YosHiTAKA Imai : — Genetic Studies in Morning Glories. IV. 



There are several cliflFerent genetic types in the white-flowered 

 Japanese morning glory. The most common types of the white 

 flower are those relating to the so-called complementary factors in 

 color formation. White flower with green stem x colored flower with 

 colored stem and white flower with colored stem x colored flower 

 with colored stem gave both Fi of colored flower with colored stem, but 

 in the subsequent generation they segregated into colored and non- 

 colored forms, just like the respective parents, in monohybrid fashion. 

 White flower with green stem x white flower with colored stem gave 

 the colored flower with colored stem and the Fo generation composed 

 of 9 colored flowers with colored stem and 7 whites with either 

 green or colored stem. 



In an F3 family of a cross, white flower with colored stem x 

 blue-spotted flower (cream ground color) with spotted stem, were 

 found some green-stemed white flowers which are considered as very 

 rare, due to the crossover occurring between certain factors. The 

 genetic aspect of the origin of these white flowers is very complex, 

 and is explained in some detail. 



Another white flower with green stem which has appeared in 

 the progeny of a colored flower is found to be due to the "combina- 

 tion of three recessive factors that is indifferent to the so-called 

 comj)lementary factors.
