Rescue of early heart-shaped embryos and plant regeneration of Phaseolus polyanthus Greenm . and Phaseolus vulgaris

In order to improve plant recovery from early heart-shaped Phaseolus embryos, several refinements were made to the embryo rescue technique developed previously in our laboratory. Using P. polyanthus Greenm. and P. vulgaris L. genotypes, a 20% increase in the germination rate was obtained by using Phillips salts and 25 μg.l-1 ABA. This germination medium… CONTINUE READING
