Persistence of Forage Legumes
Diseases have now been recognized as major constraints to pasture persistence and productivity throughout Australia. Programs such as the National Subterranean Clover Improvement Program have done much to provide a rational basis for the identificati

Five asymmetric hybrid plants were obtained between Medicago sativa (2n = 4x = 32) and Medicago arborea (2n = 4x = 32) through sexual reproduction and the use of a cytoplasmically male sterile M. sativa genotype. Over 2,000 pollinations were made to

Anthracnose, caused by Colletotrichum trifolii, is one of the most serious diseases of lucerne worldwide. The disease is managed through deployment of resistant cultivars, but new pathotypes present a challenge to the successful implementation of thi

Two new crosses involving four races (races 7, 16, 17, and 25) of the soybean root and stem rot pathogen Phytophthora sojae were established (7/16 cross; 17/25 cross). An F2 population derived from each cross was used to determine the genetic basis o

A technique based on the polymerase chain reaction (PCR) for the specific detection of Phytophthora medicaginis was developed using nucleotide sequence information of the ribosomal DNA (rDNA) regions. The complete IGS 2 region between the 5 S gene of

The relationships between isolates of the complex species Phytophthora megasperma from chickpea in Spain and from chickpea and lucerne in Australia were investigated. In the isolates from Spain > 90% of the sporangia had flattened apices, whereas in

The reaction of cowpea lines to naturally occurring Phytophthora vignae in the held was studied in three trials over the period 1987-89 with the aim of identifying and characterizing lines with partial resistance. Seven lines (CPI 84853, CPI 84851, C

Infection of avocado fruit by Colletotrichum gloeosporioides was studied using light and transmission electron microscopy. In unripe fruit C. gloeosporioides produced an appressorium and an infection peg which ceased growth in the cuticle. In field-i

Metarhizium anisopliae isolates from several insect hosts and from various sugar cane growing areas of Queensland, Australia, were examined for genetic diversity using random amplified polymorphic DNA (RAPD) markers. Thirty isolates of M. anisopliae
