IDENTIFICATION OF ANTHRACNOSE RESISTANCE IN LENTIL.
RUBAB ALTAF
Abstract
Lentil (Lens culinaris Medikus) anthracnose caused by fungus Colletotrichum lentis Damm is one of the most significant threats to lentil cultivation globally. Lots of information regarding identification of lentil anthracnose resistance has been published all over the world, however no comprehensive data prior to this work was available in Pakistan. Current work encompasses status of available lentil germplasm accessions towards this disease. For this purpose, screening of 31 available lentil accessions were conducted against the known highly virulent Colletotrichum lentis isolate CLK-63 at seedling and flowering stage. Accession Masoor-85 served as check/spreader in the investigation. At seedling stage, most of accessions; 20 (64.51%) were found susceptible (11, 35.48%) to highly susceptible (9, 29.03%) to isolate CLK-63; whereas three (9.67%) moderately resistant and eight (25.80%) resistant to anthracnose. At adult stage, like seedling stage, the maximum accessions 19 (61.29%) were found susceptible to highly susceptible to isolate CLK-63 followed by eight (25.80%) resistant and four (12.90%) moderately resistant to anthracnose. Thus, almost all the accessions responded in the same manner towards isolate CLK-63 at seedling and adult stage. Accessions, specifically Masoor-89, Masoor-86, Masoor-89 bold seeded, Masoor-2004, NARC- 11-1, 08505, Punjab Massor-2009 and Shiraz-96 were found resistant, while accessions 12-308-Lentil, NL-2 and 03501 were found moderately resistant to disease at both the stages of growth. Keywords: Host plant resistance, lentil anthracnose, Colletotrichum lentis.
