flowered ones in the early grovip, Tliis suggests some correlation between the 
flower color and the flowering time. 
4. The ratios of poles to dwarfs is approximately 3 : i in total, and when 
considered in two separate groups, the ratio also holds the same in each. So 
we may conclude that there is no correlation between the stem character and 
the flowering period. 
5. We do not see any difference between the progenies of reciprocal 
crosses. 
6. The \-ariation range of the progeny of the late variety G. P., is dis- 
tinctly wider than that of the I, P. j^rogeny. We had noticed a similar fact 
already in the previous year, but did not pay much attention to it. And the 
frequency distribution of G- P- was quite different from that in ordinary 
fluctuating variation. In the ordinary variation, the mode must lie in about 
the middle of the range, and towards both sides of the mode the frequencies 
must decrease gradually, but in this case, the frequencies in the class 64, 
situated in about the middle of the variation range, are remarkably small, 
while in the classes 60 and 67, the frequencies are prominently large. Why 
did such an irregularity in the variation type occur? This might occur by 
chance in such a case as this, where only 80 individuals were observed, but 
it can not be denied that there may be some other complicated causes for 
such an occurrence. For example, if the population of G- P- should consist 
of from more than one pure line, or if the character of the flowering time 
were not fixed and if hereditary variation should to some extent occur, there 
would appear such a variation type as mentioned above. Thus, we were quite 
convinced that unless we raised hybrid progenies together with the progenies 
of their original parents and the hereditary modes of the parent varieties 
themselves are elucidated, we could not reach any exact conclusions. But 
because of careless harvesting of the seeds of the parent plants in the pre- 
vious year, we were not able to distinguish the origin of the offsprings of the 
parent varieties in the present year. 
Besides, we found that I. P. was not an adequate parent variety for the
