不同组合间的SCA效应与超亲优势呈正相关关系。
The SCA effects of different crosses were positively correlated with super parent heterosis.
衣分的群体平均优势在两代均为正向，群体超亲优势均为负向且达到1%显著水平；
The mid-parent value for lint percentage in the two generations are positive, the better-parent value are negative to 1% significance level;
因此在耐热育种中单纯利用杂交优势试图获得超亲优势来显著提高耐热性是不现实的，而应该注重耐热亲本的定向选择。
So it is not practical to improve the heat resistance significantly in breeding by heterosis, but it is supposed to select the heat tolerant parent in breeding.
