KiiCHi MiYAKE and Yoshitake Imai :— On the Inheritance of 

 flower-color in Sisyrinchium angsti folium. 



Crosses were made between two races of Sisyrinchium angusti- 

 folium, which differ only in the flower-color. The flower of one is 

 bluish-purple in color, while that of the other is white with colored 

 centre. The color of the Fi flower is almost like that of the latter, 

 being white with colored eye. The white dominance, however, is 

 not complete, the colored central tips of the eye of the hybrid flower 

 being half way elongated towards the tips of the petals. As these 

 two color distributions are due to the single factor difference, the 

 segregating ratio is 1 : 2 : 1. In the Fg population, some dwarfs 

 have appeared, with which the genetic experiments are now under 

 way.
