EXPERIMENT STATION REPORT 237 



"Jackson Wonder" and "dark red" j^-roups, the total averages in 

 their tabular order being 37.5, ^t,.^ and 39.4, respectively. Two 

 thousand and three hundred and seventy-six plants of this set 

 were grown the past season and a reference to the table will 

 show the degree of conformity to type in respect to color inherit- 

 ance. 



The evidence given above is not sufficient to warrant the state- 

 ment that the two seed colors, ''Jackson Wonder" and "dark 

 red," are always associated with the most prolific plants but it 

 does seem safe to conclude that both the "Jackson Wonder" and 

 "white" strains are being established through selection and. isola- 

 tion. 



"jACKSON WONDER-DREEr" CROSS. 



The "Dreer" is a variety of the "Potato Lima" type, possess- 

 ing a distinct foliage in its long, slender, light green leaves 

 together with the characteristic short thick pods, containing 

 round, meaty, greenish white seeds. These several distinguish- 

 ing traits, taken from the standpoint of breeding, make this 

 cross the most interesting, if not the most important, of the 

 "Jackson Wonder" set 



Since the "Jackson Wonder" has a dark green foliage with 

 shorter and broader leaves than the "Dreer," the progeny, as 

 might be expected, gave plants which, in their leaf character, 

 may be classed in three groups, one for each parent type and a 

 thh-d termed "intermediate" for the reason that the plants of 

 this class, in respect to foliage, are a medium between the other 

 two. 



Such a classification was made in the case of one hundred 

 and seventy-two plants of this cross and sixty- four were included 

 in the "Jackson Wonder" group, seventy-four in the "inter- 

 mediate" and thirty-four were classed as having "Dreer" 

 foliage. 



Plants grown this season were from seeds of a "Jackson 

 Wonder," "dark red" and "white" types, representing two hun- 

 dred and ninety-one plants. The choicest of these, those from 

 white seed, were grown on the "Strip Land" and gave but one 

 plant with colored seeds (dark red). 



About half of the white-seeded plants bore a close resemblance 

 to "Dreer" in general habit of growth and type of pod, while 

 less than half gave the plump, round seed possessed by that 

 parent. The strong running tendency, noted last year, which 

 was also a trait of the "blend" plant, dominated this season's 

 growth as well, there being two hundred and fiftv plants with
