EXPERIMENT STATION REPORT. 335 



EXPERIMENTS WITH LIMA BEANS. 



The experiments with Lima beans have been chiefly the con- 

 tinuation of the crosses that have been obtained in the "breeder 

 rows" between the "Jackson Wonder" and several white-seeded 

 sorts. 



The "Jackson Wonder" Crosses. 



Selections of five color seed-types were made from the 265 

 plants representing the several "Jackson Wonder" crosses grown 

 in 1906. The number of parent plant in each of the crosses under 

 the several types is shown at the left hand in the following table : 



"Jackson Wonder" 

 Parent Type. Type. 



"Jackson Wonder" Type, ? . . . 132 



Dark Red " 14 



Light Red " 2 



Mottled Red " 12 



White " 20 



180 94 123 44 277 



As might be expected, the "Jackson Wonder" and "white" 

 (that is, parental) types show the least variation, two-thirds of 

 the "Jackson Wonder" and six-sevenths of the white progeny 

 breeding true. From the dark red parentage, one-half of the 

 resulting plants gave seeds with either dark or light red, while 

 one-half reverted to the parents. Results from the light red 

 give three times as many whites as "Jackson Wonder," but, 

 placing the mottled reds with the "Jackson Wonder," the solid 

 colors, 81 in number, are found to be a little over twice those 

 conforming to the parent types. The mottled red gives prac- 

 tically the same numerical results as the "Jackson Wonder" t3^e. 



The plants of the "Jackson Wonder-Burpee" combination were 

 a uniform set, of good bearing quality and with more spreading 

 habit than the "Jackson Wonder" with the earliness of the latter 

 parent. The "blend" of this cross, with a large, dark-red seed,
