Diallel analysis of salinity tolerance at germination and the early seedling stage in bread wheat (Triticum aestivum)

Salt stress is one of the most crucial abiotic factors and affects about 20 % world's irrigated land. The present study was conducted to evaluate combining effects salinity response at early seedling stage, (root length, coleoptile shoot germination rate vigour) using four parents their 4 x full-diallel crosses bread wheat. Parents F2 hybrids were assessed in laboratory under induced by sodium chloride (NaCl) with two treatments (0 control, 100 mMol). General (GCA) ability mean squares highly significant for all traits studied. GCA: SCA (specific ability) greater than unit studied additive genes indicated a higher contribution non-additive inheritance these characters. GCA showed that 84CZT04 desirable general combiner root length condition. Estimates demonstrated 1× 3 × 1could be regarded as cross-combination both conditions.
