EXPERIMENT STATION REPORT. 481 



Crossing of Squashes. 



In 1903 six kinds of squashes were groAvn as a supplemental 

 crop with the sweet corn, as follows: (i) "Hubbard," (2) 

 "Boston Marrow," (3) "Delicious," (4) "Golden Hubbard," 

 (5) "Mammoth Crookneck" and (6) "Long Island White 

 Scallop." Among the winter varieties, crosses were secured 

 only between (i) "Hubbard" upon (2) "Boston Marrow," 

 expressed by the fraction 1-2. the numerator representing the 

 male and the denominator the female parent; and tlie (3) "De- 

 Hcious" upon (4) "Golden Hubbard," as expressed by the frac- 

 tion 3-4. 



With the bush or summer varieties, full-sized fruits were 

 obtained with both the "Crookneck" and the "Scallop," or flat 

 type as the mother parent, and the crosses are represented by 

 the fraction 5-6 in one instance and 6-5 in the reciprocal. 



A consideration of the differences among the varieties that 

 were crossed is to be found in the report for 1903, pages 479 to 

 482. The fruits resulting from the cross did not differ from 

 others upon the same vines ; in other words, in no instance was 

 there any noticeable effect of the foreign pollen upon the form 

 or other character of the squash. 



During the present season seeds from these crossed fruits 

 have been groun, and one of the remarkable features of the 

 bush plants has been their great vigor. 



Of the winter crosses, only one fruit was obtained the present 

 season, namely, of the "Delicious" upon "Golden Hubbard." 

 and this was pollinated with the "Hubbard" upon "Boston Mar- 

 row," 1-2. The seeds of this fruit, it is presumed, carrv the 

 "blood" of the four varieties above named, and its progeny 

 might be expressed by the compound fraction 1-2 — 3-4. 



The fruit m question is of the "Golden Hubbard" type, and, 

 therefore, resembling the female parent more than ihe male, or 

 "Delicious." It is oval and pointed at both stem and flower 

 eoid, with a prevailing orange color much mixed '\Vith green 

 toward the blossom end. 



One other winter squash was added to the list under experi- 

 mentation, namely, "The Warren," which takes the record num- 

 ber (7), and becomes of special interest, as there is hoj^e that 

 a hybrid may be secured between this and a cross of the bush 

 varieties, which, being upon the latter, is considered in a later 

 paragraph.
