METHOD FOR PREPARING HYBRID SEED USING CONVENTIONAL FEMALE STERILITY

摘要

FIELD: genetic engineering, genetics, agriculture. SUBSTANCE: plant with conventional female sterility is prepared using transformation of chimeric construction comprising promoter preferable for female reproductive system and sequence encoding enzyme catalyzing the conversion of protoxin to toxin. The following compact planting plants with conventional female sterility and plants with male sterility and induction of female sterility by treatment with protoxin results to preparing highly heterosis hybrid seeds. Invention can be used for preparing hybrid seed material of plants. EFFECT: improved preparing method. 28 cl, 2 dwg, 16 ex
