EXPERIMENT STATION REPORT 265 



of "Canada Crookneck;" with colors from gray to orange. The 

 feature of this cross is the gain in earhness over the "Hubbard" 

 by nearly two weeks; its flesh is intermediate to both parents. 

 ^ Unfortunately, all attempts to obtain a fruit within the cross 

 have failed. 

 ^ "Winter Crookncck-Dclicious" (18/3). The two i)arents are 

 similar to those in the preceding hybrid and the fruits were 

 variable, the great majority of them resembling the "Delicious." 

 Among all were four fruits which were entirely different from 

 either parent, being large, cone-shaped and orange-colored. One 

 fruit was secured by fertilizing within the cross. 



''Winter Crookneck-Faxon" (18/30). This is a third hybrid 

 with the two species represented by the parents blended in shape 

 and color. The vigor of this hybrid was remarkable ; while the 

 vines were slender, its leaves were very large with the leaf stalks 

 long as in summer squashes. The plants developed quite early 

 for a winter squash and remained the latest in the held. But 

 its extraordinary vegetative capacity had developed at the ex- 

 pense of its reproductive function for there were very few male 

 flowers and these had no pollen whatever so that it was impos- 

 sible to attempt fertilizing within the cross. It is to be under- 

 stood that, while its function for perpetuating its kind had failed, 

 fruits were formed quite readily with the pollen from other 

 varieties giving about four fruits to the plant. 



"Japanese-Mammoth Chili" (15/16). This is a union between 

 two species. The "Japanese" fruit is flat and strongly ribbed, 

 while that of the "Mammoth Chili" is large, oval and smooth. 

 The combination of the two gave a medium, pear-shaped, slight- 

 ly ribbed fruit. The two species, however, are so far apart that 

 the blend failed entirely to produce male flowers, but the female 

 flowers fertilized quite readily with some of the other varieties, 

 giving about two fruits to the plant. 



"Japanese-Delicious" (15/3). This is another hybrid between 

 the Japanese species and C. maxima. It also failed to produce 

 male flowers but the female flowers fertilized with other varie- 

 ties, as is seen from the progeny which averaged four fruits to 

 the plant. The fruit has the appearance of the "Japanese" but 

 is much deeper. By reason of the "Delicious" blood contained in 

 It, its table quality is reported to be superior. It is necessary 

 to add that very few good seeds were formed with the fruit. 

 (Plate XXIII). As elsewhere, the only striking difference in 

 the behavior between crosses and hybrids is the weakening of the 

 reproductive function particularly 'to the hindrance of its own 

 perpetuation, but they combine readily with some other kinds.
