鲜食型甘薯新品种广薯133的选育与品质评价
Breeding and Quality Characterization of a New Table-use Sweet Po-tato Variety Guangshu 133
摘要
Abstract
The self-bred cultivar Guangshu 79 from Crop Research Institute,Guangdong Academy of Agricultural Sci-ences was used as the female parent and the line Guangshu12-44 as the male parent for sexual hybridization to breed a table-use sweet potato variety with superior eating quality and good marketability.Through seedling selection,re-selection,variety comparison tests,and two-year multi-location regional trials,a new high-quality table-use sweet potato variety,Guangshu 133,was developed.The variety produces swollen spindle-shaped storage roots with pur-plish-red skin and medium-yellow flesh.Root setting is concentrated and uniform,with an average of 5.23 roots per plant and a marketable root rate of 86.28%,indicating favorable commercial quality.In the two-year multi-location re-gional trials,the average fresh root yield,dry root yield,and starch yield of Guangshu 133 was 29.94 t/hm2,10.71 t/hm2,and 6.36 t/hm2,respectively,which was 28.95%,7.03%and 2.75%lower than those of the control cultivar Guangshu 87.Quality analysis showed that the dry matter content of the roots was 34.97%,and the starch content on a dry-weight basis was 591.23 g/kg,including 60.57 g/kg amylose and 530.66 g/kg amylopectin.The content of soluble sugar,re-ducing sugar,crude protein,total flavonoids,and total phenols was 127.07,28.65,36.93,6.29,4.38 g/kg,respectively.Eating quality evaluation indicated that,after steaming,the roots had a fine mealy texture,well-balanced sweetness and aroma,and a smooth mouthfeel,with a taste score of 90,significantly higher than that of the control cultivar Guangshu 87(80).Disease resistance evaluation indicated that Guangshu 133 exhibited moderately resistant to root rot and typeⅠ sweet potato wilt.In conclusion,Guangshu 133 is a new table-use sweet potato variety characterized by excellent eating quality and good marketability,achieving quality improvement with a moderate trade-off in root yield.关键词
