IMPROVEMENTS IN OR RELATING TO HYBRID SEED PRODUCTION

摘要

39 The invention relates to improved methods of hybrid seed production. More particularly it relates to the use of one (or two) phytotoxic chemical resistant genes in the male (and female) parent in a hybridisation process, followed by dosing the resultant hybrids with the one (or two) phytotoxic chemicals to eliminate plants arising from unwanted contaminating seeds and thus produce pure F1 hybrids.
