Embodiment 1

[0028] A comprehensive technology for improving the efficiency of peanut hybridization, comprising the following steps:

[0029] (1) Build a hybridization pool

[0030] The hybrid pool adopts a brick-concrete structure. The bottom of the hybrid pool is made of neutral sandy loam as the lower base, and the upper part is the planting layer. The planting layer is mixed with decomposed farmyard manure and peanut-specific compound fertilizer. 3 Add 6g of 25% wettable powder chlorothalonil and 45g of 5% Duxin granules to the soil for mixing, lay drip irrigation pipes in the middle of the north-south direction to irrigate the planting layer, and finally cover with plastic film. The height of the hybridization pool is 80cm, and the width of the pool is 80cm. The length is 1500cm, the height of the lower base is 40cm, the height of the planting layer is 40cm, and the ratio of N:P:K in the peanut special compound fertilizer is 11:16:18;

Abstract

The invention discloses a comprehensive technology for improving Arachis hypogaea Linn. hybridization efficiency. The comprehensive technology comprises the following steps of: (1) constructing a hybridization pool: adopting a brick-concrete structure for the hybridization pool, taking neutral sandy loam as a lower base layer of the bottom of the hybridization pool, and taking an upper part as a plantation layer; (2) planting a hybridization parent: after hybridization parent Arachis hypogaea Linn. seeds are subjected to coating processing, carrying out plantation processing according to plantation density that two-parent line spacing is 38-42 cm, female parent row spacing is 22-28 cm and male parent row spacing is 13-18 cm; (3) adopting a before-hybridization management technology; (4) carrying out manual emasculation on a female parent; (5) carrying out artificial pollination; and (6) carrying out comprehensive management after pollination: after all combined pollination is finished,before 7:00 every day, manually picking all non-hybrid-pollination flowers on a female parent plant, continuing for 10-15 days, and carrying out proper manual ridging. According to the comprehensivetechnology, which is provided by the invention, for improving Arachis hypogaea Linn. hybridization efficiency, an Arachis hypogaea Linn. hybridization fructification rate can be improved to be about 18% from original 10%, and breeding efficiency is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of peanut hybridization, and in particular relates to a comprehensive technology for improving the efficiency of peanut hybridization. Background technique [0002] Peanut breeding can be divided into introduction, systematic breeding, hybrid breeding, mutation breeding and biotechnology breeding. Among them, hybrid breeding (the so-called hybrid breeding is to use different genotypes of parents to carry out crossbreeding, through genetic recombination, so that the hybrid offspring will have different types of variation, and then through selective breeding, to breed new varieties) is the most common application at home and abroad, and the most outstanding results Methods. The progeny material obtained through artificial hybridization is the most direct and basic source of test material for the research on the selection and breeding of new peanut varieties. Artificial hybridization technology includes selec...
