Example Embodiment

[0034] Example 1: Breeding of restorer line 654R of oil sunflower Xinkui 19

[0035] (1) Site selection: select fields that have not planted sunflowers or self-grown sunflowers in the past 4 years; continuous cropping plots are more diseased and have more seedlings, which is not conducive to the expansion of parental seeds.

[0036] (2) Seed treatment: dress the seeds of Xinkui No. 19 restoration line 654R with chemicals to prevent underground pests such as cutworms and ensure the emergence rate.

[0037] (3) Sowing: sowing from June 10th to 25th every year, and sowing late at an appropriate time. The flowering period can be adjusted so that the flowering period can be postponed appropriately, so as to avoid high temperature, humid, and rainy seasons to avoid disease and improve pollination. The seed setting rate achieves the goal of multiplication and high yield.

[0038] (4) Seedling stage: When the seedlings grow 1-2 pairs of true leaves, according to the typical characteristics of...

[0052] Example 2: Verification effect of breeding method of oil sunflower Xinkui 19 restorer line 654R

[0053] By repeating the method for breeding oil sunflower Xinkui No. 19 restorer line provided in Example 1, and combining with the applicant’s years of production practice, it was obtained by implementing the breeding method of oil sunflower Xinkui No. 19 restorer line 654R provided in this application The following scientific practice results:

[0054] The net shed is 2.5m high, 2000m long, and 9m wide, which is conducive to tractor farming. The net frame is made of steel structure, and the steel frame must be stabilized to avoid strong winds. The nylon mesh cover must be 80 mesh gauze. The 60 mesh mesh is too large to meet the isolation requirements, which will affect the purity of the restoration system seeds; the 100 mesh gauze net is too dense, and the restoration system in the mesh cover has poor ventilation and light conditions. The growth of the restoration system has ...

[0057] Example 3: The verification effect of the breeding method of the oil sunflower Xinkui 19 restorer line 654R

[0058] For many years, through the use of the present invention in Xinjiang Agricultural 12th Division and other places to provide oil sunflower Xinkui No. 19 restorer line 654R propagation method, 5 acres of 654R are isolated in a net shed, and artificial powder puff is used for pollination. After harvesting and testing, it is found that its yield per mu is obvious Higher than bagging artificial pollination and breeding, and the labor cost is less than half of bagging breeding. Through identification of its restorer line in Hainan: the purity of the parent is 100%. It shows that the breeding method of the oil sunflower Xinkui No. 19 654R provided by the present invention is irreplaceable in terms of increasing yield, saving cost and improving purity.

Abstract

The invention discloses a propagation method of a new sunflower number 19 restorer 654 R for oil. A nylon oil net house is isolated on a selected propagation field through isolation of a protective screen. The net house requires that the height is 2.5m, the length is 2000m, and the width is 9m. The net house is made of steel. A steel frame needs to be stably built and prevented from being blown down. A screen with 800 meshes is selected and used to manufacture a nylon net. Doors are reserved at two ends of the net cover for people to enter and sewed by using an about two-meter plastic zipper. People can conveniently go in and out. The problems of parent strain purity, yield and cost are solved through the method of net house isolation. Not only the purity is ensured, but also propagation yield is improved. Besides, the propagation method of the new sunflower number 19 restorer 654 R for the oil is low in cost and has an important application value.

Description

field of invention [0001] The invention relates to the technical field of plant propagation, in particular to the technical field of propagation of a sunflower restorer line for oil. Background technique [0002] Sunflower (Helianthus annuus L.) is one of the five major economic crops in the world. It is resistant to salinity, drought, and barrenness. It is also the main oil crop in northern my country. It is increasingly valued as an oil or protein resource. There are quite a few dry and barren low-yield fields and saline-alkali land in China, so sunflower plays an important role in agricultural production. All countries in the world have generally carried out three-line research on the utilization of sunflower heterophylls. my country has carried out research on the utilization of sunflower heterozygous species since the 1970s, and began to use hybrids in agricultural production. [0003] Oil sunflower Xinkui No. 19, formerly known as Kangdi 1064, is a mid-to-late-maturin...
