以本地甘薯实生种子做对照,将引进的国际马铃薯中心(CIP)甘薯实生种子及其后代品系进行萌芽性、生长势、生产力、抗病性、品质等性状的综合鉴定筛选,结果表明,CIP实生种子的出苗率、移栽率及初选、复选、品系比较等各级试验的入选率分别为60.35%、55.97%、6.30%3、2.18%、16.67%,本地实生种子分别为63.38%、48.97%、4.67%、32.20%、25.76%;筛选结果CIP实生种子和本地实生种子差异不显著。从CIP实生种子后代中筛选出了6个优良品系作为育种材料利用。通过引进CIP甘薯实生种子,在国内鉴定筛选,可以丰富国内甘薯种质基因库,提高育种效率。
The results showed that CIP seedlings and their progeny lines of the International Potato Center (CIP) were screened for comprehensive germination, growth vigor, productivity, disease resistance, quality and other characteristics by using the native sweet potato seed as control. The selection rate of seed germination rate, transplanting rate, primary election, check and comparison of strains were 60.35%, 55.97%, 6.30% 3,2.18% and 16.67% respectively, and the local seed yield was 63.38% 48.97%, 4.67%, 32.20% and 25.76% respectively. There was no significant difference between CIP seed and native seed. Six elite lines of CIP seed were selected as breeding material. Through the introduction of CIP sweet potato seed, identification in the domestic screening, you can enrich the domestic sweet potato germplasm bank, improve breeding efficiency.
