Every winter until the winter, seedlings ads fly. For grapes, there are more than 160 nucleated cultivars and more than 30 nucleus-free cultivars. The quality of various seedlings is uneven, and authenticity is hard to distinguish. So how can we introduce high quality grape seedlings? The author thinks to look at the following aspects.

A look at the planting area and economic conditions Each species has its own regional adaptability, and it is necessary to cultivate in an appropriate manner.

Second, to see those who have mastered the technology proficiency in better cultivation techniques, they can choose high-end varieties with high market prices and high cultivation difficulties; those who have not yet mastered cultivation techniques should choose manageable varieties and introduce a few high-grade varieties at the same time.

Third, look at the market positioning If you are selling to big cities and supermarkets, you should choose high-quality varieties that are good in quality, resistant to storage and transportation, and you also need to have a certain scale of planting; if you sell at a nearby or rural market, you should choose high yield and manageability. Large varieties. In addition, according to the market's consumption habits, select strawberry flavor or rose flavor, rock sugar or sweet and sweet varieties.

Fourth, to look at the source of the variety, it is necessary to figure out which species the selected species is, where the origin is, whether it is hybrid or budding.

5. Look at botanical characteristics Each species has its own special botanical characteristics, and a variety can be identified and judged based on the botanical characteristics of the species. In general, the appearance of large populations varies greatly, while the difference in the appearance of the same population is small.

Sixth, when you look at biological characteristics to select varieties, you must understand its growth potential, disease resistance, high yield and budding, flowering, maturing and other biological characteristics.

When looking at fruit trait selection varieties, it is necessary to understand the average ear weight, grain weight, fruit setting rate, soft or brittle flesh, whether it is easy to color, whether it cracks fruit, threshing, whether it is resistant to storage and transportation and other fruit traits. Many varieties have only one drawback, and even if other comprehensive traits are good, they will limit their development.

Seeing that the seedlings and nursery units must go to the formal seedling production units to purchase seedlings to understand whether the seedlings for the seedlings have been registered and issued by the relevant departments, whether the business license, the seedlings business license, the seedlings quarantine certificate are complete, whether there is a nursery, and how large the scale is. Whether the seedling purity can be guaranteed and so on.

Nine to see whether seedlings grafted seedling grafted seedlings generally use high resistance rootstock. The resistance requires cold resistance and disease resistance.

10 See if there is a successful result. When selecting a variety, it is best to choose a variety that has been successfully cultivated. Each species has its own unique traits, and good methods can improve the economic benefits. Only by understanding the characteristics of breeds, and then avoiding weaknesses, can we obtain good economic benefits.
