The invention discloses a taro
sexual reproduction breeding method which comprises the following steps of: 1, taro seed permanent planting; 2, flowering induction, namely performing flowering induction by spraying a chemical on
taro leaves, wherein the composition of the chemical comprise 200-500mg / L
gibberellin; 3,
pollination; 4, seed collection; 5,
seedling raising, namely configuring cover soil, then performing disinfection treatment on the cover soil,
sprouting selected seeds, performing
seedling hardening,
transplanting and performing
seedling-stage management; 6, breeding, namely primarily selecting excellent individual plants with vigorous growth potential and less diseases, marking and
numbering for observation, reselecting according to observation
record information and comprehensive analysis results, performing primary
reproduction and strain
comparative test on the selected individual plants, and breeding the excellent individual plants selected through the strain
comparative test and local adaptability experimental planting, so as to obtain the excellent taro seedlings. According to the method disclosed by the invention, exogenous
hormone is utilized to induce the taro variety to flower, and a
sexual reproduction technology is utilized to
breed a new taro variety, so that conditions are provided for researching taro genetic regularity and breeding excellent new varieties through hybridism.
