Comparative Study On Main Characters Of Special Sweet Potato Varieties

Research on main characters of sweet potato variety is important basis for the breeding and promotion of new sweet potato varieties.The trial of WAN SHU0515-5, ZHE Shu71, JI XU23, NING SHU51-5, XIANG SHU116, Ji SHU13-10, NING SHU16-2, ZHE SHU259, XU SHU22Special Use the main traits of the sweet potato varieties are compared,Through germination of these species traits and yield traits, agronomic and quality characteristics, study on microclimate systems, access to the following main findings:1High-starch, high-protein and other specialty sweet potato varieties, screening, identified Sprouting Habits good varietiesJIXU23and so on6varieties, and yield traits better varieties ZHUSHU259and so on6varieties.2Comparison of main agronomic characters of sweet potato showed that, between different varieties of sweet potato stem and leaf weight per plant, tubers per plant weight, stem diameter, maximum stem length, number of branches per plant, the number of single strains of tuberization compared with the positive; Filter main agronomic characters influenced by climatic factors such as variety xushu22and so on4varieties; filtering a starch processing of special varieties of potato WANSHu0515-5, JIXU23different types of sweet potato cultivars.3Through analysis, stem diameter, plant stems and leaves, single strain of tuberization, single plant traits such as potato starch and block rates of heavy, dry and fresh potato yield, dry matter yield of relevance is large, there are some dependencies and constraints.4Effects of microclimate on agronomic characters of sweet potato showed that larger climatic factors influence on sweet potato is precipitation, inadequate rainfall and precipitation does not affect the growth of sweet potato in a row.
