In this paper, we consider the following coupled elliptic system
 $$$\left\{ \begin{array}{ll} -\Delta u+\lambda_1 u = \mu_1 u^3+\beta uv^2-\gamma v &\text{in } \mathbb{R}^N, \\ -\Delta v+\lambda_2 v = \mu_2 v^3+\beta vu^2-\gamma u &\text{in } \mathbb{R}^N, \\ u(x), v(x)\rightarrow 0 \text{ as } \vert x\vert\rightarrow+\infty. \end{array} \right.\nonumber$$$
Under symmetric assumptions
 $\lambda_1 = \lambda_2, \mu_1 = \mu_2$
, we determine the number of
 $\gamma$
-bifurcations for each
 $\beta\in(-1, +\infty)$
, and study the behavior of global
 $\gamma$
-bifurcation branches in
 $[-1, 0]\times H_r^1\left( \mathbb{R} ^N\right)\times H_r^1\left( \mathbb{R} ^N\right)$
. Moreover, several results for
 $\gamma = 0$
, such as priori bounds, are of independent interests, which are improvements of corresponding theorems in [6] and [35].
