4 results about "Apple scab" patented technology

The application belongs to the technical field of apple molecular breeding, and particularly relates to application of a detection reagent of a molecular marker related to apple anthracnose leaf blight resistance, the molecular marker being Del772, Del231 and SNP947, the nucleotide sequence of Del772 being shown as SEQ ID NO. 1, the nucleotide sequence of Del231 being shown as SEQ ID NO. 4, and the nucleotide sequence of SNP947 being shown as SEQ ID NO. 5, the application further develops the detection reagent of the molecular markers Del772, Del231 and SNP947, the detection reagent can detect or identify the resistance of apples to anthracnose leaf blight, and a method for identifying the resistance of apples to anthracnose leaf blight is developed, thereby providing a new way for breeding disease-resistant apples.

The present application belongs to the technical field of apple planting, and discloses a method for preventing and controlling apple bitter scab, which comprises the following contents: (1) nitrogen fertilizer regulation, adopting a strategy of applying fertilizer in stages, including application of base fertilizer in autumn, application of topdressing fertilizer in spring, and nitrogen limitation management in summer; (2) new shoot regulation, setting differentiated new shoot growth thresholds according to the age stages of fruit trees; (3) fruit regulation, controlling the fruit retention position and amount through thinning flower and fruit management, and controlling the fruit size within a preset horizontal diameter range; (4) whole-cycle calcium supplementation, establishing a three-dimensional calcium supplementation system including foliar spraying in the growing season, root zone application, and post-harvest treatment. The present application effectively guarantees the quality and yield of apples, reduces the influence of bitter scab on the growth and development of fruit trees, thereby realizing high-quality, high-yield and high-efficiency of apples, and promoting the high-quality development of the apple industry.

The application discloses a structural variation marker in apple scab resistance breeding and application thereof. The application claims the application of a specific fragment as a molecular marker in detection or assisted detection of apple plant resistance to scab; the nucleotide sequence of the specific fragment is as shown in SEQ ID No. 1 or positions 393-1166 of SEQ ID No. 1. Experiments prove that the absence and presence of the SCAB-R fragment (SEQ ID No. 1) can be used to quickly screen the scab resistance potential of natural plants or hybrid offspring, which is of great significance to the scab resistance breeding of apple plants.
