Journal of Plant Registrations, Vol. 1, No. 2, September 2007 145 Seven chickpea (Cicer arietinum L.) breeding lines, FLIP 2005-1C (Reg. No. GP-264, PI 645455), FLIP 2005-2C (Reg. No. GP-265, PI 645456), FLIP 2005-3C (Reg. No. GP-266, PI 645457), FLIP 2005-4C (Reg. No. GP-267, PI 645458), FLIP 2005-5C (Reg. No. GP-268, PI 645459), FLIP 2005-6C (Reg. No. GP-269, PI 645460), and FLIP 20057C (Reg. No. GP-270, PI 645461) resistant to chickpea leaf miner were developed and released by the International Center for Agricultural Research in the Dry Areas (ICARDA), Syria, in August 2006 for distribution to chickpea researchers for use in breeding programs. Chickpea leaf miner (Liriomyza cicerina Rondani) is an important pest and is widely distributed in west Asia and north Africa, which often causes economic damage to chickpea (Weigand and Tahhan, 1990; Khoja, 2006). Although effective insecticides for the control of leaf miner are available, they are uneconomical and unfriendly, thus rarely used. The use of host plant resistance is the best control option for leaf miner. Evaluation of a large number of chickpea germplasm accessions at ICARDA resulted in the identifi cation of few chickpea cultivars resistant to this pest (Singh and Weigand, 1996). These cultivars were either small seeded or have poor agronomic performance. Because of the high fl uctuation of the leaf miner populations from year to year, it was diffi cult to establish a breeding program for leaf miner resistance. However, by delaying planting for 3 to 4 wk in the spring, we observed that the leaf miner infestation was high enough to discriminate regularly between susceptible and resistant plants. Thus, we initiated a breeding program for leaf miner resistance using the modifi ed screening methodology that included sowing the crop in the late spring (second half of March), irrigating as necessary for Registration of Seven Improved Chickpea Breeding Lines Resistant to Leaf Miner
