Abstract
Intercross between glyphosate sensitive and tolerant biotype of field bindweed and self pollination of each biotype were made. Seed set percentages of both biotypes by intercross were almost 100%. Seed set percentage by self pollination in sensitive biotype was 2.1% and that of tolerant biotype was 30.8%. Partial breakdown of self-incompatibility in glyphosate tolerant biotype of field bindweed was suggested.
