• High sterility of the hybrid Avena longiglumis×A. strigosa is caused by irregular and multiple associations of meiotic chromosomes. By free pollination, however, it gave 22 F2 seedlings with 14, 15 and 16 somatic chromosomes. Of them 15 plants (2n=14 and 15) survived to maturity. Based on the results of cytological and morphological observations a few plants seemed to recover almost similar chromosome component to that of the parents. The others clearly exhibited mixed traits of both parents as ever. Seed fertility of the F2 plants appears to be much dependent on the number of ring bivalents.
