varieties with good growth, development, adaptability and resistance to pests and diseases, high productivity, fresh feeding and processing contributes to enriching the source of potato varieties We conducted the experiment "Evaluation of some promising potato lines of hybrid combination (2056,2076,2081) in Red River Delta" on hybrid combinations of potato hybrids: 2056, 2076, 2081 and the control variety was Atlantic Morphological, growth, development, yield and resistance to pests and diseases of the hybrid potato combinations were evaluated in the experiment From the results obtained, we selected promising hybrid potato lines from 55 lines, with high individual yield, good growth and development, good resistance to pests and diseases and germination rate Typical highs such as lines 13 and 53 of combination 2056, line 41 of combination 2076, lines 22,58 and 59 of combination 2081 achieved individual yields of respectively 757,8 g / plant, 806,5 g / plant, 987 g / plant, 978,4g / plant, 880,8g / plant,1113,7g / plant From the above results we keep the tubers for the next test to find the best variety for each combination vii PART I INTRODUCTION 1.1 Introduction The Potato (Solanum Tuberosum L.) is the fourth most important food crop after wheat, maize and rice This crop is a staple food and grown as a vegetable for table use, processed into chips, and used for dried products and starch production Potatoes contain important nutrients, even when cooked, that can benefit human health in various ways Nutrients in a potato include vitamin C, protein, fiber, fat, carbohydrate, calcium, potassium, phosphorus, iron, niacin, thiamin, riboflavin Potatoes are grown in 159 countries, the top five potato-producing countries are China, India, Russian, Ukraine and the United States The current potato producing area is more than 19.3 million hectares with a total production of over 368 million tons Potato consumption increased sharply in developing countries Today, potatoes account for more than half of the world's food products, with the advantages of ease of cultivation and high energy content Growing potatoes is a great source of income and brings high economic benefits to many farming households In Vietnam, European potato varieties are quite popular In recent years, the direction of producing processed potatoes in Vietnam began to develop, many potato processing factories of Korea and the United States were built in Vietnam Processing factories required raw materials for year-round demand, which prompted many localities to grow processed potatoes for factories Potato plants have valuable properties such as short growing time, easy to adapt to many climates, many types of soil, economic efficiency and high nutritional value, which are significant in ensuring security food in the world In Vietnam, potato is an ideal crop for winter in the Red River Delta, it does not require the same rigorous seasonality as other crops Growth time is short (90-120 days), but the yield is high On the other hand, potato production has other significant and long-term benefits such as increased yield of subsequent crops, increased fertility and soil fertility, and reduced tillage and weeding costs Currently, the potato variety for processing is Atlantic because it has a high dry matter content and low reducing sugar content However, the growth time of this variety is prolonged (> 100 days), susceptible to late blight, especially the rate of commercial tubers with cracking and emptying of the intestine is high, thus affecting the economy and quality of yield products after processing Therefore, it is necessary to continue to test imported potato varieties to test, evaluate, and select potato varieties with many good properties, adaptable to climatic conditions and meet the requirements of the industrial processing industry From these problems, we implemented the topic: “Evaluation of some promising potato lines of hybrid combination (2056,2076,2081) in Red River Delta” 1.2 Objective and scope of study 1.2.1 Objective - Evaluate growth and development characteristics, agro-biological characteristics, morphological characteristics, pest infestation level, yield, and quality, then select potato lines suitable to weather conditions, agro-soil in the locality, which is capable of resisting unfavorable conditions, has productivity and quality - Proposing potential potato lines for continued growth 1.2.2 Scope of study - Evaluation of some promising potato lines of hybrid combination (2056,2076,2081) in Red River Delta through the assessment of growth, development, and productivity of potato lines of hybrid combination (2056,2076,2081) ACTIVE IMAGE 70 71 72 73 REFERENCES FAO (2020), Potatoes
