How to select high-quality rapeseed varieties

The selection method of rape varieties is as follows:

1. Understand the characteristics of varieties and select high-quality rape varieties.

According to different breeding methods, rape varieties are customarily divided into conventional rape and hybrid rape. Because of the existence of hybrid rape

The yield is relatively high, but the price of seeds is relatively expensive because of the difficulty in seed production. In recent years, there are many varieties of hybrid rapeseed popularized and applied in our province, mainly including Xiangzayou series, Fengyou series, Huaxiangyou series, Zhongzayou series and Huaza series. Common conventional rape varieties are Zhongshuang No.9, Zhongshuang 1 1, You Xiang 17, etc.

According to the quality characteristics of rapeseed varieties, it can be divided into two categories: high-quality rapeseed and ordinary rapeseed. According to the industry standard of low erucic acid and low glucosinolate rape seeds issued by the Ministry of Agriculture, the erucic acid content of high-quality hybrid rape seeds should not exceed 2.00%, and the average glucosinolate content of parents should not exceed 30.00? Mol/g cake, F2 glucosinolate content shall not exceed 40.00? Molar/gram cake. The erucic acid content and glucosinolate content of high-quality conventional rapeseed varieties should not exceed 1.00% and 30.00? Molar/gram cake. High-quality rape not only has good quality of rapeseed oil, but also its cake can be directly used as feed and its vegetable moss can be used as vegetables. Its direct economic benefit and comprehensive benefit are obviously higher than that of ordinary rape.

2. Choose locally grown rape varieties with good performance.

Different climate, soil and cultivation habits will produce great differences in crop varieties. Therefore, when selecting varieties, we should choose the main varieties that have been tested and demonstrated by the local agricultural authorities and performed well, especially those that have performed well in the local high-yield creation.

3. Choose suitable varieties according to the farming system and sowing method.

Transplanting rape or rice-oil double-season transplanting rape should choose varieties with fertilizer tolerance, sparse planting tolerance, tall plant type, great yield potential per plant and good lodging resistance, such as Huayouza series and Zhongyouza series. Winter and semi-winter medium-late maturity rapeseed varieties should be selected for autumn hair cultivation.

4. Other problems that should be paid attention to when selecting varieties:

① Look at the output data in advertisements rationally.

(2) Go to the local agricultural technology station or the regular seed sales department to buy seeds. Do not buy seeds with unknown sources.

(3) Obtain and properly keep the seed purchase invoice, which can be used as the basis for claim when there is a problem with the seed quality.

(4) Pay attention to the contents marked on the seed package to ensure that the required qualified seeds can be bought.
