The invention discloses a thrip resistance identification device and application. The device comprises an inoculation barrel, a preservation substrate is laid at the bottom in the inoculation barrel, an isolation structure with one or more through holes covers the preservation substrate, and a sealing structure with one or more air holes covers an opening in the top of the inoculation barrel. When the device is used, the whole plant does not need to be cultivated, in-vitro flowering branches can be picked for identification, rapid screening of large-scale germplasm resources can be achieved, and repeatability and consistency of experimental results are good. Meanwhile, when the device is used, buds and functional leaves of in-vitro flowering branches are reserved, the actual feeding part of the Frankliniella occidentalis is simulated, and compared with in-vitro leaf inoculation, the real resistance level can be better reflected. The device has the advantages of easily available materials, low cost and strong operability, can be used for identifying the resistance of the Frankliniella occidentalis of various materials such as chrysanthemum and related wild species, cultivated species, breeding offspring and the like, provides a high-quality parent material for insect-resistant breeding, can be used for researching an insect-resistant mechanism, and is suitable for popularization and application in basic breeding units.

A new and distinct Rudbeckia hirta plant named ‘Summer Sienna’ characterized by its semi double inflorescence with deep orange yellow and dark red ray florets, medium rounded upright growth habit, and excellent vigor from spring through fall.

A new and distinct variety of Rudbeckia plant having a compact growth habit and large, yellow-orange and reddish-brown bicolored blooms with a brown center.

A new and distinct variety of Rudbeckia plant having a compact growth habit and large, yellow-orange and reddish-brown bicolored blooms with a brown center.

The present disclosure provides a cytoplasmic male sterile Rudbeckia plant. The present disclosure also provides a method for conferring cytoplasmic male sterility to a Rudbeckia plan. The method may comprise introducing, as a cytoplasmic male sterility gene, at least one polynucleotide into a Rudbeckia plant of interest.

A new cultivar of Rudbeckia plant named ‘RUDBBCH767’ that is characterized by its strong and sturdy stems, its compact plant habit, its floriferous blooming habit, its inflorescences with 4 whorls of ray florets, its large inflorescences, and its fast propagation and production time.

A new Osteospermum plant particularly distinguished by purple flowers, with an upright habit, is disclosed.

The invention discloses a method for creating a novel chrysanthemum germplasm with high linarin content based on distant hybridization between opisthopapus and chrysanthemum, which comprises the following steps: inducing ovules after pollination for 13-18 days to generate calluses and obtain distant filial generation plants by combining artificial cross breeding with an immature embryo rescue technology, and carrying out morphological and cytological identification to obtain the novel chrysanthemum germplasm with high linarin content. And obtaining a true hybrid filial generation. The content of linarin in inflorescences and leaves of true hybrid filial generations is obviously increased and is obviously higher than that of the female parent Jinlingzirobe. The invention provides a new way for efficient utilization of opisthopapus and chrysanthemum germplasm resources, and has significant breeding and application values.
