Abstract
This investigation was carried out on forty one commercial rice varieties and promising lines to evaluate their relative resistance and select some against rice leaf miner; Hydrellia prostemalis Deem., and role of some factors in this resistance . It proved that : - Entries ; Giza 172, LR 25571-31-1, GZ 3766-38-1-2, GZ 4127- 2-1-3„G2 4255-6-1 and GZ 4294-10-2 were relatively the most resistant (least preferred) entries to rice leaf miner infestation showing 0.13,0.14,0.15,0.16 and 0.19 % , respectively, as damaged leaf area (DLA%) which is the most accurate parameter for the miner damage. On the other hand, Giza 180, Giza 181, GZ 4255-6-3, Giza 171, Giza 175, GZ 4386-34-3 and Yabani 15 were relatively the most susceptible (Most preferred) entries showing 0.41, 0.47, 0.51, 0.52, 0.56, 0.58 and 0.62%, respectively. As based on the percentage of the infested leaves (IL %), as the most common and easiest parameter, GZ 4127-2-1-3, GZ4294-9-4 AND GZ 4255-9-1 entries were relatively the most resistant (least preferred) showing 18, 18.6 and 19.1%, respectively, as compared to Giza 171 of 33.6%. As based on the number of mines/leaf, GZ 3766-38-1-1 and GZ 4249-4-9 entries were the most resistant showing 0.29 and 0.33, while Giza 171 of 1.09 was the most susceptible one. Using the damaged area/leaf as a parameter, GZ 4294-10-2 was the most resistant entry showing 2.63 mm compared to Yabani 15 of 9.63 mm/leaf When overall resistance or susceptibility indices (ORSI); as a collective measure for all used parameters was calculated, GZ 4127-2-13, Todorpkiwase, GZ 4255.6-1, GZ 3766-38-1-1 and GZ 4294-9-4 were highly resistant entries as compared with Giza 176 the most common variety in Egypt.
