Alien Chromosome Controlling Sporophytic Sterility in Common Wheat1

  1. S. S. Maan2

Abstract

Abstract

Common wheat plants (Triticum aestivum L. em Thell.) having a monosomic or a disomic substitution (2n=42;20″+l′+l′ or 2n=42;20+l″, respectively) of an Aegilops longissima S. & M. chromosome were crossed as males to a set of ‘Chinese Spring’ telosomic or isosomic stocks. F1 plants were examined for kernels/spike, meiotic chromosome number, and chromosome pairing relationships. Results indicated that: 1) the afien chromosome was homoeologous to and substituted for 4A of wheat, 2) the missing wheat chromosome arms did not influence the sporophytic control of sterility of F1 plants, and 3) the male gametes without the critical alien chromosome were not transmitted.
