摘要：
Evaluation of 397 common bean accessions of diverse origin revealed the presence of effective sources of resistance against bean common mosaic potyvirus strains prevalent in Himachal Pradesh, a north-western Himalayan state of India. 21 accessions viz., KR 7, KR 225, KR 295, KRC 4, KRC 7, KRC 11, KRC 12, KRC 13, KRC 16, KRC 22, Amanda, Black Turtle Soup, Contender, Hans, Great Northern UI 123, Improved Tender Green 40031, Jubila, Kentucky wonder, Monroe, Premier and Sanilac, were found resistant to NL-1n and NL-7n strains. Some of the genotypes showed strain specific resistance. Pattern of inheritance studied in Hans, Contender, KRC 4 and KRC 22 of Indian origin against strain NL-1n revealed that single dominant gene governed the resistance in Hans and Contender whereas single recessive gene determined the resistance in KRC 22 and KRC 4. SCAR marker SW13690 amplified a product of 690 bp in Hans and Contender, confirmed the presence of I gene in these cultivars. The implications of above genes in breeding for programme for BCMV resistance are discussed.
