What is the top genotype?
Species of walnut seedlings that have undergone genetic mutation are called walnut genotypes. Of these species, seedlings that have the positive traits of a walnut seedling are called superior genotype walnut seedlings. The quality of walnut fruit according to the daily market is one of the most important characteristics of a walnut seedling.
walnut genotype; It has an egg-shaped and coarse structure, and the weight of each walnut with a wooden shell reaches 13 grams. The color of the walnut kernel is light and more than half of the weight of the walnut is specific to the weight of the walnut kernel. This characteristic is representative of the high-quality fruit of the walnut seedling of the superior genotype, which is considered a factor for more sales of this walnut.
What areas of walnut seedlings are suitable for?
Superior genotype walnut; It has good resistance to spring cold and blooms in early May. But it is better to plant in semi-cold or temperate regions because too much cold weakens the performance of this walnut tree. The cold requirement for seedling germination is 700 to 1500 hours.
On the other hand, very high air temperature in summer causes the fruits of this walnut seedling to die. Therefore, regions with not so long winters and mild and cool summers can turn a good seedling into the best walnut seedling. Remember, choosing the right climate brings the maximum performance of the walnut tree.
Canadian walnut seedlings
The quality of walnut seedling fruit is one of the most important characteristics in choosing a walnut seedling for planting. Canadian walnut; It has attracted the attention of the market with its white walnut color and fullness. The weight of each oval and large seed of this walnut has reached more than 13 grams, which is half of the weight of the walnut kernel. The high fat percentage also indicates the properties and pleasant taste of the walnuts of this seedling.
Which Canadian walnut seedlings are appropriate?
Canadian walnut seedlings; It blooms when it has passed the cold requirement of 700 to 1500 hours. For this reason, moderate and relatively cold weather is the best choice for the growth of this seedling. The resistance to frost in spring is also one of the positive points of Canadian walnut seedlings. Of course, in the summer season, the relative warmth of the air helps the growth and flowering of the fruits of this walnut seedling. Excessive heat is beyond the tree's tolerance and damages the products of the walnut garden.
️ Suitable for the clustered walnut seedlings
Before planting walnuts, soil surface, subsoil, ventilation, drainage, soil chemical reaction (PH) and availability of various elements should be tested.
Soil acidity can effectively absorb minerals. Most of the minerals in the range of acidity between 6 and 7 can be absorbed by plants. Usually in cold regions, the chemical reaction of the soil is acidic, and adding lime can increase this chemical reaction.
In addition to Surface soil, subsoil conditions are also important for walnut. Because the roots can penetrate to a depth of 3 meters, the subsoil must be made of rock, hard clay and impermeable layers that limit the roots. The tolerance of walnut trees against hard soil, surface soil and dry soil is better than extreme weather conditions. In addition, complex nematodes and fungal diseases in the soil should be prevented.
انی The walnut seedlings of genotype 7
✅ The later the walnut seedling leaves, the less likely it is to suffer from blight disease, so it can be said that late leafing is considered a quality trait.
✅ The later the flowering date occurs. Damage caused by late cold is reduced.
✅ Male and female flowers are separate in walnut. Usually the male flowers open first and then the female flowers, and this leads to disturbance in the pollination process of the walnut tree. Therefore, the simultaneous ripening of male and female flowers (pollen and pistil) is considered a superior quality.
✅ The shorter the fruit ripening time and the earlier they ripen, the lower the nutritional need and water consumption in walnut. And lateral, if the amount of lateral fruiting is higher, the yield increases and the number of products increases, so trees that have both terminal fruiting and lateral fruiting are known as trees with a superior genotype.
✅ Lower height The tree and its greater extent make the cost of harvesting the product lower, therefore, for the production of the product, a variety that is wider should be planted, walnut trees with vertical growth are suitable for use in the wood industry.
