To evaluate, phonological traits ( days to emergence, to tillering, stem, heading, maturity), and in final grain yield fourty eight bread wheat doubled haploid lines were compared in two places Ahwaz and eighteen lines and two local check in ranomaized complete design in two sowing date mid Nov. and early Jan. for simulating terminal heat stress for wheat growth stages( heading and grain filling)) at cropping season 2006- 07.Results showed that total mean grain yield of local varieties( Vee/Nac, Chamran) were 3903 and 4258 kg/ha respectively. Lines No. 4, 11, 15, 20, 27, 44, 56 and 57 with grain yield 4728, 4150, 4448, 4099, 4020, 4541, 4363 and 4402 kg/ha respectively, were superior 10 percentage compared with local varieties. Based on combine analysis in desirable and undesirable in three area and total combine analysis (three area and two conditions) in replicate trail and Heat Susceptibility Index (H S I), total grain yield and grain yield in undesirable condition ( mean of three area) selected lines No. 3, 6, 7, 9, 19 and 20.
