Dr. Small announced that the Field Schedule would be in the 

 mails within a short time. 



The scientific program of the evening was presented by Dr. 

 D. F. Jones of the Connecticut Agricultural Experiment Station. 

 Dr. Jones gave an illustrated talk on the "Chromosome Relocation 

 and Degeneration in Relation to Growth and Hybrid Vigor." The 

 speaker's abstract follows : 



The inherited characters studied by geneticists for the most part have 

 been highly selected to show clear-cut segregation with complete or nearly 

 complete dominance and recessiveness. Small changes in growth rate or 

 physiological efficiency are not easily detected and have been generally 

 overlooked but these play an important part in heterosis and give informa- 

 tion concerning growth and development. Spontaneous growth changes are 

 rarely found in maize endosperm but are easily identified and related to 

 chromosomal changes. Some of these give indication that critical regions 

 in the chromosomes are involved. 



The meeting was adjourned at 9.45 p.m. 



Respectfully submitted,
