PLANT Coors In MAIzE 89 
In conclusien it seems safe to say that the cross of green-anthered 
purple, Ig, with green of type VIc, has given results similar to those 
yielded by the cross of brown, V, with green of type IVg. Since this 
was to have been expected from the hypothesis suggested by the F. 
generation of the latter cross, the results just discussed lend support to 
that hypothesis. 
Purple Ig x dilute sun red TVa—JIn accordance with the hypothesis 
under consideration, green-anthered purple is A B Pl R’ and dilute sun 
red is Abplr’. F, of the cross should be A A Bb Pl pl R’ 7’, and Fe 
should consist of the five major color types, purple, sun red, dilute purple, 
dilute sun red, and green of types IIIg and IVg, with both green-anthered 
and colored-anthered subclasses of purples and sun reds. The I; plants 
were purple-anthered purples, as expected. Three F: progenies are 
recorded in table 38, group 1. Anther color could not -be recorded in 
all cases, but in each of the three F. progenies both green and colored 
anthers were noted for both purple and sun red plants. In one progeny, 
5042-5045, of a total of 57 purples and sun reds, 41 had colored and 16 
had green anthers, which is not far from the expected 3:1 relation. The 
415 F, plants were so distributed among the five color classes that the 
chances are nearly three in five that the deviations observed may have 
been due to errors of random sampling, P equaling 0.58. A comparison of 
observed and theoretical distributions follows:

An F, of the cross here considered, 6557-12, A A Bb Pl pl R’ 7’, was 
backcrossed to a dilute sun red, Ab plr’. Four color types occurred in 
the progeny, as expected, and all the plants had colored anthers. The 
deviations from expectation were suchas might occur by chancein consider- 
ably more than one out of any two such trials, P equaling 0.56. The 
comparison follows:
