用来测定自交系配合力的品种、自交系、单交种等,统称为测验种。这种杂交称为测验杂交,简称测交,其杂种一代称为测交种。目前进行晚代测交时广泛采用以若干个优良自交系作测验种,同时测定新自交系的一般配合力和特殊配合力,使配合力测定与杂交组合选配相结合,这样,在测交过程中发现的优 Inbred lines used to determine the combining ability of varieties, inbred lines, single cross-species, collectively referred to as test species. This hybrid known as the test hybridization, referred to as test cross, the hybrid generation called test cross species. At present, it is widely used to test several elite inbred lines at the time of dating in the late generation, and to determine the general combining ability and the special combining ability of the new inbred lines at the same time, so as to combine the combining ability determination with the hybrid combination matching. Test found in the process of excellence
