The Relationship Between Cell Size, Yield, and Sucrose Concentration of the Sugarbeet Root

Natural variation within the genus Beta and its possible use for breeding sugar beet: A review

“…In sugar beet yield as well as cell size were shown to be negatively correlated with sucrose content (Doney, 1979 ;Doney et al ., 1981) . Doney & Theurer (1983) showed that cell diameter and sucrose concentration showed little midparent heterosis, whereas a later study (Doney & Theurer, 1985) allowed the conclusion that beet root heterosis is due primarily to increases in cell number .…”

Belowground plant development measured with magnetic resonance imaging (MRI): exploiting the potential for non-invasive trait quantification using sugar beet as a proxy

“…The rings with their phloem and parenchyma zones are critical for providing transport and sugar storage capacities (Artschwager, 1926; Draycott, 2006). No clear correlation with sugar yield was found for simple traits such as number and width of rings or parenchyma cell size at harvest (Draycott, 2006), even though several studies argued that, with shorter distances between phloem and storage tissues, a higher sucrose content should be achievable (Milford, 1973; Wyse, 1979; Doney et al, 1981). Also cDNA cloning of extracellular and vacuolar sucrose cleaving enzymes revealed a change in the mechanisms of the functional unloading pathways during the first weeks of beet development, and transcript profiles revealed developmental and metabolic changes at similar or later age (Godt and Roitsch, 2006; Bellin et al, 2007; Trebbi and Mcgrath, 2009).…”

“…Non-invasive approaches with rhizotrons (Gregory, 2006; Neumann et al, 2009) are not well suited to study solid volumetric (3D) structures or gain anatomical information on ring development. Linking structure and function and correlating them to yield or yield stability has proven to be difficult (Doney et al, 1981; Hoffmann, 2010), possibly due to the lack of detailed developmental data.…”

Sucrose Production as Affected by Root Yield and Sucrose Concentration of Sugarbeets

“…Increasing root yields by plant breeding, genetic selection, nitrogen (N) fertilization, agronomic practices, and environmental conditions will generally decrease sucrose concentration (5,14). Milford (13) and Doney (7,8) where S ? smi is the sucrose yield change attributed to PSDM, S imi is the sucrose yield change attributed to dry matter, SWt 1 (PSDM 1 /100) x DM yd 1 , SWt 2 -(PSDM2/100) x DM yd 2 , SWt I E"2 (PSDM 1 /100) x DM yd 2 , DM yd is the dry matter yield, subscript 1 is the lower sucrose yield treatment, and subscript 2 is the higher sucrose yield treatment.…”
