Propagation method of new sunflower number 19 restorer 654 R for oil

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.

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

[0035] (1) Site selection: Select a field that has not planted sunflowers in the past 4 years, and has no self-growing sunflowers; the continuous cropping plots have serious diseases, and there are many self-seedlings, which is not conducive to the propagation of parental seeds.

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

[0037] (3) Sowing: sow every year from June 10th to 25th, and sow late at the appropriate time, which can adjust the flowering period to delay the flowering period appropriately, avoid high temperature or wet and rainy seasons, avoid diseases, and improve pollination Seed setting rate, to achieve the purpose of multiplication and high yield.

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

[0053] By repeating the propagation method of the sunflower Xinkui No. 19 restorer line for oil provided in Example 1, and in conjunction with what the applicant has learned in years of production practice, it is obtained by implementing the propagation method of the oil-use sunflower Xinkui No. 19 restorer line 654R provided by the present application. The following scientific practice results:

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

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