Abstract
Two Drechslera spp., D. teres (conidial state of Pyrenophora teres) and D. sorokiniana (conidial state of Cochliobolus sativus), were found on New Zealand certified barley seed produced during the 1974–75 and 1975–76 seasons; 74% of barley lines tested were infected with D. teres and 15.5% with D. sorokiniana. Seed lines from the North Island carried the most infection, 100% being infected with D. teres and 40% with D. sorokiniana, and in South Island lines, 59% were infected with D. teres and 2% with D. sorokiniana. The mean percentage infection per seed line averaged 21% for D. teres and 2% for D. sorokiniana (44% D. teres and 5% D. sorokiniana in the North Island; 8% D. teres and 0.3% D. sorokiniana in the South Island). No differences in cultivar susceptibility were detected. D. graminea (conidial state of P. graminea) was not detected.This publication has 7 references indexed in Scilit:
