标题：GENETIC RELATIONSHIP AND VARIABILITY AMONG INDONESIAN PURIFIED LOCAL LINES OF BAMBARA GROUNDNUT (Vigna subterranea (L.) Verdc.) BASED ON MORPHOLOGICAL CHARACTERS.
摘要：Bambara groundnut is one of alternative food in Indonesia. This research was conducted to evaluate genetic relationship and variability among 50 purified local lines based on morphological characters. The local lines were collected from plantation center areas. Purification of collected lines was done based on pod and seed characters. Evaluation of genetic relationship and variability were conducted using 50 purified local lines.Twenty plants from each line were planted in polybag without replication. Observation on individual plant based on IPGRI guidelines with some improvements. Genetic relationship on qualitative characters was analyzed by cluster analysis based on simple matching coefficient. Whereas variability analysis on quantitative characters was done based on genetic coefficient of variation. Evaluation of genetic relationship showed that at genetic similarity level 0.695, fifty purified local lines of bambara groundnut have been divided into two groups, each consisted of 45 lines and 5 lines respectively. The cluster analysis in the line showed no uniform lines. Variability analysis among 50 purified local lines showed that genetic variation was narrow. Furthermore, genetic variation within lines showed that 50 purified local lines had narrow variability on 21 characters and had narrow to broad genetic variation on 3 characters that have been observed. High variability on qualitative characters was found both within and among the purified local lines
