EXPERIMENT STATION REPORT. 45P' 



])ortion of the seed is a plain black. This peculiar disposition of 

 c(i](ir is to be made out by a close inspection of the engraving, but,, 

 ill reality, it is very evident, giving the seeds a striking charac- 

 teristic. At 20 the seeds are quite sugge'stive of the female parent 

 (21) because the light tan color, confined to the "eye" in the latter^ 

 is here spread over nearly onedialf of the seed, as is (piite ])lainly 

 shdwn in the engraving. 



In the fourth row the two parents are "Crystal Wax" (145) and 

 "IJrirtle Wax" (101), the former being the male, and is a variety 

 with a small pbmt and Avhito flowers, producing short, round,, 

 curved pods, thick in flesh and bearing very small, oval, white seeds 

 late in the season. The "Brittle Wax" is a medium-sized plants 

 fairly early in bearing, with white flowers, long, round pods, and 

 medium large, long, often cui-ved, seeds with a dark "eye." 



Points of contrast are many between these two varieties, not the 

 least being the color of the pods which is a pea-green in the 

 "Crystal," due to the chlerophyll being located largely in a layer 

 at a distance from the surface of the pod, while the ''Brittle" is of 

 the true wax type. 



At 23 is shown the seeds of the third generation of a white- 

 seeded strain of the cross. It is much more productive and some- 

 what earlier than the "Crystal," and the seeds, a decided oval, are 

 somewhat larger than the latter. The seeds at 24 appear nearly 

 black but are a dark, mottled brown and quite near in this respect 

 to tlie blend obtained from the original cross. At 25 is shown a set 

 of seeds in its second generation which are remarkably long and 

 curv-ed, medium between the two parents in size and with a dark 

 "eye" that considerably exceeds the "Brittle." The seeds at 26^ 

 are still smaller and decidedly curved, with a dark color at the 

 "eye" that is usually only a portion of a circle. This shape of 

 seed seems to be correlated with a round, plumpi pod much sought 

 for. The seeds at 27 are pure white and of a sha|3e that agrees 

 quite closely with the "Brittle" (28) near which they are placed. 



A: study of the combinations of characteristics that do not per- 

 tain to the seeds shows some points of interest in the breeding of 

 these plants. ,
