Session 4 Conventional and Novel Methodologies for Plant Improvement ABSTRACT SSR-(single sequence repeat), and RAPD (randomly amplified polymorphic DNA) primer generated DNA fingerprints were used to distinguish a new genotype of quackgrass from its original type of Agropyron repenes L. Beauv. (= Elytrigia repens). Products of polymerase chain reactions (PCR) were separated by agarose (AGE) an...

Members of the scaphidiine tribe Scaphisomatini collected recently in Tianmushan Biosphere Reserve (Zhejiang) and Wuyishan National Nature (part Reserve, Fujian), China, are studied. Two species, Scaphisoma krali Löbl, sp. nov. sekerkai nov., described from Wuyishan. Baeocera franzi (Löbl, 1973) mutator 2000 recorded for first time Zhejiang province, binhanum (Pic, 1922) Scaphoxium intermedium ...

During parasitological surveys in the Okavango Delta and Panhandle in Botswana, two species of climbing perches belonging to the family Anabantidae were investigated for ectoparasites. The fishes were the blackspot climbing perch, Microctenopoma intermedium (Pellegrin) and the manyspined climbing perch, Ctenopoma multispine Peters. Five trichodinid species were found from the skin, fins and gil...

Cluster analysis followed by stepwise discriminant analysis was used to delineate ecological stages on a mixed grass prairie in western South Dakota. Forty-seven variables were analyzed for 48 sites ranging from potential vegetation to early seral stages. A cover-frequency index for western wheatgrass (Agropyron smithii), blue grama (Bouteloua gracilis), and buffalograss (Buchloe dactyloides) w...
