In 17 F1 hybrid combinations involving 14 genotypes of pigeon pea, heterotic effects were analysed for yield, its components and some growth factors. Mean heterosis of 67% was obtained for yield, 96% for secondary branches and 80% for number of pods per plant. Latter two characters contributed maximum for the increase in yield. In general, medium × medium, low × medium crosses resulted in high heterotic performance. Genetic diversity was the key to obtaining hybrid vigour.
