The third purple-anthered F.2 purple tested, 2961-3, gave in F; all the 
color types except dilute purple, Ila, and dilute sun red, [Va. A purple 
plant of the genotype AaBBPIplR’r’ should give the color types 
observed. The observed deviations from expectation might occur by 
chance about once in seven trials, P equaling 0.15. The comparison

A single green-anthered F2 purple, 2960-7, gave four F; color types, 
purple, sun red, brown, and green, all with green anthers. This behavior 
is to be expected from an F; genotype Aa BB Pl pl R’ R’. One of the 
F; purples, 4956-1, repeated this behavior in F,. The F; and F; progenies 
are shown together in the following comparison, for which P = 0.60:

It is of interest to note in this connection that a plant of the genotype 
AaBB Pipl R’ R’ could not exhibit a 27:37 fatio of colored to color- 
less aleurone, as was the case for some of the plants dealt with earlier.
