Determining the optimal population density of sugarbeet crops in England
Jaggard, K. W.; Qi, Aiming; Milford, G. F. J.; Clark, C. J. A.; Ober, E. S.; Walters, C.; Burks, E. (2011-02)Eleven experiments were conducted at seven sites in England from 2006 to 2008 to investigate the sugarbeet yield response to plant populations resulting from different seed rates. Experiments were made on loamy sand, sandy ... -
Development of new quantitative physiological and molecular breeding parameters based on the sugar beet vernalization intensity model.
Chiurugwi, Tinashe; Holmes, Helen F.; Qi, Aiming; Chia, Tansy Y. P.; Hedden, Peter; Mutasa-Gottgens, Euphemia (2013-08)Sugar-beet crops, Beta vulgaris spp. vulgaris (L), suffer from premature bolting and flowering as a consequence of prolonged exposure to cold conditions (vernalization). This reduces crop yield and quality and could be ... -
