Studies on Seed Transmission of Urdbean Leaf Crinkle Virus on Vigna mungoChRavinder ReddyauthorV ATonapiauthorSVaranavasiappanauthorS SNaviauthorRJayarajanauthorSeed transmission of Urdbean leaf crinkle virus was maximum in pods located at the base of the plant rather than pods produced subsequently. There was no relationship between extent of seed transmission and pod position on the plant while considering the individual plants showing infected leaves. The growing-on-test can be effectively ascertained for testing seed-borne infection. The virus was detected only in embryo and cotyledons. Seed lots showing 2.0 to 3.6 per cent seed borne infection recorded 45.2 to 86.5 per cent disease incidence in the post flowering stage in field conditions. The produce from this field yielded 3.6 to 8.6 per cent virus-infected seeds.Agriculture-Farming, Production, Technology, Economics2005Plant Protection Association of IndiaArticle
