영문 초록

To study the inheritance of the gene for the growth habit of barley cultivars, F₁ and F₂ generations of the crosses between 61 spring barley varieties which included 53 Korean native varieties, and 8 recommended varieties and two winter barley varieties were grown in the greenhouse with 15℃-20℃ (night-day) and 24 hour-day length condition, and date of flag-leaf emergence were counted. Spring habit was controlled by the genes sh, Sh₂ and Sh₃, which are allelic to Sh, sh₂ and sh₃, respectively, controling winter habit. The genes for the spring habit were dominant over the gene for winter habit. Among 53 Korean Native varieties, 16 varieties showed to have one pair of dominant gene for spring habit or Sh₂Sh₂, another 16 varieties also appeared to have one pair of recessive genes for winter habit or shsh, only one variety had two pairs of dominant genes or Sh₂Sh₂Sh₃Sh₃ and 20 varieties possessed both one pair of dominant and one pair of recessive genes or shshSh₂Sh₂. All of 8 recommended varieties including four of six row covered barley and four of two row malting barley were appeared to have one pair of recessive gene for winter habit or shsh.
