| Inbreeding depression is an important Genetic phenomenon, selfing is an important way of Cultivating fine crop varieties, the principle of self-incompatibility have very important value in improving Economic benefits of Economic plants, as the inbreeding depression and heterosis is a opposite genetic phenomena, the research of inbreeding depression have important value for the research of heterosis.Studying on the selfing of diploid Eremurus inderiensisã€diploid Eremurus anisopterusã€Tetraploid Eremurus inderiensis, The main results are summarized as follows:1. According to Statistical results of the diploid Eremurus inderiensisã€diploid Eremurus anisopterus and their offspring’s height, the decrease of their selfing offsprings’ height reached a very significant level;2. According to Statistical results of the Tetraploid Eremurus inderiensis and their selfing Progeny’s height, the decrease of their offsprings’ height reached a significant level,but the reduction of it’s Progeny’s height is not than The diploid Eremurus inderiensis’ Progeny.3. The heterosis is a relative concept, and the theory has great value in is a relative concept, and the inbreeding depression and inbreeding depression and and the inbreeding depression and inbreeding depression and.4. Proving the new theory of Inbreeding depression by the research. |
