Reciprocals. are similar. reciprocals. 



Similar. Dissimilar. Male. Female. 



Maturity period 50% 50% 12% 40% 60% 



Height of plant 30% 70% 15% 35% 65% 



Prolificness 6 % 94 % 27 % 45 % 55 % 



Observations: (i) A great majority of reciprocals are dis- 

 similar. (2) The female parent seems to have a greater influ- 

 ence on the blend in period of maturity, height of plant and pro- 

 lificness. (3) Blends may deviate in a unum even when the 

 parents are similar in that unum ; the deviation is greater the 

 more the reciprocals tend to become dissimilar. 



EXPERIMENT WITH SEEDS REGARDING THEIR POSITION IN THE POD. 



In order to determine the relative quality of peas regarding 

 their position in the pod, ten different varieties were selected for 

 study. From each of the crosses, five pods were selected and 

 from each pod one seed taken from the stem end, one from the 

 middle and one from the tip end of the pod, thus giving five seeds 

 from each position in each variety ; each of which was grown 

 with the following results :
