Germplasm Phenotype:

• AT3  — Reduced seed set. Indehiscent anthers.
• CS8051  — outer walls of the four meiotic products of a pollen mother cell are fused and the pollen grains fail to separate, forming pollen tetrads; pollen viable and fertile, and fertilization with a single tetrad usually yields four seeds.
