高产优质多抗食用加工型花生新品种龙花172的选育OA

To solve the problem of the lack of new edible processing-type peanut varieties in the Longyan salty crisp peanut industry,cross-breeding technology was adopted.A new high-yield,high-quality edible processing-type peanut variety Longhua 172,was bred by the pedigree method,with Quanhua 7 as the female parent and Shanyou 188 as the male parent.The results of regional trials of new spring peanut varieties in Fujian Province from 2020 to 2021 showed that:(1)Longhua 172 had excellent yield potential and stability.Its yield ranked first among all tested varieties in both years of regional trials,with an average pod yield of 4 248 kg·hm‒2 and an average kernel yield of 2 724.45 kg·hm‒2 in two years,increasing by 19.03%and 20.73%respectively compared with the control variety Quanhua 7,and the yield increase was extremely significant.(2)It had strong drought resistance,waterlogging tolerance,and lodging resistance.(3)It was highly resistant to leaf spot and rust and moderately resistant to bacterial wilt.The quality analysis results showed that Longhua 172 had a protein content of 28.6 g·hg‒1,oil content of 45.4%,sucrose content of 9.4 g·hg‒1,oleic acid content of 40.3%,linoleic acid content of 38.3%,and oleic acid-linoleic acid ratio(O/L ratio)of 1.05.The protein content of Longhua 172 met the first-class protein index(≥26%)specified in the national agricultural industry standard NY/T 1067-2025 Edible Peanuts and the protein index(≥26.5%)specified in the Fujian local standard DB35/T 867-2008 Geographical Indication Product—Longyan Salty Crisp Peanuts.Its sucrose content was much higher than the reference standard for high-sucrose peanuts(≥6%),and the oil content was moderate.In summary,Longhua 172 has the characteristics of high yield,excellent quality,strong stress resistance and disease resistance,wide adaptability,and superior processing properties,with high nutritional and processing value.Its com-prehensive traits are better than those of its parents,Quanhua 7 and Shanyou 188,making it suitable for processing products such as Longyan salty crisp peanuts.Longhua 172 passed the national registration of nonmajor crop varieties[GPD Peanut(2023)350023]in 2023 and was selected as a leading agricultural variety in Fujian Province in 2024.The popularization and application of Longhua 172 in Fujian Province will play a positive role in promoting the adjustment of the peanut industrial structure in Fujian Province and the high-quality development of the Longyan salty crisp peanut industry.
