ON THE INHKRITANCE OF THE FLOWERING TIME IN PEAS AND RICE 
To our regret, no seeds of the V plants which were crosses of the late pure 
line of G- P- li'K-1 been kept. Sown on May 7, sprouting took place evenly 
during the three days from the 17th to the 19th of the same month. The 
frequency distribution of the number of days from sowing to flowering in this 
raising is as shown in Table 8 C- 
Chief Results Obtained from the Above Two Raisings of F; 
1. By summing up the frequencies of every class perpendicularly in every 
group of Table 8 and comparing the sums thus obtained with one another, 
we find in A^; B2 '^'''d C> the minimum frequency classes (page 234) in 
the middle between the variation ranges of the parent varieties, 50 in A^, 
65 in Bo 3.nd 53 in C- I" A2 ^-^tl groups, on account of the small 
number of individuals, it is rather difficult to locate this class, but judg- 
ing from the position of the class in A]^ and Bj, and comparing actual 
number of frequencies in ev^ery class, we may safely fix this class in A., 
at 62, and in B^ at 52. Thus, we see that the values of the minimum 
frequency classes of Aj and A^^ are smaller than those of Bi and Bo. 
That is to say, the minimum frequency class in the variation of the 
families descended from the crosses with the early pure line of G- P- is 
situated earlier than that of the families descended from the crosses 
with the late pure line of G- P. This indicates that the pure line charac- 
ter is hereditary. Now, if we examine again Table 2, we may conclude 
that G- P- II and G- P- V belonged to the same pure line (probably to 
the late flowering pure line), because we do not recognize there any dif- 
ference in the location of the minimum frequency classes among the 
families of II x 13, 16 x II and V x 17, 20 x V. 
2. When we divide all individuals of every family into two groups, the early 
flowering and the late flowering, taking the minimum frequency class as 
the demarkation line, we see that in the early group the white-flowered 
individuals are more numerous than the red-flowered ones, and in the 
late group the number of the white-flowered ones is remarkably small.
