Natural Crossing in Guar, Cyamopsis Tetragonoloba (L.) Taub.1

  1. R. E. Stafford and
  2. C. R. Lewis2



Detectable natural crossing between 21 glabrous breeding lines of guar grown with two pubescent breeding lines ranged from 0.3 to 4.4%. Maximum crossing probably approaches 9%, if undetected natural crossing within glabrous and pubescent lines is also considered. Natural crossing of this magnitude must be considered in maintaining genetic purity of breeding lines and in maintaining varietal purity of seed increases.
