In order to study inbreeding depression for yield and some of its associated characters in bread wheat (Triticum aestivum L.em. Thell) over the environments, the present experiment was carried out performing diallel analysis following Griffing (1956) Method II Model I. Ten genetically diverse parents were selected and crossed in half diallel fashion excluding reciprocals. These parents were evaluated along with their 45 F1’s and 45 F2’s in a randomized block design with 3 replications over three environments namely, normal sown (E1), late sown (E2) and very late sown (E3) environments created by using three different dates of sowing. In the present experiment significant inbreeding depression was reported for different traits in all the three environments. Even though, none of the cross displayed significant inbreeding depression in desired direction for all the characters and in all the environments but HD 2967 X DBW 88 was found as desirable cross combination in E3 environment as it showed desirable (significant negative) inbreeding depression for grain yield per plant and some other traits.
