HE flax varieties grown on the largest acreage in desert T areas of California are susceptible ,to Fusarium wilt (Fusarimn oxysporzlriz f . hi (Bolley) Snyder and Hansen). These varieties are Punjab (C.I. 20) , now relatively unimportant, and Punjab 47 (C.I. 1 1 1 5 ) and Imperial (C.I. 1114), both selections of Punjab. Although wilt has not caused serious economic loss, the disease is increasing, and some fields are infested to a point whzre susceptible flax varieties can no longer be grown. Coincident with efforts to find resistant materials in local and introduced varieties (10, 11), a breeding program has been underway to develop resistant varieties by hybridization and backcrossing. Dakota (C.I. 1071) selections have been used rather extensively in this program. This report includes data obtained from crosses of one of these selections with Punjab, Punjab 47 and a second Dakota selection.
