“…Similar work confirmed substantial conservation of gene order among chromosomes of wheat, barley, and rye (Devos et al 1992(Devos et al , 1993a. Recently, comparative maps have been developed for rice, maize, and wheat Kurata et al 1994) and a surprising degree of genome conservation was detected among these diverse species.…”

“…Loci involved in rearrangements should not be used in consensus maps unless the chromosome region involved is carefully characterized. In view of the chromosomal rearrangements known to be present in other chromosome groups of the Triticeae species analyzed (Devos et al 1993a), group 1 chromosomes seem to be the most highly conserved. It is possible that future more detailed genetic and physical maps may reveal small rearrangements among these species.…”

“…RFLP linkage maps also exist for barley (Heun et al 1991;Kleinhofs et al 1993;Schondelmaier et al 1993;Graner et al 1994), rice (Causse et al 1994), oat (O'Donoughue et al 1992; L.S. O'Donoughue, in preparation), and rye (Baum and Appels 1991;Devos et al 1993a;Philipp et al 1994).…”

“…Based on the maps presented in this paper, it is likely that Xpsrl61 and Xpsr393 in Triticum are orthologous to the Xpsrl61 and Xpsr393 locus located proximally to XTri in the Devos et al ( 1 9 9 3~) map, therefore this position was used in the consensus map. The relative positions of Xpsr937 on 1R (Devos et al 1993a) and the T f l a map are also inconsistent.…”

Group 1 chromosomes of the Triticeae tribe have been studied extensively because many important genes have been assigned to them. In this paper, chromosome 1 linkage maps of Triticum aestivum, T. tauschii, and T. monococcum are compared with existing barley and rye maps to develop a consensus map for Triticeae species and thus facilitate the mapping of agronomic genes in this tribe. The consensus map that was developed consists of 14 agronomically important genes, 17 DNA markers that were derived from known-function clones, and 76 DNA markers derived from anonymous clones. There are 12 inconsistencies in the order of markers among seven wheat, four barley, and two rye maps. A comparison of the Triticeae group 1 chromosome consensus map with linkage maps of homoeologous chromosomes in rice indicates that the linkage maps for the long arm and the proximal portion of the short arm of group 1 chromosomes are conserved among these species. Similarly, gene order is conserved between Triticeae chromosome 1 and its homoeologous chromosome in oat. The location of the centromere in rice and oat chromosomes is estimated from its position in homoeologous group 1 chromosomes of Triticeae.

“…These homoeologies have now been reflned even further with the advent of molecular markers. These have deflned, in very great detail, the relationships between entire chromosomes as well as regions of chromosomes for the cereal group as a whole, exposing relic translocations and inversions in the process (Devos et al, 1993;. This comparative genetic mapping is having a major impact on many aspects of analysis, enabling structurally related genes identifled in one cereal species to be quickly pin-pointed in another.…”

Genetic analysis of some flowering time and adaptive traits in wheat

SUMMARYThe present understanding of the genetic control of flowering m wheat is reviewed. Although this information will continue to be of value in breeding and in recognizing the role such genes have had in adapting the wheat crop to global agriculture, its use in defining the processes responsible for flowering will be limited. Progress here will depend on developments in model plant systems such as Arabidopsis, where methods for isolating genes are much more advanced than in wheat. These developments, which have already started, will probably be used to establish homologies between the genes for flowering within the cereals, as well as more widely. An understanding of the flowering process in wheat is likely to emerge from this approach. In the meantime, there are some unknowns in the genetics of flowering in wheat which need to be resolved. These include the identification of a gene(s) on the group 4 chromosomes of wheat which is homoeoallelic with the gene Sh in barley. Also, the proposed gene(s) delaying flowering and located on the group 6 chromosomes needs to be recognized and mapped. Similar needs occur for the group 1 chromosomes as well as the resolution of whether or not Vrn5 is correctly positioned on chromosome 7BS.

PREFACEThis Handbook is the result of a combined effort by several current and previous cassava researchers at CIAT to review and summarize the most important results of cassava research during the past 40 years. Most of the chapters are based on the various presentations during the Regional Cassava Training Course, held in Thailand from October 6 to 17, 2008. This course was organized upon the realization that many people that were actively involved with cassava research in the 1970s and 80s, both at CIAT and in national programs, have now retired or will soon do so, and that a whole new generation of cassava researchers are currently being hired to take their place.As cassava is now becoming a very important, and mostly industrial, crop in Asia, there are many new opportunities, but also a host of new problems and challenges. These include the appearance in Asia of new cassava diseases and pests; the decreasing availability and increasing cost of rural labor, resulting in the need for partial or complete mechanization of cassava production; the rapidly increasing demand for cassava roots for production of food, feed and fuel, and the unavailability in many countries of new land for any expansion of cassava area, thus requiring a rapid increase in cassava yields to increase supplies. This requires a renewed focus on cassava research for the development of new higher-yielding varieties and more sustainable production practices.While many cassava researchers in national programs in Asia received individual or group training at CIAT-Colombia during the 1970s and 80s, this training was greatly reduced during the following two decades due to funding limitations. Thus, the objective of the Regional Cassava Training Course in 2008 was to provide a new training opportunity for young scientists in Asian countries, and to hand over the knowledge and experience of the older cassava researchers, mostly from CIAT, to a new generation that will have to face the new challenges. Thus, the course was taught mostly by current or already retired CIAT cassava researchers, while the 60-plus participants of the course included cassava researchers from Cambodia, China, East Timor, India, Indonesia, Lao PDR, Malaysia, Myanmar, the Philippines, Thailand and Vietnam. The training course not only provided knowledge -from physiology and biotechnology to animal feeding and production of fuelethanol -but also an opportunity for people from different institutions and countries to get to know each other, which will greatly facilitate future collaboration.Course participants returned home with a CD containing the PowerPoint presentations of the course. However, it was felt that a more comprehensive review of all the topics covered was warranted, as this would provide more in-depth knowledge for those working in the various specialized fields. Most of this information is available in many refereed journals, in workshop proceedings and old CIAT annual reports, but many of these are now out of print or otherwise difficult to obtain. Thus, the Cas...
