Thirty-four isolates of Fusarium oxysporum, obtained in China from cucumber plants showing either Fusarium wilt (F. oxysporum f. sp. cucumerinum) or root and stem rot (F. oxysporum f. sp. radicis-cucumerinum) symptoms, were characterized by pathogenicity, vegetative compatibility, and random amplified polymorphic DNA (RAPD). Of these, 23 isolates were identified by pathogenicity as F. oxysporum f. sp. cucumerinum, and one as F. oxysporum f. sp. radicis-cucumerinum, while 10 isolates were avirulent on cucumber, melon, sponge gourd, and pumpkin. The Chinese isolates of F. oxysporum f. sp. cucumerinum were assigned to RAPD groups III and XXI and to vegetative compatibility group (VCG) 0183, four new VCGs, 0184 to 0187, and a single-member VCG included in the artificial VCG 018-. The Chinese isolate of F. oxysporum f. sp. radicis-cucumerinum was assigned to RAPD group I and bridging VCG 0260/0261. The occurrence of F. oxysporum f. sp. radicis-cucumerinum on cucumber is reported for the first time in China.

<p>The New Zealand pioneer, like the North American frontiersman, has become to many New Zealanders a romanticized symbol rather than a real person struggling to adapt to a strange and often frightening environment. 'As ye sow so shall ye reap' was for the pioneer farmer an injunction to be taken literally. After exhausting his resources in buying his small-holding the pioneer farmer 'would start on foot and alone...with a heavy swag of tools etc, on his back, to which, on passing the last older settler, would be added the additional burden of a kit of seed potatoes and some rations. With these he would camp down on his future lowly home and would work hard, for long hours on very scanty fare...to hurry in a patch of potatoes, and to make a pig-proof fence round it. He would then beat a retreat to the more settled districts, where he would seek employment until his little crop of potatoes was grown when he would return with a heavier load of rations...and this time he would be able to put in a larger crop and to build a whare, so that the next season he might have the joy of conveying his family to the scene of their future expectations. But it was hand work, and there were many privations to undergo for the first few years....'</p>
