SummaryInbreeding species of Lolium have about 40 per cent more nuclear DNA than the outbreeding species. Even so inbreeders may be readily hybridised with outbreeders to produce viable F1's which,… (More)
An attempt to produce a set of addition lines of Aegilops sharonensis to the wheat variety ‘Chinese Spring’ produced only one addition line. This was due to preferential transmission of one… (More)
The technique of in situ hybridisation of cloned ribosomal DNA has been used to establish the numbers of nucleolar organising sites in a range of tetraploid and hexaploid wheats.
DNA sequences cloned from nuclear and mitochondrial chromosomes have been used as hybridisation probes to distinguish different plant genotypes. The probes are hybridised to squashed segments of… (More)
Speciation in eukaryotes is often accompanied by massive changes in nuclear DNA amount resulting from the accumulation or deletion of DNA base sequences within chromosomes. Our evidence shows that,… (More)
The two nucleolus organiser chromosomes of diploid wheat are identified as 1A and 5A by the combination of in situ hybridisation and cytological markers.
SummaryThe meiotic pairing behaviour in hybrids between Aegilops and Secale species has been examined using the technique of in situ hybridisation of tritium labelled RNA copies of cloned DNA… (More)
SummaryTwo different cloned repetitive DNA sequences derived from wheat (Triticum aestivum), one thought to be noncoding and the other coding for ribosomal RNA, were used as probes in in situ… (More)
SummarySecale cereale A series of three experiments was carried out to see if varying sowing density had any differential effect upon the survival of plants with and without B chromosomes. In all… (More)
