中文摘要 | 由三年的田間試驗結果顯示,於向日葵的自交品系(inbreds)或雜交品種(hybrids)之間對菌核病(Sclerotinia sclerotiorum)的抗病性均有顯著的差異。此等試驗也進一步表明屬於抗病性的雜交品種,大多源自於抗病性的親本,而屬於感病性的雜交品種,大多源自於感病性的親本。此一研究證明,測定向日葵的親本(即自交品系)對菌核病的抗病性是雜交育種上的一項重要策略。 |
英文摘要 | A 3-year field study was conducted to compare sunflower inbreds and hybrids for resistance to sclerotinia wilt caused by Sclerotinia sclerotiorum. Significant differences in resistance to sclerotinia wilt were found among the sunflower inbreds and hybrids tested in each year. The study reveals that the nature of resistance to sclerotinia wilt is inheritable as the hybrids derived from resistant inbreds were more resistant than those hybrids derived from susceptible parents. The study concludes that screening parental inbred lines for resistance to S. sclerotiorum is an important step in developing sunflower hybrids with improved resistance to sclerotinia wilt. |
