[0044] Cross breeding of Lagerstroemiafauriei (Lagerstroemiafauriei) and Lagerstroemia (indicaxfauriei) ‘Tuscarora’)

[0045] (1) Cross-breeding with Lagerstroemia fuchii (♀)×Lagerstroemia speciosa (♂);

[0046] Pest control: From June 15th to 30th, 2012, during the budding period of Lagerstroemia fowleri, the flowering branches of Lagerstroemia fowleri were sprayed with medicine to prevent insects from laying eggs in the buds, and 50ml of methamidophos was used to spray 20kg of water , 2 times a week, 4 sprays in total;

[0047] (2) Flower thinning: On July 5, 2012, each flower branch of Lagerstroemia fowles was retained with the strongest 3-4 branches, the two side flower buds were removed from each branch, and the largest flower bud in the middle was retained, and each flower branch was finally retained twice 10 flower buds that bloom daily, then spray 1000ppm of NAA to the entire flower branch to prevent new branches from sprouting at the cut and form secondary flowering;

Abstract

The invention discloses a crossbreeding method for lagerstroemia fauriei Koehne, and particularly relates to a crossbreeding method for lagerstroemia fauriei Koehne and lagerstroemia (indica x fauriei) 'Tuscarora'. The method comprises the following steps: (1) pest control; (2) flower thinning; (3) bagging, emasculation and pollination; (4) aseptic seedling obtaining; (5) transplantation. By adopting the crossbreeding method for seed selection, the advantages of the lagerstroemia fauriei Koehne and the lagerstroemia (indica x fauriei) 'Tuscarora'; are combined, the stem is brownish red and brown, the panicle is large and beautiful, the flower is red in color, the ripening rate is high, the obtained seeds are full, the filial generation blooms early, and the application prospect is wide.

Description

Technical field [0001] The invention relates to a method for hybrid breeding of plants, in particular to a method for hybrid breeding of Lagerstroemia fowleri and Lagerstroemia safflower, belonging to the technical field of woody plant species selection.
