S. IKENO : 



us cleai'ly to underetand the genotjpic Constitution of all colour-varieties used 

 in luy experiments, except some few races. Tlie tehavioiu- of the various 

 hj'brids of flesh-coloiu-ed race was studied till F^, and I tliiuk I am now able 

 to make a certain conclusion about its genotrj^ic constitution, but since my 

 expeiimental results concerning this race are not yet complete, I will defer 

 their publication to a futiu-e paper. 



Flower-Colours, 



The following colom-vaiieties were used in my experiments, viz. white, 

 yellow, orauge, flesh-colom'ed, red, and magenta (PI. II). Besides, I could 

 distinguish clearly two kinds of white, which are almost alike in external 

 appearance, and yet geuotypically diUerent ; the^- are called here tu/iite-I and 

 whitc-I'I respectively (PI. H, fig. 7-8).' 



The coloui-s of all parent varieties as well as their i^i-hybrids were 

 recorded by means of " Klincksieck et 'Wvlette, Code des Coulems " (Pai-is, 

 1908); the results are indicated in the foUowiug Table : — 



Table of Coloi-rs. 



1 I think that I have discovered still another ri^oe of white, which is externally quite 

 similar to white-I, and yet genotypically different from it. I will call it rrläk-lU; its behaviour 

 will be described below (p. 120).
