42 Department of Plant-Breeding. 



Courses. The following courses were offered to graduate and under- 

 graduate students : 



Graduate courses. — Research (5). Problems in plant-breeding, hered- 

 ity, and general evolutionary topics. 



Seminar (6). A seminar for the discussion of fundamental problems 

 of plant-breeding, heredity, and general evolution, methods of breeding, 

 etc. 



Undergraduate courses. — Plant-breeding ( i ) . This course will under- 

 take a careful consideration of the principles and practice of plant-breed- 

 ing with reference to variation, selection, and hybridization, as factors 

 in the amelioration of cultivated plants. Special consideration will be 

 given to the methods and results of present-day plant-breeders. 



Advanced plant-breeding (2). A critical study of the principles under- 

 lying breeding: variation, transmission and fixation of characters, corre- 

 lation, biometry ; theories of the mechanism of heredity. 



Beside teaching the above courses this division has cooperated with 

 the Department of Plant Pathology and the Division of Pomology of the 

 Department of Horticulture, by giving some lectures and demonstrations 

 on topics of mutual interest. 



Equipment. — This division has no classroom, laboratory, nor green- 

 house of its own and was forced to use those of other departments. 

 Necessary apparatus is being purchased gradually, as funds will allow. 



investigation. 

 All of the investigations of this division are being done in conjunction 

 with the experimental division (see report of Experimental Division). 



extension. 

 This work may be grouped as follows : 



1. Correspondence. — The correspondence, which is increasing yearly in 

 amount, is carried on in conjunction with the experimental division. Not 

 a little time is spent in answering questions from farmers in this and 

 other States and in giving directions on methods of breeding plants. 



2. Lectures. — Many lectures have been given to farmers' organizations 

 of various kinds throughout the year. The only limit to the number 

 has been the lack of time on the part of the instructors because of duties 

 in the classroom and laboratory. Practical talks at agricultural fairs 

 have also been given. 



3. Winter Course. — No regular winter-course work has yet been 

 scheduled for this department. Several talks have been given, however, 

 to winter-course students m conjunction with the other classes.
