Abstract
Study of Heritability and Heterosis on Hybridization between Cowpea and Longbean. Lestari Ujianto, Idris, and Uyek M. Yakop. The objectives of this research were to study the success rate of crossing and heritability on interspecific hybridization between several NTB local varieties of cowpea and several varieties of long bean. This research consisted of 3 stages i.e. (1) hybridization between cowpea and long bean; (2) Kata kunci: Persilangan, heterosis, heritabilitas, persilangan antarspesies. evaluation of F1 generation; (3) backcrossing between F1 with both parents. The observed data is analyzed to estimate the degree of crossability, value of broad sense heritability, coefficient of genetic variance. The result of this research indicated that: (1) interspecific crossing between cowpea NTB local varieties and long bean have different degree of successful with range 31 to 57% as well as on back crossing degree of successful with range 35 to 61%; (2) the characteristic of pod length and plant height indicated the high broad sense heritability value, and (3) there was hybrid vigor for diameter of pods on all cross combinations with heterosis and heterobeltiosis values ranging 11.4-27.0% and10.1-18.9% respectively.
