Efficient hybridization techniques are needed under field conditions to exploit the genetic potential of mungbean. A new technique was developed in which only upper half of the floral bud was opened to expose the stigma. The proper emasculation and pollination times were from 5 to 7 p.m. and 7 to 9 a.m., respectively. The success rate of crossing using this technique in Faisalabad, Pakistan averaged 62.8 percent and 20.0 percent in summer and spring, respectively. The crossed pods bore on the average 6.8 seeds per pod in summer and 5.0 seeds per pod in spring. This high success rate is mainly due to less disturbance on style and ovary in the bud during emasculation.
