槟榔芋新品种‘汀芋1号’选育研究

摘要

‘汀芋1号’是从长汀白芽槟榔芋变异株系中选育而成的槟榔芋新品种，新生芽尖淡红色，母芋呈椭圆筒形，平均单重1．3～1．8 kg，肉色呈槟榔纹状，全生育期180～190 d。在2011－2012年多点区试和生产试验中，‘汀芋1号’平均产量每667 m2分别为1497．6 kg 和1477．3 kg，比对照‘福鼎’槟榔芋增产17．6％和17．4％。该品种品质优、营养成分高，干物率高达39％，氨基酸总量1．44 g·hg－1，蛋白质含量2．28 g·hg－1，维生素含量 C9．88 mg·hg－1，粗纤维含量0．6 g·hg－1，为理想的食用加工型槟榔芋品种。2015年通过福建省农作物品种认定（闽认菜2015009）。%A new betel taro,Tingyu 1,was bred from the mutant plants of the white bud variety.In the multiple-site regional and production trials,Tingyu 1 exhibited an average yield of 1 497.6 kg per 667 m2 in 2011 and 1 477.3 kg per 667 m2 in 2012,which was 17% greater than that of the famed Fuding betel taros.The new variety had good qualities with high nutritional value containing 39% dry matters,1.44% amino acids,2.28% protein,9.88%vitamin C and 0.6% crude fiber.Consequently,Tingyu 1 was considered a desirable new entry as a fresh vegetable for further processing.It was officially certified in Fujian in 2015.
