The Inheritance of ‘Dwarf’ Mutants in G. Arboreum Race Indicum

1. The inheritance of four ‘dwarf’ mutants, in indicum was studied.

2. ‘Coimbatore dwarf’ behaves as a monogenic recessive to normal in both arboreum and herbaceum crosses.

3. ‘Anakapalle dwarf’ is a simple recessive to normal while it behaves as complementary to ‘Cocanada dwarf’ Lint colour and plant habit are inherited independent of one another,

4. ‘1767 dwarf’ and ‘Cocanada dwarf’ represent possibly independant mutations at the same locus but carrying different complex of modifiers, and provide an interesting instance of heterosis when intercrossed.

4. The, gene symbols d_a, d_b, are given to Gocanada dwarf and Anakapalle dwarf respectively.
