crop and heaviest production as compared to hay, sawdust, and bark mulches. 

 With this variety in most sections, the fall crop is the more important.

High Ascorbic Acid Tomatoes. 



A final selection is being made through the cooperation of the North 

 Dakota Experiment Station for a tomato desirable in size, color, and flavor 

 but having double the ascorbic acid content of common varieties. Seed of 

 this should be distributed in 1953.

Carrot Breeding. 



A good flavored, productive, orange carrot similar in shape to Chantenay 

 but more elongated is being sought. The most promising line has come from 

 crosses between Hutchinson and Morse's Bunching.

Sweeter Table Beets. 



Taste panels have been found to prefer sugar beets if they cannot see 

 the white color. From crosses between table beets and sugar beets, strains 

 are being purified which are as sweet as sugar beets while ranking with the 

 good red table beets in color.

Breeding Snap Beans. 



A variety of snap beans which will be white-seeded, green-podded, and 

 stringless is the aim of this project. Several of the selections are being given 

 tests in other locations to determine their possibilities as varieties worthy of 

 introduction.

Chinese Cabbage, Cabbage, and Rutabaga Combined. 



Crosses were made between chinese cabbage, and ordinary cabbage in 

 an attempt to combine plant salad characteristics. Pollen of red cabbage 

 was used, whereas the chinese cabbage served as the mother parent. Some 

 young seedlings from the chinese cabbage seed planted showed red color in 

 their stems and proved to be Fj hybrids. Six of these Fj hybrids observed 

 proved sterile. Stem cuttings from them were rooted in sand and later treated 

 with colchicine. Some seeds were matured on the Fj plants that had been 

 treated with colchicine, and they apparently had a doubled chromosome num- 

 ber. The plants grown from these seeds on flowering, however, also proved 

 sterile. 



The thought occured that the chinese cabbage x cabbage F 1 plants that 

 had a doubled chromosome number were similar in the chromosome number 

 to the rutabaga, which has 36 chromosomes. Crosses were readily obtained, 

 and plants were secured that combined the three species. These plants grew 

 vigorously and when interpollinated set seeds freely, though some individual 

 plants were self-unfruitful. The generation of plants from seeds matured on 

 the three-species hvbrids is being observed in the field during the summer 

 of 1952.
