Abstract

The experiments were conducted to study hexaploid wheat and tetraploid durum wheat and male sterile line of wheat crossing with maize.The hybrid embryos of immature embryonic age of 14 days and size of 0.4-1.0 mm were taken on 1/2MS media in vitro,24-25 ℃ for 2-3 weeks in dark and(26±1)℃ illumination for 1 800-2 000 lx.The results show that the rate of hexaploid wheat embryonic induced by pollen of maize was 5.4%,and much more than that of tetraploid durum wheat;the rate of wheat embryonic of male sterile line induced by pollen of maize was 3.2%,and much more than that of check;the rate of wheat embryonic induced by mixture pollen of different varieties of maize was 4.6%,and much more than that of pollen mono-variety of maize.The percentage of plantlet formation with age of 14 days and size of 0.4-1.0 mm taken on 1/2MS media in vitro with no hormone is 81%,more significant than that of others.
