(genetics) the tendency of a crossbred organism to have qualities superior to those of either parent

The advantage of these crossbreeding strategies is due the hybrid vigor (heterosis) observed on the hybrid offspring (Hill et al., 1983; Lopez-Villalobos et al., 2000).
Conclusion: Based on the results of present study it was accomplished that flag leaf area, 1000-grain weight and harvest index were the best traits for heterosis in both crosses and these plant parameters might be considered as selection criteria traits in wheat breeding to develop high yielding wheat genotypes.
hybrids suggested the presence of heterosis for all the characters and similar findings were reported by Mirarab and Ahmadikhah (2010).
Standard, mid-parent, and better parent heterosis for grain yield were also calculated for each cross across locations following Hallauer et al.
Studies have shown that the effect of heterosis significantly increases weights throughout the periodic measures of growth performance in pigs [4].
Thus, the heterosis phenomenon should be considered, as well as the predominance of allelic interactions of the non-additive type.
Consequently, testcross populations have been widely used to identify QTLs associated with yield heterosis in rice.
In groundnut, heterosis cannot be exploited for higher production through commercial hybrids due to cleistogamous nature of flower and poor seed recovery during hybridization.
They are important tools to identify possible groups with a higher degree of heterosis in future crosses, and to find sources of resistance to diseases.
Los analisis dialelico s constituyen una herramienta util para estimar los parametros geneticos de los progenitores y sus cruzas, mediante su aptitud combinatoria general (ACG) y aptitud combinatoria especifica (ACE) que permiten definir el metodo de mejoramiento genetico mas adecuado (Wong et al., 2007), y la evaluacion y seleccion de lineas en generaciones tempranas (S3) y/o generaciones avanzadas (S10) que permiten encontrar la mejor combinacion hibrida para explotar la heterosis. Tradicionalmente, en estudios de cruzas de maiz se hace enfasis solo en aptitud combinatoria general y especifica y se ignoran los efectos maternos.
Estimates of heterosis in faba bean were reported to be significantly positive or negative when hybrids were compared to mid or better parents [2, 3, 4, 5, 6,7,8].
