Problems solved by technology

However, there are many problems in the production of rapeseed at present: ①The yield is low, and the national average yield per mu is only about 100 kg; Residue and environmental pollution; ⑤ Erucic acid and sulfide in most rapeseeds are high, the quality of edible oil is not high, and the added value of oil meal is low
From the existing known resources, the oil quality of French camelina (C.sativa) is better. The inventor introduced camelina (C.sativa) from France in 1991 and carried out trial planting in Beijing, China, but its stress resistance Poor sex, poor growth, and low yield, with an average harvest of 67 kg of seeds per mu

Embodiment 1

[0018] 1. Interspecific hybridization and immature embryo culture

[0019] The French camelina (C. sativa, hereinafter referred to as Cs) and the wild species of Chinese Inner Mongolia camelina (C. microcarpa f. longistipata, hereinafter referred to as Cm) were selected as parents. Cs leaf entire, short petiole or inconspicuous petiole; parent Cm, leaf edge corrugated notched, petiole slender. Use one of the parents as the female parent and the other parent as the male parent to carry out hybrid combinations, select more than 200 flowers for each combination for artificial pollination, collect fruit balls 15-19 days after hybridization, and soak in 70% alcohol for 10 seconds , then transferred to 1% arsenic-mercury solution, stirred and soaked for 15 minutes, and then rinsed with sterile water 5 times, 5 minutes each time. On the ultra-clean workbench, cut the sterilized fruit balls, take out the immature embryos from the young seeds under a dissecting microscope, inoculate t...

Embodiment 2

[0044] The first strain that obtains with embodiment 1 namely " No. 1 Chinensis " seed, carry out plot cultivation test, plot area is 0.5 mu, repeats twice, sets respectively 20,000 strains / mu, 30,000 strains / mu and The planting density is 40,000 plants / mu; the yields are: the planting density is 20,000 plants / mu, equivalent to 200 kg per mu; the planting density is 30,000 plants / mu, equivalent to 260 kg per mu; the planting density is 40,000 plants / mu Mu, equivalent to 210kg per mu. Field investigation showed no occurrence of pests and diseases.

Embodiment 3

[0046] The seeds of the first strain obtained in Example 1, i.e. "Chinosaurus No. 1", have been carried out field experiments in Beijing and Yi County, Hebei in autumn sowing respectively.

[0047] In Beijing, experiments with different fertilization rates and different sowing densities were carried out. Among them, the treatments of the amount of base fertilizer included: treatment I-application of 20 kg DAP / mu; treatment II-application of 10 kg DAP / mu; treatment III-application of 5 kilograms of diammonium phosphate / mu; assume CK (amount of 0 kg / mu); one mu of land per plot; sowing in early October, when harvesting, the yields are: 196.8 kg / mu, 156. kg / mu, 137.6 kg / mu and 118.4 kg / mu. Sowing density includes three treatments, namely: I-200g / mu; II-100g / mu; III-50g / mu. One mu of land per district. Sowing in the first ten days of October and harvesting, the equivalent yields per mu are: I-139.8Kg / mu; II-121.7Kg / mu; III-103.6Kg / mu.

Abstract

The present invention relates to breeding oil crop through the process of crossbreeding of Camelina sativa and C. macrocarpa f. longistipata as parents; cultivating the hybrid plumule into plant; culturing pollen haploid plant with the anther of the hybrid plant; chromosome doubling to culture amphiploid plant; and multiple generation selection of amphiploid plant seed with thousand grain weight not lower than 1.0 gram to select stable plant for field cultivation. The seed oil of the present invention contains linolic acid over 18 wt%, alpha-linolenic acid over 33 wt%, Camelina sativa acid over 3.05 wt% and vitamin E over 36 mg.

Description

technical field [0001] The invention relates to a method for cultivating plants and its application, in particular to a method for cultivating oil crops by using Camelina genus plants and its application. Background technique [0002] China is a big consumer of edible oil. Vegetable oil has long been in short supply. The annual shortage is more than 2 million tons. Among the domestic edible oils, rapeseed oil has the largest proportion, accounting for more than 50% of the total oil crops. However, there are many problems in the production of rapeseed at present: ①The yield is low, and the national average yield per mu is only about 100 kg; Residues and environmental pollution; ⑤ Erucic acid and sulfides in most rapeseeds are high, the quality of edible oil is not high, and the added value of oil meal is low. [0003] The method for cultivating double-low hybrid rapeseed disclosed in patent document CN1122646A can reduce erucic acid and sulfide in rapeseed, but cannot inc...
