The new blueberry plant variety ‘IBUGA002’ is provided. ‘IBUGA002’ is a commercial variety that does not require chilling hours. The variety is produced from open pollination of the ‘TH-909’ variety (not patented). ‘IBUGA002’ displays a semi-erect to prostrate plant with strong vigor, provides early berry ripening, displays clustered inflorescence, and exhibits large fruit that are firm.

The new hop plant variety ‘NZH-3077’ is provided. The new variety was produced by open pollination of ‘Riwaka’ (female parent, not patented) in the course of a planned breeding program. ‘NZH-3077’ is characterised by having large cones with medium compactness which are early-season maturing. ‘NZH-3077’ may be used for brewing purposes.

This invention relates to the field of rapeseed breeding technology, specifically to a method for selecting "double-low" Chinese rapeseed varieties based on open pollination. The method involves: hybridizing high-erucic acid, high-glucosinolate parent lines with low-erucic acid, low-glucosinolate parent lines to create F1 hybrid combinations; isolating the F1 generation for propagation and open pollination to obtain the F2 generation segregating population; isolating the F2 generation for propagation, selecting individual plants, and determining erucic acid and glucosinolate content; retaining "double-low" individual plants for open pollination based on erucic acid and glucosinolate results to obtain F3 generation seeds; subsequent generations are planted under isolated propagation conditions, and selection is performed within each generation using open pollination according to breeding objectives until genetic equilibrium is reached. The advantages of this invention are: (1) improved selection efficiency and accuracy of erucic acid and glucosinolate traits in Chinese rapeseed; (2) the selected low-erucic acid, low-glucosinolate breeding populations are not generated through self-pollination; (3) improved selection efficiency of other important agronomic traits in Chinese rapeseed.

The new blueberry plant variety ‘IBUGA001’ is provided. ‘IBUGA001’ is a commercial variety. The variety is produced from open pollination of the ‘TH-909’ variety (not patented). ‘IBUGA001’ displays a semi-erect to prostrate plant with strong vigor, provides very early berry ripening, and exhibits large fruit with medium sweetness and medium firmness.

The invention provides a method for obtaining white pulp genotype tetraploid loquats based on open pollination of white pulp triploid loquats. According to the method, white-flesh triploid loquats (such as' Huayu seedless No.1 ', Q16 and Q21) capable of fruiting (at least one single flower spike fruit on average) under the open pollination condition are taken as female parents and mixed with white-flesh diploid loquats for field planting, and open pollination seeds of the triploid loquats are taken as materials for screening to obtain white-flesh genotype tetraploid loquats.
