Germplasm and molecular breeding in horticultural crops

Horticulture is an important part of agricultural planting and production, which is of great significance for enriching human nutrition and beautifying and transforming the human living environment. At present, the area of horticultural crops in China is about 40 million ha, accounting for about onefourth of the national crop planting area, while the production of primary agricultural products is 1 billion tons, and the output value accounts for more than half of the total output value of the planting industry. Traditional cash crops such as fruits, vegetables, melons and tea occupy an important position in the world’s horticultural industry. In addition, the diversity of horticultural germplasm resources in China makes it convenient to exploit the great characteristics of our horticultural crops and cultivated new varieties.
