Abstract
To investigate the effect of some agronomic and phenologic traits on grain yield and its components in bread wheat genotypes, 18 lines along with 2 controls (Ohadi and Azar2) were studied in complete randomized block design with 4 replications in Maragheh Rainfed Agricultural Research Station in 91-92 crop season. Analysis of variance results showed that all including days to heading, maturity, plant height, 1000 kernel weight, seed yield, spike length, number of grains per spike, number of spikelet per spike, peduncle length, spike weight and flag leaf sheath length were significant except number of plants per square meter that was non-significant. Maximum yield was belong to Azar2 (3048 kgha-1). Lines number 3, 7, 9, 10, 12 and 17 by 2700 kgha-1 were classified as high yielding lines. Lines number 11 and 13 by 2208 and 2209 kgha-1 were classified as the lowest yield. Also, correlation between yield and other characteristics showed that the relationship between plant height and grain yield and flag leaf sheath length was positive and significant.
