轮回选择是玉米育种程序中的组成部分,而且在其它作物中也日趋重要。Sprague等(1977)、Gardner(1978)、Hallauer等(1978)、Hallauer(1984)对不同的轮回选择方法及应用已有过讨论。用于群体内改良的轮回选择法包括混合选择、S_1、S_5、全同胞群体(FS)、修改FS(MFS)、
Reincarnation is an integral part of the corn breeding program and is increasingly important in other crops. Sprague et al. (1977), Gardner (1978), Hallauer et al. (1978) and Hallauer (1984) have discussed different recurrent selection methods and applications. Recycling selection methods for population improvement include mixed selection, S_1, S_5, whole sib population (FS), modified FS (MFS)
