ABSTRACT
Embryo rescue techniques also have been utilized to obtain progeny from intraspecific hybridizations that do not normally produce viable seed. For example, triploids have been recovered from crosses between diploid and tetraploid members of the same species, and progeny have been obtained from crosses utilizing early-ripening and “seedless,” or stenospermacarpic, fruit genotypes as maternal parents. Embryo rescue techniques have also been used in situations in which embryo abortion is not a concern, such as for overcoming seed dormancy and studying seed development and germination. The various applications of embryo rescue to both applied and basic plant research
have been reviewed by Bridgen (1994), Collins and Grosser (1984), Ramming (1990) and Sharma et al. (1996).
