Abstract

The citrus vegetative propagation by stem cuttings depends on factors such as genetics, age, vigor, woodiness, growth regulators, environment and nutrition. Lemons (Citrus limon), acid limes (Citrus aurantifolia) and citrons (Citrus medica) root very easily. Plant cuttings from the sweet orange (Citrus sinensis), mandarins (Citrus reticulata) and Poncirus trifoliata are more difficult to root. The objective of this study was to detect quantitative trait loci linked to the rooting of citrus stem cuttings in F 1 hybrids obtained from a crossing between Citrus sunki x Poncirus trifoliata. The semi-woody cuttings were treated with 1 g/L indole-3-butyric acid for 10 minutes and cultivated in citrus substrate under a mist environment. QTLs were identified by the composite interval mapping strategy. Two QTLs were detected for the rooting trait in plant cutting, in the P. trifoliata map.

柑桔与三叶Poncirus杂种生根插条的QTL定位

柑桔扦插无性繁殖取决于遗传、年龄、活力、木质性、生长调节剂、环境和营养等因素。柠檬(Citrus limon)、酸橙(Citrus aurantifolia)和香橼(Citrus medica)很容易生根。甜橙(Citrus sinensis)、柑橘(Citrus reticulata)和三叶松(Poncirus trifoliata)的植物插枝更难生根。本研究的目的是检测与柑橘茎插条生根相关的数量性状位点，这些位点是由sunki柑橘与Poncirus trifoliata杂交获得的f1杂种。用1 g/L吲哚-3-丁酸处理半木本扦插10 min，在柑桔基质中雾环境培养。采用复合区间映射策略识别qtl。在三叶草图谱中检测到2个与植物扦插生根性状相关的qtl。

期刊介绍： The CBAB – CROP BREEDING AND APPLIED BIOTECHNOLOGY (ISSN 1984-7033) – is the official quarterly journal of the Brazilian Society of Plant Breeding, abbreviated CROP BREED APPL BIOTECHNOL. It publishes original scientific articles, which contribute to the scientific and technological development of plant breeding and agriculture. Articles should be to do with basic and applied research on improvement of perennial and annual plants, within the fields of genetics, conservation of germplasm, biotechnology, genomics, cytogenetics, experimental statistics, seeds, food quality, biotic and abiotic stress, and correlated areas. The article must be unpublished. Simultaneous submitting to another periodical is ruled out. Authors are held solely responsible for the opinions and ideas expressed, which do not necessarily reflect the view of the Editorial board. However, the Editorial board reserves the right to suggest or ask for any modifications required. The journal adopts the Ithenticate software for identification of plagiarism.
