Breeding and Key Trait Analysis of a High-quality Table Potato Variety'Minlongshu 1'
摘要
Abstract
'Minlongshu 1'was developed through sexual hybridization between female parent'C146'and male parent'72'(Yin),followed by multiple generations of pedigree selection and evaluation in order to develop a new potato variety suitable for winter cropping in Fujian Province with high quality,high yield,and excellent commercial traits.In 2023,it was registered as a non-major crop variety by the Ministry of Agriculture and Rural Affairs with the registered number GPD potato(2023)350107.In the variety comparison trial,its fresh tuber yield reached 2 496 kg/667m2,representing a 13.6%increase over the control variety'Favorita'(CK).While the average yield across two years of provincial regional trials was comparable to that of the control,a 52.7%yield increase was observed at the Longyan trial site,demonstrating its significant yield potential under specific environmental conditions.'Minlongshu 1'is a medium-late maturing variety with a 91 days growth period.The tubers are oval in shape,with yellow skin,light yellow flesh,smooth skin,and very shallow eyes.The marketable tuber percentage was 84.8%,and tuber shape uniformity was significantly better than that of the control.The dry matter content was 20.0%,being 1.4 percentage points higher than that of the control.It exhibited excellent eating quality,with a sweet taste upon cooking.Its tubers contained 3.09%crude protein,0.44%reducing sugar,and 43.1 mg per 100 g of vitamin C.Disease resistance evaluations showed moderate resistance to early blight,moderate susceptibility to late blight,susceptibility to potato virus X,and moderate resistance to potato virus Y.'Minlongshu 1'demonstrates broad market potential for Fujian's winter cropping regions and similar ecological zones.关键词
