Breeding Potential of Root Chicory (Cichorium intybus L. var. sativum)

Abstract

The objective of this study was to investigate the breeding potential of the inulin-containing root chicory which has potential as a new industrial crop. Polycross families and reference varieties were grown in field experiments at 3 locations to assess their performance and the amount of variation available for breeding. Significant variation between polycross families for all characters except for glucose content and the ratio total sugar/dry matter content was observed. Compared to 'Fredonia', 12 out of 72 polycross families gave between 15 % and 24 % more total sugar yield. Preliminary estimates for the heritability of two yield components were calculated by means of the parent-offspring regression analysis. Additive genetic variance seems to determine the inheritance of fructose and total sugar content. All findings suggest that the total sugar yield of root chicory can be considerably increased by breeding.

Extraction, degree of polymerization determination and prebiotic effect evaluation of inulin from Jerusalem artichoke

“…After that, percent of inulin begins to decrease gradually and reached 7.3% at the last time point. Compared with previous reports (Frese, Dambroth, & Bramm, 1991;Liu et al, 2014;Yang et al, 2010), the yield of inulin extracted from Jerusalem artichoke was greater than or equal to the yield in other species (i.e., chicory, burdock, Morinda officinalis). This indicates that Jerusalem artichoke could be a resource to produce inulin in China.…”

Phylogenetic relationships of industrial chicory varieties revealed by RAPDs and AFLPs

“…In field experiments, yield of dried root mass ranged from 10.6 to 16.5 t ha -1 and inulin yields from 8.0 to 12.6 t ha -1 (Frese, 1993;Meijer et al, 1993). High genetic variances for yield and inulin content between varieties were reported (Coppens D 'Eeckenbrugge et al, 1989;Dutilleul et al, 1990;van Herck et al, 1992;Steinmayr, Sarea, Austria, pers comm) suggesting that the yield potential can still be increased by breeding (Frese et al, 1991). Breeding is complicated by the strict outcrossing nature of this species, its biennial character, the total or partial self-incompatibility and the lack of a reliable cms-system (Eenink, 1981;Rambaud et al, 1993 (Vermeulen et al, 1994). The variability between varieties of chicory using isozyme markers was found to be low (Baes and Van Cutsem, 1993a, b (Bellamy et al, 1995(Bellamy et al, , 1996 …”

The Effect of Cantharidin and Endothall on Gene Expression of the Key Regulating Enzymes in Cichorium Intybus L.

“…All parts of chicory, including roots and leaves, have medicinal values, and fresh leaves contain a lot of vitamin C, and its consumption improves gingivitis, which is caused by a deficiency of this vitamin ( Pushparaj et al, 2007;Street et al, 2013;Al-Snafi, 2016). Chicory grows in relatively moist roadsides, barren areas, and low slopes from Europe to Sweden, western and central Asia and North Africa, and semi-wild in North America ( Frese et al, 1991;Das et al, 2016). This plant is distributed in different regions of Iran, including the low slopes of Alborz, around Tehran, Lahijan, and Rasht, mountainous areas of Khorasan.…”
