“…These have been used to develop physical maps of various wheat chromosomes at the cytogenetic level (Gill et al 1996;Gill and Gill 1994), but can also be used effectively in comparative mapping, by mapping heterologous probes into various deletion regions. Thus, one can compare the location of different markers from different species in the same deletion bin without the need to look for polymorphism (Sarma et al 1998).…”

The wheat homoeologous Group 5 chromosomes were characterized physically in terms of rice linkage blocks using a deletion mapping approach. All three chromosomes, 5A, 5B, and 5D, were shown to have a similar structure, apart from the 4A-5A translocation on the distal end of chromosome arm 5AL. The physical mapping of rice markers on the deletion lines revealed that the whole of rice chromosome 9 is syntenous to a large block, proximal to the centromere, on the long arm. Likewise, a small segment of the distal end of the long arm showed conserved synteny with the distal one-third end of the long arm of rice chromosome 3. In between those conserved regions, there is a region on the long arm of the Group 5 chromosomes which shows broken synteny. The proximal part of the short arms of the Group 5 chromosomes showed conserved synteny with a segment of the short arm of rice chromosome 11 and the distal ends showed conserved synteny with a segment of rice chromosome 12. The physical locations of flowering time genes (Vrn and earliness per se) and the gene for grain hardness (Ha) on the Group 5 chromosomes were determined. These results indicate that comparative mapping using the deletion mapping approach is useful in the study of genome relationships, the physical location of genes, and can determine the appropriate gene cloning strategy.

“…The location of Vrn-A1 was predicted by Gill et al (1996) from hybridization of mapped RFLP markers to the deletion lines, and it was then mapped physically on chromosome 5AL, flanked by deletion breakpoints 0.68 and 0.78, by Sarma et al (1998). Group C deletion breakpoints are beyond 0.78 (Fig.…”

“…The existence of a locus controlling flowering time (named eps-5A), suspected to be homoeologous to the earliness per se locus eps-5H of barley, was predicted by Snape and Laurie (1998), based on comparative mapping analysis. Sarma et al (1998) physically mapped markers associated with this eps-5H locus onto the same deletion bin on chromosome 5A of wheat. Earliness per se genes have been less studied and are apparently not responsive to environment, but determine the basic duration of phases until flowering.…”

The aim of this investigation was to test the developmental patterns of deletion lines, generated for chromosome arms 5AL and 5DL in the variety ‘Chinese Spring’ (CS) under vernalized and non‐vernalized treatments. Plants were grown in controlled conditions under saturating daylength. Time to heading and the duration of particular phases before flowering were recorded, and leaf and spikelet production rates and numbers were analysed. The lines lacking Vrn‐A1 and Vrn‐D1 were delayed in time to heading under non‐vernalized conditions, because of the lengthening of the emergence to floral initiation phase (EM‐FI) and the terminal spikelet to heading phase (TS‐H). Differences in final leaf numbers corresponded to longer durations of the EM‐FI phase. The absence of Vrn‐A1 and Vrn‐D1 apparently decreased the number of spikelets by a lower primordium production rate, even though the duration of the FI‐TS phase was longer or equal to CS. The sensitivity to vernalization in lines where the Vrn genes were deleted was much higher.
