Table 15 Class and level to drought resistance of soybean genotypes according to the \( \overline{F_i} \) and SD of MFVD

1

F_i ≥ \( \overline{F_i} \) +  1.64SD

Highly drought tolerant

2

\( \overline{F_i} \)+  1.64SD > F_i ≥ \( \overline{F_i} \) + SD

Drought tolerant

3

\( \overline{F_i} \)+ SD > F_i ≥ \( \overline{F_i} \)- SD,

Moderate drought tolerant

4

\( \overline{F_i} \)- SD > F_i ≥ \( \overline{F_i} \)- 1.64SD

Susceptible

5

F_i < \( \overline{F_i} \)- 1.64SD

Highly susceptible
