A new era for potato breeding: Unraveling genetic complexity, opening the door to more efficient potato breeding

PhD candidate Corentin Clot of Wageningen University & Research has made significant discoveries related to potato sexual reproduction that could simplify the breeding of this important crop. Clot’s research focused on the challenge of combining desirable traits with resistance to diseases and pests in potato varieties. He discovered that the gene involved in self-compatibility is already present in tetraploid potato varieties, and developed a two-step strategy for breeding that avoids inbreeding depression. This new approach offers a ‘third way’ between conventional breeding and true seed hybrid breeding, and has the potential to improve potato resistance and yield.

Unlocking resistance: Harnessing wild potato relatives to improve late blight protection

A study by researchers at the International Potato Center focused on improving potato resistance to late blight (LB) by incorporating LB resistance from wild potato species into cultivated potatoes. The research involved techniques like rescue pollination and sexual polyploidization to transfer beneficial traits from wild potatoes to cultivated ones. The study resulted in the development of promising sexual and tetraploid hybrids with desirable traits such as high dry matter and LB resistance. These hybrids offer potential for future potato breeding strategies but further research is needed to validate their resistance and address any undesirable traits.

Increased nutritional value in genetically modified potato plant sparks USDA review

The US Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) conducted a review of genetically modified soybean, tomato, and potato plants to assess potential risks. A modified plant, developed by Ohalo Genetics, produces higher levels of beta-carotene for enhanced nutritional value. APHIS determines whether these plants pose a greater plant pest risk compared to non-modified plants and issues a response accordingly.

Unlocking the potato’s potential: A deep dive into the potential of diploid breeding

Researchers at the University of Minnesota reviewed a recent scientific paper on potato breeding, focusing on the transition from autotetraploid to diploid breeding. The complex genetic structure of potatoes has historically hindered yield improvements. The reviewed study proposes strategies to overcome genetic obstacles, such as identifying and avoiding deleterious variants and forming heterotic groups. This could lead to more efficient breeding, improved stress resistance, and better adaptation to environmental and market changes.

Changing the game: How True Potato Seed technology is reshaping agriculture in Kashmir

Irshad Ahmad Dar, a farmer from Pulwama, South Kashmir, has successfully cultivated a potato crop using True Potato Seed (TPS) technology, guided by scientists from Sher-e-Kashmir University of Agriculture Sciences and Technology Kashmir. Suitable for high-altitude areas, TPS involves growing potatoes from seeds, not tubers. The process yields “mini tubers”, which can be replanted to produce regular potatoes. The scientists have developed several high-quality hybrid varieties using TPS, some recommended to the All India Coordinated Project on Potato and local farmers.

U.S. frozen potatoes lead surge in retail sales despite overall volume decrease

Potato retail sales from January-March 2023 increased by 16% in dollar terms in the U.S., despite a 4.4% volume decrease. According to Potatoes USA, frozen potatoes led sales growth, up by 41.9%, followed by instant and fresh potatoes. However, volume sales for instant and refrigerated potatoes declined significantly. All fresh potato types except white, fingerling, and purple saw increased dollar sales. The average price per pound for fresh potatoes rose 18.7%. Bagged potatoes less than two pounds were the only category to see both dollar and volume growth.

Innovation in plant breeding: The promise of hybrid potatoes in enhancing sustainability, food security

A hybrid potato could help bolster global food security, particularly in low- and middle-income countries, according to a book presented at a mini-symposium in Wageningen. Funded by the NWO, the research project involved several institutes including Wageningen University & Research and Solynta. Hybrid seed can be produced faster, requires less material for planting, doesn’t carry diseases, and has longer storage potential. This could significantly impact potato yields in remote regions and respond swiftly to farmers’ needs.
