木薯新品种桂薯1505的选育及栽培技术
Breeding and Cultivation of a New Cassava Cultivar Gui 1505
摘要
Abstract
The high-yield variety XX 048 was used as the maternal parent,and the asexual offspring of F1 excellent sin-gle plants through open pollination and hybridization was obtained to select a new variety of cassava with good plant type,high yield,high starch,and wide adaptability.After a series of systematic breeding procedures such as sowing and seedling cultivation,field transplantation,single plant selection,single row experiment,line ratio experiment,regional experiment,and production experiment,a new cassava variety Gui 1505 with high yield,high starch,low hydrogen cyanide,and strong adaptability for both fresh food and processing was developed.The variety is an upright plant type,with mature stem outer skin being gray white and inner skin being green.The tubers are distributed irregularly and concentrated,with a cylindrical conical shape.The outer skin of the tubers is light brown,the inner skin is light red,and the flesh of the tubers is white.The average fresh potato yield of Gui 1505 in regional and production trials reached 46.68 t/hm2 and 49.69 t/hm2,respectively,both higher than the control NZ199.The starch content of the root tuber was more than 29.05%.The average hydrogen cyanide content in fresh potatoes was 20‒30 mg/kg,which is lower than the control.The field identification result of mite resistance is moderate.It is suitable for planting in major cassava pro-ducing areas such as Guangxi,Guangdong,and Yunnan.This study provides new germplasm resources for China to achieve high-quality cassava production,which is of great significance for promoting potato farmers'income and enter-prise efficiency.关键词
