A Possible Source of Cytoplasmic Male Sterility in Intermediate Wheat-Grass, Agropyron Intermedium (Host) Beauv1
- Jurgen Schulz-Schaeffer2
Amphidiploid Triticum durum Desf. × Agropyron intermedium (Host) Beauv. and T. durum × A. trichophorum (Link) Richt. hybrids were backcrossed twice A. intermedium and A. trichophorum. A pronounced increase in male sterility was observed in the series from the amphidiploid (AD) to the first and second substitution backcross generations (SB1 and SB2). Male sterility estimates averaged 53.4% in the AD, 83.6% in the SB1 and 96.8% in the SB2. Approximately 69% of all SB2 plants were 99 to 100% male sterile.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
