2个环境条件下花生产量性状的遗传分析

Abstract

Abstract: The number, of pod branches （NPB）, the number of pods per plant（NPP） and lO0-pod weight（100PW） of peanut are important to yield traits. To offer uset＇ul intormation tor breeding cuhivars with high yield, we investigated NPB, NPP and 100PW of Yuanza 9102（P1）,Wanhua No.4（P2） and 133（Hetei,E1） F2 lines and 151（Guzhen,E2） F2 lines derived from the cross P1 xP2. Three traits were analyzed with mixed major gene and polygene inheritance model. Genetic analysis revealed that the NPB were controlled by one pairs of additive xdominance major genes in two environments. NPP were controlled by two pairs of additive xdominance major genes in Hetei, while NPP were controlled by one pairs of additive x dominance major genes in Guzhen.100PW was controlled by two pairs of equidominant major genes in two environments.
