The invention discloses a gibberellic-disease-resistant wheat-roegneria ciliata disomatic alien addition line DA3Sc as well as a breeding method, a molecular marker and application thereof. The method comprises the following steps: by taking a short antibody 58 as a female parent and taking a Chinese spring-roegneria ciliata disomatic alien addition line DA3Sc as a male parent, selfing F1, detecting a single plant containing a 3S chromosome in F2 through a molecular marker with 3S chromosome characteristics and a fluorescence in-situ hybridization technology, and then bagging and selfing to obtain an F3 generation; in the F3 generation, detecting a homozygous single plant containing the whole 3S chromosome in the F3 through a GISH/FISH technology; and carrying out wheat scab resistance identification on pure and synthetic plants. The wheat-roegneria ciliata disomatic alien addition line DA3Sc obtained through breeding can be used for wheat gibberellic disease resistance breeding; the primer ...

The invention discloses a wheat stripe rust resistant common wheat-roegneria ciliate translocation line, a breeding method, a molecular marker and application. The method comprises the following steps: treating a castrated plant of a common wheat-roegneria ciliata disomatic alien addition line DA2Sc and pollinating Nannong 0686 pollen by using 60Co-gamma radiation, performing GISH/FISH analysis on root tip cell mitosis metaphase chromosomes of progeny seeds of the common wheat-roegneria ciliata disomatic alien addition line DA2Sc, performing stripe rust identification, and creating a wheat-roegneria ciliata small fragment translocation line with high stripe rust resistance. And screening to obtain an IT marker capable of specifically tracking the disease-resistant fragment. The translocation line bred by the method has high resistance to stripe rust, and the translocation section provides a new anti-disease gene source for genetic improvement of wheat stripe rust.

Breeding method of wheat-roegneria ciliate powdery mildew resistant T1ScS.1BL translocation line, molecular marker and application

Номер: CN116004885A

The invention discloses a breeding method of a wheat-roegneria ciliata powdery mildew-resistant T1ScS.1BL translocation line, a molecular marker and application of the molecular marker. The wheat-roegneria ciliate translocation line T1ScS.1BL obtained through breeding can be used for wheat powdery mildew resistance breeding; the primer of the molecular marker can be used for identifying whether the wheat-roegneria ciliata structure variant contains the 1Sc short-arm chromosome or not, so that the disease-resistant breeding efficiency is improved.
