VARIATION STUDIES IN BROME GRASS 
19 
Plant No. 25 is an exceedingly abundant stooler. These two plants 
in the past have been practically identical in height growth Plant No 
24 IS a very bright yellow green. Plant No. 25 is a very dark green 
or blue green. Plant No. 24 has very fine leaves and stems, while 
P ant No. 25 is rather coarse. These two plants exhibited about the 
same characteristics in starting in the spring. 
A further contrast is shown in Plate No. 19, between plant No 
24 shown on the left, and plant No. 63 shown on the right. While 
p ant No. 24 is a sparse stooler, it is a vigorous grower, attaining a 
good height and continues vigorous. Plant No. 63 on the other hand ap¬ 
pears to be of very low vigor. It stools very sparsely, starts verv’ ate

in the spring. The progeny rows obtained by planting seed from plant 
^o. 63 have this same slow, sickly development shown by the parent. 
Notes are being taken and studies made to determine if any of 
these various physical characters as exhibited in these original plant¬ 
ings or their progeny are correlated with specific performances. While
