UMaine ໄດ້ຮັບທຶນເພື່ອຄົ້ນຄວ້າມັນຕົ້ນທີ່ທົນທານຕໍ່ຄວາມຮ້ອນ

The University of Maine has received $510,104 in federal funding to conduct research on potato breeding in Maine to make the crop more heat-tolerant and resistant to pests. The funding was awarded through the U.S. Department of Agriculture’s National Institute of Food and Agriculture, said U.S. Sens. Susan Collins, R-Maine, and Angus King, I-Maine. “Maine’s potato industry is an integral part of our state’s heritage and plays a major role in our state’s economy,” Collins and King said in a joint statement. “Although the crop was hit hard last year by the pandemic and drought, Maine’s potato farmers have proven their resiliency time and time again.” The federal funding will support research at the university to develop new potato varieties with improved heat tolerance and increased resistance to pests and disease, as well as improve information-sharing and collaboration with stakeholders. “By investing in UMaine research to improve the potato’s resistance to extreme weather and other stressors, this funding will support Maine farmers’ efforts to protect their crops and ensure that this industry remains strong for generations to come,” Collins and King said. Last year a drought, combined with COVID-related drops in the potato markets, resulted in the 2020 crop being...

Currently, virologists count from 27 to 33 types of viral diseases of the potato. Under natural conditions, viruses can spread when a diseased plant comes into contact with a healthy one or through the soil (nematodes or zoospores of chytrid fungi), viruses can be carried by insects (aphids or leafhoppers).The primary infection, affecting plants, creates conditions for the infection of tubers and the development of a secondary, more severe infection of the next vegetative generation, as the concentration of the virus increases. Some viruses can be transmitted by real potato seeds or even pollen, but their concentration is negligible.Potato viral diseases have caused huge crop losses for at least 200 years, and only in the last 40-50 years have their pathogens been identified and characterized. One of the most harmful viruses in potatoes are viruses X and Y: yield losses reach 50-80%, sometimes more, depending on the contamination of the planting material and growing conditions.

The CIP Genebank initiated in vitro cultures more than 40 years ago and has extensive expertise in developing and assaying tissue culture technologies for these crops. In vitro cultures are initiated from and maintained sterily as identical replicates (clones of plantlets) of the original mother plant. They are routinely transferred to maintain optimal viability and to ensure that phytosanitary clean germplasm is available for immediate distribution and use. These in vitro accessions are the primary source of germplasm for characterization, genetic identity, DNA extractions, pathogen elimination, cryopreservation, safety back-up, and distribution to breeders, farmers, and researchers within CIP and worldwide. The in vitro conservation methods developed by CIP’s genebank use treatments for reducing plantlet growth, such as osmotic stress and low temperature for storage to keep viable plantlets in a medium-term-storage (MTS) period where transferring is not needed as often. CIP’s potato method is quite efficient, by using low temperature (6-8°C) and culture medium containing sorbitol as an osmotic agent, the need for fresh transferring is prolonged from once every 6-8 weeks to two years. This is currently the most robust method for conserving potato collections and is used by most potato genebanks worldwide. A similar method is applied to the other tuber crops; however, the germplasm may not...

Throughout 2021, as part of Potato Grower’s celebration of our 50th year in publication, we will be honoring in our pages and on our website 50 of the potato industry’s most innovative and influential individuals, companies and organizations over the past half-century. This “50 for 50” series will include researchers, salesmen, packers, processors and, of course, plenty of potato growers. A lot of them will be names you’ve heard before. To some, you’ll get a fresh introduction. Regardless, each has had an outsize impact on the U.S. potato industry, and each deserves our thanks and recognition. To view the full roster of “50 for 50” honorees, click here.  At the height of World War II, demand for agricultural commodities increased dramatically. American farmers—including potato growers—responded brilliantly, ramping up production to unprecedented levels. However, when the war ended, demand sharply decreased, and this depressed market conditions for, among other things, potatoes. At the time, potato production was expanding across the country, but no framework existed on a national level to facilitate the movement of surplus potatoes. In 1948, a group of growers with incredible foresight formed the National Potato Council (NPC) to promote potato consumption and nationally represent the nation’s then-45,000 potato growers on legislative...

Potato is an essential crop for food, culture and the economies of Andean countries and the world. Although there is little documentation of the exact route of introduction of potatoes to Europe, it is believed that potatoes were first introduced in the region of Seville, Spain, as there are hospital records showing acquisition of potatoes in 1573 (Hawkes 1990). It is assumed that from the introduction in Spain, potatoes were transported by different routes and subsequently adapted to other continents (Africa, Asia, and Australia) as a staple crop. The cultivated potato is native to South America, and its centers of origin and diversity are located in the Andes mountain. The Collao plateau, the watershed basin of Titicaca Lake, with the corresponding territories of Peru and Bolivia are believed to be potato’s primary center of origin and diversity. Other secondary centers of diversity are southern Bolivia, northern Argentina, Pasco’s Knot Peru, Loja’s knot, Ecuador and Peru; volcanic complex of Chimborazo, Tungurahua, Cotopaxi in Ecuador and the nude asture in Colombia. These geographic areas were involved in the interaction of potato cultivation with early human cultures, a reliance that extends to the present day in many Andean indigenous communities . The geographical...

In the absence of harmony between the biology of the variety and the environment, the physiological functions of the body are disrupted, which leads to a weakening of its viability, depression and, finally, to a significant decrease in the productivity and quality of planting material. Therefore, for seed production of each variety, the optimal growing zones and certain dates for the variety renewal of the planting material must be selected. The availability of good varieties is not enough for successful potato growing. A prerequisite at all stages of growing seed material is strict adherence to the requirements of potato seed production, which should ensure for a long time not only the preservation, but also the improvement of the valuable qualities of the variety. Insufficient attention to seed production leads to such dire consequences as the spread of various diseases on potato plants, a rapid decline in yield, and the release of the variety into circulation. One of the main tasks in potato seed production is the fight against viral diseases. Their widespread occurrence on potato plantations is most often the main reason for the poor quality of seed material. Therefore, growing seed potatoes free from viral infection is a key...

Studies in three Africa countries validate the value of seed system tools  Cassava trader in Uganda Seed systems are essential for getting new crop varieties to farmers and, in the case of banana, cassava, potato, sweetpotato and yam, they can improve the yields of established varieties. This is because farmers plant vegetatively propagated seed (e.g., tubers, vines, or roots) for those crops, and that planting material is frequently infected with pests or diseases that can significantly reduce yields. This constitutes a persistent threat to the incomes and food security of the hundreds of millions of smallholder farmers in Africa, Asia and Latin America who depend on root, tuber and banana (RT&B) crops for nourishment and livelihoods. Recent research in three African countries using tools developed to better understand and improve farmer access to and use of improved varieties and quality seed points the way toward holistic solutions to the dilemma of diseases and pests spread by seed, and opportunities to improve production of RT&B crops by resource-poor farming families. Teams of young men and women researchers and development professionals who work with RT&B crops undertook research on characterizing seed systems and diagnosing bottlenecks in Ethiopia, Tanzania and Uganda in recent months and presented their findings in a three-day virtual workshop in late...

In production conditions, the variety is gradually deteriorating. To maintain all its valuable biological properties at a high level at all stages of seed production, special seed methods and measures are used: selection of typical healthy plants in the primary links of seed production in the production of elite seeds; growing plants in optimal agrotechnical conditions that contribute to the formation of high-yielding tubers; prevention of damage to plantings and tubers by diseases and pests; carrying out varietal and phytopathological cleanings; allocation of the most complete fractions for planting.The seed material obtained under such conditions provides an increase in yield in commercial plantings by 20-30%. That is why it is so important every year to provide on seed plantations a complex of agrotechnical, phytosanitary and organizational measures aimed at obtaining planting material with high yielding qualities. The varietal qualities of tubers depend on the genotype of the seed itself, that is, if the seeds belong to a high-yielding variety, then they potentially make it possible to grow a high yield, and if to a low-productive one, then even when planting a high-yielding seed material, a high yield cannot be obtained. The yielding properties of seeds mean the ability of different...
