Abstract

In this study 414 varieties/germplasm accessions originating from Pulses Research Institute, AARI, Faisalabad, NIAB, Faisalabad, BARI, Chakwal, AZRI, Bhakkar, NARC, Islamabad and ICARDA, Syria were evaluated for fusarium will. These were planted in a wilt sick plot developed at Pulses Research Institute, Faisalabad during the year 2002-03 and 2003-04. Each entry was sown in a single 3 meter long and 30 cm apart rows. A highly susceptible variety 97108 was planted as spreader after every two lest entries to map the uniformity of infestation in the field. Disease observations were recorded from seedling stage to maturity at 15 days interval and varieties were evaluated following international 1-9 scale. Early wilt was counted two months after sowing and late will during last week of April. Thirty-five test lines were found resistant, 208 intermediate, 77 susceptible and 84 were highly susceptible. Six promising lines (02007, 02024, 02065, 02095, 03002, 03020) of Pulses Research Institute, Faisalabad and four of AZRI, Bhakkar ($8K007, ICCV97038, ICCV37 and 2KCCO05) were found resistant. Similarly, six lines {9102-13, 9106-37, 9118-30, 9129-2, 3154-18 and 9158-34} originated from ICARDA and six (98CC-036K, 99CC-039K, 2KCCO03, 2KCCO0¢, 2KCCO08 and 2KCC108) of BARI, Chakwal were found intermediate resistant to chickpea wilt. Among 94 highly susceptible germplasm accessions. the lines included 02031, 02053, 02679, 03022, 03031, 03054, 9120-5 (PRI), 2KCC-002, 2KCC-003, 2KCC-007, 2KCC-009 (BARI), Fip97-59C, Flip97-85C, NCSY95-0030, NCSG5-K4, NCS95-0201 and NCS98-K4A (ICARDA). The commercial varieties C-44, CM-72, CM-88, Bittal-98, Paidar-91, Winhar-2000 and Punjab-2000 were aviso found intermediate resistant whereas Karak-98, Balkassar-2000 susceptible and CM-98, Punjab-91 and Noor-81 highly susceptible to fusarium wilt. The varieties 97012 and ILC1929 sown s spreader after every two test entries were rated as highly susceptible in all cases
