Evaluation of Indigenous Landraces of Ricebean (Vigna umbellata) from Nagaland for Growth and Yield Attributing Characters

Thirty landraccs of ricebean collected from different localities of Nagai and were field evaluated for growth, development and yield attributing characteristics. The landraces exhibited significant variations particularly for yield attributing characteristics like 100 seed weight, number of pods per plant, number of seed per pod and pod length. The 100 seed weight character had highest heritability (0.984) followed by number of seeds per pod and number of pods per plant. The 100 seed weight also had maximum direct effect on yield (0.683) followed by seed per pod, pod length and pods per plant.
