At the lower generation (C5) of the autotetraploid eggplant, plant shape index and the ratio of the well-balanced plants (9.19%) are low. The average shape index for 12 strains of the three different female parents is 0.4779. But its genetic rate is: h^2=96.39%±3.52%. Plant shape index shows strong minus correlation with average fruiting ability, it's relique interrelated coefficient is: r=-0.9989 and correlative heritability is: h=-95.22%.
