Mr. Sun Shulin, a dedicated farmer breeder from Zhaoyuan, Shandong Province, has made remarkable progress in developing an extraordinary variety of peanuts through mutation breeding techniques. By using the parental strain P12 and subjecting it to intense mutagenic conditions, he successfully created a series of super-large peanut varieties. These peanuts are not only visually impressive but also highly productive and flavorful. The characteristics of these super-large peanuts include strong seedlings with rapid growth, large and thick leaves that are nearly twice the size of regular peanuts, and sturdy, hard stems that reach a height of 40–45 cm. The plants flower early, starting around 23 days after emergence, with a high number of flowers. Each plant can produce between 30 to 50 pods, and the fruits are exceptionally large—reaching an average weight of 540 grams, with some even reaching up to 675 grams. A single mu (approximately 667 square meters) can yield 500–600 kg, sometimes even exceeding 700–800 kg. The growing period is about 135 days under normal conditions, and the quality is outstanding, with a rich aroma and a sweetness that rivals chestnuts and walnuts. They are so delicious that people often find themselves wanting more after just one bite. The seeds are also notably large, weighing between 160.87–187.5 grams, with the largest reaching up to 235–250 grams—more than double the size of most domestic large peanut varieties. This unique variety is rare not only in China but also globally, and it could potentially be a contender for the Guinness World Records. As shown in the photos, the difference between regular and super peanuts is striking, and many people are amazed by their size. Cultivating these super-large peanuts requires careful attention to environmental and nutritional needs. Proper field management, including irrigation and fertilization, plays a crucial role in achieving high yields. Water should be supplied regularly during the flowering and fruiting stages, while drainage must be ensured to prevent waterlogging. Fertilization should be done according to specific formulas, balancing nitrogen, phosphorus, and potassium with organic matter where possible. Top-dressing with urea and foliar sprays of potassium dihydrogen phosphate can significantly boost yield and quality. Sowing time is also important. Late sowing in May or June helps avoid issues like rotting and pests, ensuring better germination and healthier plants. Seed treatment with solutions like Vicone or 3721 rooting fluid can improve seed viability and resistance. In addition, using insecticides in the planting furrow helps protect against underground pests. Field management involves controlling weeds and diseases. For instance, if leaf spot disease appears, timely application of fungicides is essential. Using carbendazim later on helps preserve leaf health, extending the functional period of the leaves and ultimately increasing yield. In summary, Mr. Sun’s super-large peanuts are a groundbreaking achievement in agricultural innovation, offering both exceptional size and flavor. With proper care and techniques, farmers can achieve remarkable results, making this variety a true marvel in the world of agriculture.
