    Notes: Amplified fragment length polymorphism (AFLP) analysis was used to evaluate the genetic variation among cultivated chickpea and wild Cicer relatives. In total, 214 marker loci were assessed, of which 211 were polymorphic (98.6%) across the 95 accessions that represented 17 species of Cicer. The genetic variation within a species was highest in C. pinnatifidum followed by C. reticulatum and lowest in C. macracanthum. Three main species groups were identified by UPGMA clustering using Nei's pair-wise distance calculations. Group I included the cultivated species C. arietinum, C. reticulatum and C. echinospermum. Within this group, C. reticulatum accessions were clustered closest to the C. arietinum cultivars ‘Lasseter’, ‘Kaniva’ and ‘Bumper’, supporting the hypothesis that C. reticulatum is the most probable progenitor of the cultivated species. Cicer bijugum, C. judaicum and C. pinnatifidum were clustered together creating group II. Group III contained all nine perennial species assessed and two annual species C. yamashitae and C. cuneatum. The genetic distance detected between group I and group III (0.13) was equivalent to the genetic distance detected between group I and group II (the primary and annual tertiary species, respectively; 0.14). This indicated that the perennial tertiary species may be as valuable for increasing variation to incorporate novel germplasm in the cultigen as the annual tertiary species.

    Identification of RAPD markers linked to recessive genes conferring siliqua shatter resistance in Brassica rapa (2003)

    Notes: Shattering of siliquae causes significant seed loss in canola (Brassica napus) production worldwide. There is little genetic variation for resistance to shatter in canola and, hence, the trait has been studied in B. rapa. Previous studies have shown two randomly segregating recessive genes to be responsible for shatter resistance. Three random amplified polymorphic DNA markers were identified as being linked to shatter resistance using bulked segregant analysis in a F3B. rapa population. The population was derived from a cross between a shatter-susceptible Canadian cultivar and a shatter-resistant Indian line. Of the three markers, RAC-3900 and RX-71000 were linked to recessive sh1 and sh2 alleles, and SAC-201300 was linked to both dominant Sh1 and Sh2 alleles. The common marker for the dominant wild-type allele for the two loci was explained to have resulted from duplication of an original locus and the associated markers through chromosome duplication and rearrangements in the process of evolution of the modern B. rapa from its progenitor that had a lower number of chromosomes. Segregation data from double heterozygous F3 families, although limited, indicated the markers were not linked to each other and provided further evidence for the duplication hypothesis.

    Inheritance of resistance to anthracnose caused by Colletotrichum capsici in Capsicum (2005)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Inheritance of resistance to anthracnose caused by Colletotrichum capsici (Syd.) Butler & Bisby was studied in interspecific Capsicum populations derived from a cross between a Thai elite cultivar Capsicum annuum L.‘Bangchang’ and a resistant line C. chinense Jacq.‘PBC932′. The resistance was assessed by measuring lesion area per fruit area (LFA) on detached chili fruits, using a laboratory-based injection inoculation. Nil symptoms resembling the resistant parent ‘PBC932’ were also identified in the progeny F2 and BC1 populations. Segregation of resistance (nil LFA) and susceptibility in the F2 fitted a 1: 3 Mendelian ratio, indicating that resistance was responsible by a single recessive gene. The segregation of the trait in the testcrosses in both BC1s also confirmed the 1: 3 gene segregating model as found in the F2.

    Sensitivity of random amplified polymorphic DNA analysis to detect genetic change in sugarcane during tissue culture (1995)

    Notes: Abstract Random amplified polymorphic DNA (RAPD) analysis using 10-mer oligonucleotide primers efficiently differentiated sugarcane cultivars and proved suitable for detecting gross genetic change such as that which can occur in sugarcane subjected to prolonged tissue culture, for example in protoplast-derived callus. However, RAPD analysis was not sufficiently sensitive to detect smaller genetic changes that occur during sugarcane genetic transformation. The length of DNA scored for polymorphism per primer averaged 13.2 kb, or 0.0001% of the typical sugarcane genome size of 1.2 × 107 kb (2C). RAPD analysis of sugarcane plants regenerated from embryogenic callus revealed very few polymorphisms, indicating that gross genetic change is infrequent during this tissue culture procedure, although epigenetic effects result in transient morphological changes in regenerated plants. More sensitive variations on the RAPD technique may increase the practicality of DNA-based screening of regenerated plant lines to reveal somaclonal variants.

    Genetics of resistance to ascochyta blight (Ascochyta lentis) of lentil and the identification of closely linked RAPD markers (1999)

    Notes: Abstract  Foliar resistance to Ascochyta lentis is controlled at a single major locus by a dominant gene (AbR 1 ) in the lentil accession ILL5588 (cv ‘Northfield’). Flanking RAPD markers that are closely linked to the resistance locus in coupling phase were identified by bulked segregant analysis. Out of 261 decanucleotide primers screened 7 produced a polymorphic marker that segregated with the resistance locus, and all markers were found to exist within a single linkage group. Five of the seven RAPD markers were within 30 cM of the resistance locus. Log likelihood analysis for detecting QTL associated with the foliar resistance revealed that a single narrow peak accounted for almost 90% of the variance of resistance between the bulks. Preliminary mapping in an F3 population revealed that the closest flanking markers were approximately 6 and 14 centiMorgans (cM) away from the resistance locus. These markers should be useful for the discrimination of resistant germplasm through marker-assisted selection in future breeding programmes and represent the first essential step towards the map-based cloning of this resistance gene.
