Abstract : In 1976, the cultivar Alphonso, which is susceptible to spongy tissue formation, was used in a breeding programme as a common parent and crossed with Banganapalli, Neelum, Kalapady and Janardham Pasand, which are free of the ripening disorder. Evaluation of progeny showed that spongy tissue formation is genetically controlled. The character is monogenic and susceptibility to the disorder is recessive, with Alphonso being homozygous recessive. Screening of the hybrid progenies enabled the isolation of 2 promising hybrids: Hybrid 10, characterized by its large fruit size (750 g), and Hybrid 13, more akin to Alphonso in terms of fruit colour, size, quality and flavour. Both are free of the disorder.
