中文摘要 | 以20個落花生品種(系),連續2年4期作在農業試驗所之農場進行試驗,以探討栽培季節對落花生品種間莢果黑斑病之影響。結果顯示莢果黑斑病罹病度極容易受品種、年度及期作之影響;感病及中等抗病的品種(系)會因連續栽培而增加莢果黑斑病罹病度之趨勢,而較抗病之品種(系)影響較小;期作間之相關只有秋作與其後之期作間具顯著相關性;外表型相關,只有在春作莢果黑斑病罹病度與葉斑病呈顯著正相關,而與莢果及籽粒產量則呈顯著負相關。 |
英文摘要 | For evaluating crop season effect on pod rot disease, 20 peanut varieties were cultivated continuously at a TARI field for four crops in two years. It resulted that the varieties, crop seasons and years had interactions with pod rot severity. Susceptible and moderate resistant varieties were more serious pod rot in continuous cultivation seasons, but resistance varieties were not. The crop seasons correlation were significant for fall crop will after fall crops. The phenotypic correlation was positive for pod rot severity with leaf spot disease, but negative with pod and kernel yields, in spring crop. |
