| Abstract: | The genetic stability of variations of main agronomic characteristics in progenies from the regenerated plants of immature embryo culture in vitro was studied. The results showed that the variations of earliness in maturity, high 1000-grain weight, plant height and grain weight per spike were heritable and tended to be stable in IE3 and completely stable in IE4 The wide variation of main agronomic characteristics induced by embryo culture in vitro provided the probability of selection in wheat improvement. Some somaclonal lines with useful variations could be used directly in wheat production. |
