Breeding for Quality and Productivity in Anthuriums . To 

 (l) improve quality in color, form, texture, size, and glossiness 

 of the flowers; and (2) increase productivity of plants. 



Hort. 177.1 



Breeding Hardy Ornamental Trees and Shrubs for Minnesota . 



(1) Develop through breeding: hardy varieties of small to 

 medium sized trees for landscape purposes that combine hardiness 

 with other desirable characteristics as showy bloom, good texture, 

 attractive fruits, good autumn color, and winter interest; (2) 

 hardy varieties of dwarf compact shrubs possessing characteristics 

 as above.

Improvgnent of Ornamental Plants . To (l) survey characters 

 of selected species and horticultural varieties of ornamentals, 



(2) study inheritance of these characters, (3) produce through 

 breeding and selection new varieties superior in vigor, disease 

 resistance, beauty and adaptability, and (4) improve cultural 

 methods • 



Hort. 38 



Cytogenetic Studies of Horticultural and Crop Plants . To 

 apply fundamental principles of cytology and genetics to develop- 

 ment of new and improved varieties of horticultural and crop 

 plants such as com, iris, rye, cantaloupes and Cattleya orchids 

 and to eliminate defects of certain varieties such as partial 

 sterility which are cjrtological in nature.

The Breeding and Improvement of Ornamental Shrubs of the 

 Caprifoliaceae . To develop improved varieties of the Caprifoliaceae. 

 including such characters as dwarf to medixim height; upright, 

 spreading, evergreen growth; attractive types of inflorescences; 

 consistency of fruiting, large size, etc.; cold tolerance; and 

 disease and insect resistance and tolerance.

Develop. Procure, Propagate, and Test Dwarf. Woody Ornamental 

 Plants ! To (1) use certain ornamentals now at VPI Arboretum and 

 produce dwarf types from other sources; (2) develop new forms through 

 hybridization, selection and use of X-ray, chemical, etc. to induce 

 gene mutations; (3) study methods of . propagating dwarf plants and 

 response to different chemical fertilizers; and (/♦) test dwarf 

 ornamentals in various soils and exposures for hardiness, rate of 

 growth and resistance to pests.
