In 1982, 116 single or multiple crosses were made among predominatly AVRDC
selections with high yield potential, higher levels of resistance to disease,
and uniform maturity. Thirty-nine additional crosses were made to incorporate
resistance to beanfly and to study inheritance of Cercospora leaf spot (CLS)
