Fifteen pigeonpea hybrids developed by crossing four cytoplasmic-nuclear male-sterile (CMS) lines with nine fertility restorers were introduced from International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), India to Myanmar and evaluated at three locations. Hybrids ‘ICPH 2671’, ‘ICPH 2673’, ‘ICPH 2740’ and ‘ICPH 3497’ were found stable over the three environments and produced 1846 to 1967 kg/ha yield with 30.4 to 41.7% standard heterosis. ‘ICPH 3461’ (2217 kg/ha) was found suitable for Zaloke with 42.0% standard heterosis. In 36 on-farm trials, hybrid ‘ICPH 2671’ was 11.9 to 53.1% superior in yield over the control. The other promising hybrid ‘ICPH 2740’ (2247 kg/ha) also exhibited 70.0% standard heterosis in an on-farm trial conducted in Monwya township. Based on farmers’ preference and yield, ‘ICPH 2671’ and ‘ICPH 2740’ were selected for further promotion. The large-scale hybrid seed production programme was also successful with 1596 to 2931 kg/ha hybrid seed yield. The results of present investigations showed that pigeonpea hybrids have potential for enhancing production and productivity of pigeonpea in Myanmar.
