A STUDY OF EARLINESS AND LATENESS. 



The Biometric curve constructed on Early and Late groups 

 (Fig. 3) shows that in period of maturity: 



1. The greatest frequency distribution in blends between an 

 early and a late parent resembles the early parent, or in other 

 words, when an early variety is crossed with a late variety, the 

 offspring stands the greatest chance of being like the early parent. 



2. Of the blends intermediate to the two parents, the greater 

 frequency distribution is more toward the early parent, that is, 

 when an offspring from an early and late parent, is intermediate, 

 it stands the greater chance of resembling the early parent more 

 than the late parent. 



3. There is an aggravation on either side but more in num- 

 ber and degree on the early side ; in other words, blends may be 

 earlier than the early parent, or later than the late parent but the 

 former chance is greater. 



Conclusion : Li the blend generation, earliness is a stronger 

 character than lateness. 



A STUDY OF SIZES OF PLANTS. 



The Biometric curve constructed on Short and Tall groups 

 (Fig. 4) shows that in height: 



1. The greatest frequency distribution in blends between 

 parents of different heights is intermediate to the parents; in 

 other words, when a short plant is crossed with a tall plant, the 

 offspring stands the greatest chance to be intermediate in height 

 to both parents. 



2. Of the blends resembling the parents, the greatest fre- 

 quency distribution is like the tall parent, that is, there is a much 

 greater chance for the oft'spring to be like its tall parent than its 

 short parent. 



3. There is an aggravation on either side but more in number 

 on the tall side, or in other words, blends may be taller than the 

 tall plant or shorter than the short parent but the former chance 

 is greater. 



Conclusion: Plants in the blend generation have the greatest 

 tendency to be intermediate to both parents, and a strong ten- 

 dency to be like the tall parent.
