The Queensland strawberry breeding program aims to sustainably increase profitability for the producer by selecting superior genotypes. To be effective and efficient, selection must account for several traits simultaneously and focus on: 1) the most

China ( Dirr, 2016 ; Hu, 1989 ). It has been widely used as an ornamental and traditional medicine in China, Japan, and Korea ( Chen et al., 2018 ; Jo et al., 2019 ; Tezuka et al., 2013 ). To date, no selections or cultivars of the species have been

Two lemon [Citrus limon (L.) Burm.] cultivar selection trials are being conducted at the Yuma Mesa Agriculture Center in Somerton, Ariz. Some selections in these trials include: `Allen Eureka', `Berna', `Cook Eureka', `Cascade Eureka', `Cavers Lisbon', `Strong Lisbon', `Femminello Comune', `Lapithkiotiki', `Limoneira 8A Lisbon', `Limonero Fino 49', `Monroe Lisbon', `Primofiori', `Santa Teresa', `Walker Lisbon', and `Villafranca'. Selections that have had superior yields include `Cascade Eureka', `Cook Eureka', `Strong Lisbon', `Limoneira 8A Lisbon', `Limonero Fino 49', `Primofiori', `Femminello Comune', and `Villafranca'. Fruit size data suggest that `Limonero Fino 49' has consistently good fruit size, and consistently larger fruit than `Limoneira 8A', the industry standard. `Cavers Lisbon' and `Femminello Comune' also have good fruit size. `Lapithkiotiki' also had large fruit size, but its shape was unacceptably elongated. We also found significant differences in peel thickness and juice pH among the selections. `Santa Teresa' had significantly lower juice pH and a thinner peel than some of the other selections under evaluation.

Man's breeding and selection of woody ornamentals is, by no stretch of the imagination, a novel pursuit, but has employed succeeding generations of plantsmen for many centuries. Currently, selection of woody ornamentals that depends on government or industry funding is inevitably stimulated by cultural or disease problems with existing species or cultivars, by changing consumer needs, or by recognition of a market demand for superior or novel plants. The worth of this work frequently is judged in terms of its potential economic benefit. Speculative breeding and/or selection of esoteric plants, a traditional pursuit of the enthusiastic horticulturist, is now difficult for anyone other than the keen amateur to sustain.
