Embodiment 1

[0015] 1. Screening of high-oleic acid drought-resistant individual plants, using high-oleic acid peanut variety Luhua 11 as the female parent and drought-resistant peanut variety Luhua No. 9 as the male parent, with a hybrid combination, the F1 generation was obtained, and all the seeds of the F1 generation were planted into In the ground, the F2 generation was obtained after selfing; the seeds of the F2 generation were all harvested and planted in the ground, and the F3 generation was obtained after selfing; each individual plant of the F3 generation was harvested 1 full double kernel pod, and the double kernel pod was harvested. 2 seeds are planted in the ground, and after the seeds emerge, a vigorous plant is left, and F4 is obtained after selfing; one full double kernel pod is harvested from each individual plant of the F4 generation, and 2 double kernel pods are harvested. The seeds are planted in the ground, and after the seeds emerge, a vigorously growing plant is left,...

Embodiment 2

[0020] 1. Screening of high-oleic acid drought-resistant individual plants, taking the high-oleic acid peanut variety Huayu 19 as the female parent, and the drought-resistant peanut variety Fuhuan as the male parent, with a hybrid combination, the F1 generation was obtained, and all the seeds of the F1 generation were planted in the ground In this case, the F2 generation was obtained after selfing; the seeds of the F2 generation were all harvested and planted in the ground, and the F3 generation was obtained after selfing; one full double kernel pod was harvested from each individual plant of the F3 generation, and the 2 seeds are planted in the ground, and after the seeds emerge, a vigorous plant is left, and F4 is obtained after selfing; each individual plant of the F4 generation harvests 1 full double kernel pod, and the 2 seeds of the double kernel pod are harvested. Planted in the ground, after the seeds emerged, a vigorous plant was left, and F5 was obtained after self-cr...

Abstract

The invention relates to a high-oleic-acid, drought-resistant and barren-resistant peanut variety breeding method, which comprises the following steps of: 1) screening high-oleic-acid drought-resistant individual plants to obtain high-oleic-acid drought-resistant individual plants; 2) screening high-oleic-acid barren-resistant individual plants to obtain high-oleic-acid barren-resistant individual plants; 3) screening high-oleic-acid, drought-resistant and barren-resistant individual plants to obtain high-oleic-acid, drought-resistant and barren-resistant individual plants, and 4) rapidly breeding the high-oleic-acid, drought-resistant and barren-resistant individual plants obtained at the step 3 to obtain a new high-oleic-acid, drought-resistant and barren-resistant peanut variety. Through the steps, the new high-oleic-acid, drought-resistant and barren-resistant peanut variety can be obtained. The breeding method disclosed by the invention has the advantages of simple process, shortbreeding cycle, small blindness and high efficiency.

Description

technical field [0001] The invention relates to a method for breeding peanut varieties with high oleic acid, drought resistance and barrenness, and belongs to the technical field of peanut breeding. Background technique [0002] Peanut occupies an important position in the agricultural planting structure. As a bulk agricultural product, peanuts are mostly planted on arid and barren hills and mountains that are not suitable for growing food crops. They do not compete with food for land, and they are also good rotation crops for grain and cotton production. Peanut is an irreplaceable high-efficiency crop in some places, especially for areas with underdeveloped agriculture, the economic contribution rate is high, and farmers have a strong willingness to plant it. Because peanuts are resistant to drought and barren, rhizobia can fix nitrogen to improve soil fertility. Therefore, cultivating drought-resistant and barren-resistant peanut varieties plays an important role in incre...
