The first-level discipline of the Horticulture consists of four secondary disciplines in the field of pomology, olericulture, tea science and protected horticulture with three recruitment directions respectively.
1. The Pomology
1.1 FruitTree Breeding and Biotechnology
On the basis of collecting and preserving the germplasm resources of apples, grapes, persimmons, apricots, peaches, kiwis, pears and walnuts at home and abroad, this major is to carry out scientific researches on traits genetic regularity and select fruit cultivars in order tobreed new and excellent fruit treecutivas suitable for planting in Northwest China.Moreover, it is oriented to study the fruit tree disease-resistance and stress-tolerancegenetic characters, molecular-breeding, genetic modification and gene editing in purpose of exploiting newdisease-resistantcultivars with independent intellectual property rights in China.
1.2 Fruit Tree Eco-physiology
Targeting to solve the adversity problems in the fruit tree growing areas of the Loess Plateau in Northwest China, this major focuses onthe fruit tree resistance physiology;fruit tree regulation and improvement under adversity conditions such as drought, freezing,strong light, high temperature in summer, low temperature in flowering period, salt stress and soil compaction,etc.Researches on drought-resistance physiology, metabolic regulation andgermplasm resources identification of the fruit trees are highlighted.In addition, researches on key technologies for fruit tree high quality and safety production are carried forward centering on technical issues,including regional layout, cultivar selection and cropping system.
1.3 Post-harvest Physiology & Preservation of Horticultural Products
Focusing onmain fruit varieties of Northwest China, this major mainly carries out researches on fruit (especially apples, grapes, kiwis, permissions and peaches. etc.) post-harvest physiology and preservation,molecular basis for fruit maturation and senescence, as well as fruit post-harvest commercialized processing technology. 
2.  The Olericulture
2.1 Vegetables Genetic Breeding and Biotechnology
This major is oriented to develop excellent vegetable germplasm resources, breed new fine cultivars, exploit and identify important genes and design molecular of important agronomic traits. It also involvesresearches about gene editing; transgenosis; tissue and cell biologyas well as new breeding technologies.
2.2 Olericulture Eco-physiology
This major lays emphasis on application base for vegetable adversity eco-physiology, signal transduction of vegetable hormone path, vegetable organ development biology, vegetable allelopathy, standardized key technology innovation and cultivation technique system for safe and high quality vegetable, establishment of vegetable cultivation technique system, sustainable systemof vegetable field and facilities as well as vegetable growth and development model,etc.
2.3 Vegetable Post-harvest Physiology
This major mainly studies vegetable maturation and senescence physiology and control; post-harvestmolecular biology and commercialized processas well as storage and preservation technologies of vegetable products.
3. Tea Science
3.1Tea Tree Breeding & Biotechnology
Students in this major are designed to collect tea tree cultivars all over Shaanxi Province, introduce other representative cultivas around China, set up tea germplasm resources nursery and breed newcultivars with both biotechnology and traditional breeding methods.
3.2 Tea Tree Eco-physiology
This major is to carry out researches on secondary metabolism of tea tree and regulatory enzymes inthe metabolite formation and transformation paths; develop tea bio-active components; study the pharmacological functions of tea featured components, exploit tea-based natural resources, as well as to expand tea application in other fields.
3.3 TeaProcess Engineering
This major is to learn tea quality development rules during the preliminary and deep process in order to design tea processing technique,innovate new processing facilities and exploit novel tea products. 
4.  Protected Horticulture 
4.1Horticultural Facility Engineering
This major concentrates on research and development of new materials for facility engineering, efficient application of new renewable energy in agriculture, new technology for energy saving and emission reduction. Researches also involve facility structure innovation and performance; regional planning of horticultural facilities; as well as agricultural construction engineering technology, etc.
4.2 Protected Horticulture Environment Engineering 
This major mainly conducts researches on simulation model of environmental factors including temperature, light, water, fertilizer and air, as well as intelligent and automatic controlling technology. It also studies interaction mechanism between protected environment and horticultural plants.
4.3  Protected Horticulture Eco-physiology 
The dominating research fields for this major include protected horticultural plant eco-physiology; interaction effect between environment and plant growth; new cultivation patterns for protected horticultural plants; growth model of green-house plants; stress physiology of protected horticultural plants as well as their molecular biological mechanism.
