花生辐照新品种'临花16号'选育与适应性评价OA

This study aims to evaluate the yield performance,quality traits,and regional adaptability of'Linhua 16',a new fresh-eating peanut cultivar developed through irradiation-induced mutagenesis,and to provide a basis for expanding its suitable cultivation regions and promoting its application.Using a sweet local peanut landrace from Hebei Province'Hebei Nongjia Tianhuasheng'as the donor material,'Linhua 16'was bred through 60Co-γ irradiation followed by multi-generation directional selection,and was registered in 2019 under China's National Variety Registration System for Non-major Crops,with the registration number of GPD Peanut(2019)370023.In the Shandong Provincial Regional Trials conducted over two consecutive years(2013-2014),the average pod yield and kernel yield of'Linhua 16'were 5675.51 and 4113.17 kg/hm2,respectively,which were 9.20%and 10.47%higher than those of the control cultivar('Shanhua 9').In 2023,'Linhua 16'was included in a joint national demonstration and validation trial for fresh-eating peanut at nine locations.The results showed that its whole growth period ranged from 115 to 145 d,with an average 100-pod weight of 210.15 g,average 100-kernel weight of 80.48 g,average shelling percentage of 71.57%,and average sucrose content of 6.09 g/100 g.The average pod yield and kernel yield were 4578.45 and 3283.15 kg/hm2,respectively.Overall,'Linhua 16'combines desirable sweetness for fresh consumption,strong potential for high and stable yield,and broad regional adaptability,making it suitable for cultivation in low-altitude temperate regions such as the North China Plain and the Liaodong Peninsula.This study further highlights the importance of exploring and collecting high-quality parental germplasm resources.The mutant population obtained in this study also provides new germplasm and a research foundation for future targeted peanut breeding and genetic improvement.
