Taking everything into account, the 14 good solutions may be 

 arranged as follows :— First, and best AR2S1, ER3S1, and ER4S1 

 (these being practically alike in physiological worth). Second, AR1S1, 

 AR1S2, BR4S1, BR5S1, CR1S1, CR3S1 and ER5S1 (these being 

 practically alike). Third, FR5S1 Fourth, ER1S1. Fifth, and worst 

 (for the good class), AR3S1 and DR1S1. 



In the poor class the three very poorest solutions (3.4) are shown 



a These solutions show score values of either 1 or 2 by every criterion. They 

 are to be regarded as the best of those having the generalized value 1.6. 



b Solution FR5S1, although graded as 3 by root branching, is graded as 1 by 

 sturdiness of stems, the only case in the entire series where the stems were equal to 

 those of the controls. It must be regarded as a promising solution. 



c Solution EE1S1 has a better grade than solution FE5S1 by leaf condition, 

 but the former is worse by sturdiuess of stems (see table I); otherwise the score 

 values are alike for these two.
