ABSTRACT

The results of crosses between the best pollen sources and various female wheat parents of different ploidy levels (hexaploid and tetraploid) indicated that hexaploid wheat perform better than tetraploid in crosses with maize. However, successful production of embryos at a relatively high frequency could be achieved in tetraploid wheats with FSH-399. The highest frequency of embryo formation (59.0%) was produced from a cross between the hexaploid wheat (F1 Cross-5) and maize hybrid FSH-399.
