Efficiency and applicability of a new method of hybridization
called ‘pollination without emasculation’ was evaluated in
a set of crosses involving Glycine max and Glycine soja
genotypes. The genotypes were crossed in various
combinations to develop MAGIC (multiparent advanced
generation intercross) and NAM (nested association
mapping) population as well as to widen the genetic base
of soybean through wide hybridization. Success of
hybridization ranged from 33 % to 77% during kharif season.
Number of false crossed seeds as measured through
hybridity testing was negligible (0-15%). Rate of crossing
success was more during kharif than rabi (17.33%) season.
The PWE appeared to be highly efficient and applicable
equally to intra-specific and inter-specific crosses in
soybean.
