To control this, rice varieties with new complete resistance genes were bred and released. However, the resistances were broken down within a few years because of the emergence of compatible blast races. To prevent the breakdown, a mixture of near-isogenic lines with different complete resistance genes to blast was first introduced for multilines in 1995 in Japan. For effective control of blast, the author aimed to clarify the degree of blast suppression using multilines. This study was conducted to investigate the mechanisms of blast suppression and was developed as a simulation model for forecasting leaf blast epidemics to analyze the degree of leaf blast suppression in multilines. The autoinfection ratio was a major factor influencing the degree of leaf blast suppression in multilines. A simulation model for rice blast epidemics in multilines was developed, and the parameter of autoinfection was introduced in the model. The calculated data using the model fit well with the observed data of leaf blast development. Parameters of induced resistance, mutation rate and stabilizing selection were also introduced to clarify the mechanisms of leaf blast suppression. In addition, distribution of blast races in multilines was clarified, and a high-throughput method for race differentiation was developed.\n","subitem_description_type":"Abstract"},{"subitem_description":"イネいもち病は、日本で最も重要な病害である。本病を防除するために、新たな真性抵抗性を導入したイネ品種が1960年代に育成・普及されたが、それら抵抗性を侵害するいもち病菌レースが出現・蔓延して罹病化し問題となった。この欠点を克服する方法として、異なる真性抵抗性を個々に持つ同質遺伝子系統を混合栽培するマルチラインが1995年に普及した。しかし、効果的にいもち病を防除するための、マルチラインの利用法は十分明らかでなかった。本研究は、マルチラインにおけるイネいもち病の発病抑制機構の解明と得られた疫学データを利用してシミュレーションモデルを開発し、その抑制機構を解析した。その結果、罹病性系統の葉身上に生じた病斑から同じ罹病性系統の別の葉身へ感染する自己感染比率が発病程度に影響することを明らかにした。これをパラメータとして導入してシミュレーションすると、葉いもち発病推移をよく模擬した。また、発病抑制に関与する誘導抵抗性、突然変異率、安定化淘汰等の要因を解析できた。その他、マルチラインにおけるいもち病菌レースの動態を明らかにし、レース検定の効率化法も開発した。\n","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00001210","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人
