Pengujian Daya Hasil Pendahuluan Kacang Sayur Hibrida Ungu Pada Dua Lokasi Yang Berbeda Agroekosistemnya

Abstrak

This purple-pod vegetable bean has been selected until the seventh generation so it has shown a high enough uniformity, the color of the pod is more than 95% purple. The color of the purple pod is closely related to the anthocyanin content. The more purple the pod color indicates the higher the anthocyanin content. Therefore, it is necessary to test the preliminary yield abilityof several selected vegetable bean lines at two different agro-ecosystem locations ie on dry land and on paddy field to see index of sensitivity and adaptation. These hybrid vegetable beans are obtained by hybridization between cowpea species (Vigna unguiculata L. Walp.) Local varieties of NTB with long beans (Vigna sesquipedalis L. Fruwirth). The long-term goal of this research is to obtain new superior varieties of purple hybrid vegetable bean with high Protein and Anthocyanin content, tolerance to drought, without any lanjaran in the cultivation system and high production. This research activity is a series of previous research that has been done in the form of hybridization between cowpea with long bean followed by selection until the seventh generation. Ten lines have been planted for testing on dry land in Kayangan District of North Lombok Regency and rice fields in Narmada District, West Lombok regency. The observed characters were pod color, number of pods per plant, pod length, pod diameter, pod softness, fresh pod weight, number of seeds per pod, stem diameter, number of productive branches, and harvest age. The hybrid  bean number 85 (KH85) has the highest yield compared to other lines but is not significantly different from that of the hybrid bean number 51 (GKH51); 2). The genetic diversity coefficient is in the range of 7.04 to 46.30 %. The significance of heritability is 17.9 to 86.2 larger than the narrow sense of heritability ranging from 11.8 to 67.9; 3). The number of pods per plant has a significant positive correlation to the yield so that it can be used as a selection criterion to improve the yield ability
