In any hybridization program, recognition of the best combination of two (or more) parental genotypes to maximize variance within related breeding populations, and as a result the chance of recognizing superior transgressive segregants in the segregating populations, are the most critical challenge to plant breeders. Since the combining ability was introduced in 1942, it has been widely adopted...

although inter-variety variability for salt tolerance has been reported in bread wheat plants, little information is available on the genetic control of ion contents and biomass yield under saline conditions. a diallel cross, including reciprocals of two salt tolerant, two moderately tolerant and two sensitive iranian and exotic bread wheat varieties, was analyzed to investigate the inheritance...

Specific language impairment (SLI) has traditionally been characterized as a deficit of structural language (specifically grammar), with relative strengths in pragmatics. In this study, comprehensive assessment of production, comprehension, and metalinguistic judgment of referring expressions revealed that children with SLI have weaknesses in both structural and pragmatic language skills relati...

A study was carried out to assess the combining ability of ten CMS lines with four testers using line x tester method. Biometrical observations were taken for days 50% flowering, plant height, head diameter, maturity, volume weight, hundred seed yield /plant, oil content and yield/plant.  Specific combing variance greater than general all characters which indicated that non-additive gene a...
