Restriction fragment length polymorphism (RFLP) analysis and multicolor genomic in situ hybridization (GISH) are useful tools to precisely characterize genetic stocks derived from crosses of wheat (Triticum aestivum) with Thinopyrum intermedium and Thinopyrum elongatum. The wheat × Th. intermedium derived stocks designated Z1, Z2, Z3, Z4, Z5, and Z6 were initially screened by multicolor GISH using Aegilops speltoides genomic DNA for blocking and various combinations of genomic DNA from Th. intermedium, Triticum urartu, and Aegilops tauschii for probes. The probing (GISH) results indicated that lines Z1 and Z3 were alien disomic addition lines with chromosome numbers of 2n = 44. Z2 was a substitution line in which chromosome 2D was substituted by a pair of Th. intermedium chromosomes; this was confirmed by RFLP and muticolour GISH. Z4 (2n = 44) contained two pairs of wheat – Th. intermedium translocated chromosomes; one pair involved A-genome chromosomes, the other involved D- and A-genome chromosomes. Z5 (2n = 44) contained one pair of wheat – Th. intermedium translocated chromosomes involving the D- and A-genome chromosomes of wheat. Z6 (2n = 44) contained one pair of chromosomes derived from Th. intermedium plus another pair of translocated chromosomes involving B-genome chromosomes of wheat. Line Z2 was of special interest because it has some resistance to infection by Fusarium graminearum.Key words: wheat, Thinopyrum intermedium, addition, substitution, and translocation lines, GISH, multicolor GISH, RFLP.

Collard (Brassica oleracea L. var. acephala) is an important vegetable the southeastern U. S. There are few (about 10) commercial cultivars, half being open-pollinating (OP) lines, the remainder more recent F1 hybrids. There is a potential untapped B. oleracea germplasm pool in the form of collard landraces perpetuated by southeastern gardeners and farmers. To determine the amount of genetic variation among cultivars and also whether landraces represent unique genotypes, ten cultivars and eight lines or landraces were evaluated using RAPD analysis. Decamer primers were used to amplify total genomic DNA and to differentiate collard lines and other B. oleracea crop cultivars. Additionally, individuals of an OP collard cultivar and a land-race were analyzed to evaluate intra-line variation. Virtually all primers detected polymorphic bands among lines although some identified considerably more variants. Intra-line analysis indicated that OP lines are genetically broad-based populations. Many unique RAPD markers were identified in landraces indicating that the lines represent unique genotypes and that further line collection is warranted.

The genetic variability of 40 accessions of_C. arabica was evaluated using a combination of the random amplified polymorphic DNA (RAPD) technique and restriction digestion of genomic DNA. The genetic variability and the relatedness among all accessions were initially evaluated using 195 RAPD primers which revealed a very low level of genetic variation. To improve the efficiency in the detection of polymorphism, the genomic DNA of all accessions were submitted to digestion with restriction endonucleases prior to PCR amplification. A total of 24 primers combined with restriction digestion of DNA rendered 318 bands, of which 266 (83.65%) were polymorphic. The associations among genotypes were estimated using UPGMA-clustering analysis. The accessions were properly clustered according to pedigree and agronomic features. The ability to distinguish among coffee accessions was greater for RAPD plus restriction digestion than for RAPD alone, providing evidences that the combination of the techniques was very efficient for the estimation of genetic relationship among_C. arabica genotypes.
