The hybrid seed produced by crossing
S. melongena genotypes and wild species showed variation in the
germination of F1 seeds and even complete germination failure
was noted in many of the crosses (DBR-G-190 × S. indicum, DBRG-190
× S. integrifolium, DBSR-91 × S. indicum, NDB-25 × S. indicum
and Pusa Kranti × S. indicum).
