results showed that: (1) BGJ line had the highest GCA value on weight per one fruit (0.74), fruit length (0.77), fruit diameter (0.57), and fruit weight per plant (13.83), while the highest GCA value on fruit number per plant was MDN line (35.69); (2) F-1 SGT x HIU had the highest SCA value onr weight per one fruit (0.27), fruit length (0.56), and fruit weight per plant (69.90), while the highest SCA values fruit diameter (0.48) and fruit number per plant (129.29) were obtained by F1 HIU x MDN and F-1 BGJ x HIU respectively; (3) F-1 BNT x MDN, F-1 SGT x HIU, F-1 BGJ x MDN are recommended as advance hybrid lines.
