| 自2014 年第2 季度开始，随着H7N9 事件逐渐消退，广东肉鸡产业逐步回暖，但完全恢复尚待时日。2014 年广东省肉鸡出栏量、年末存栏量和年饲养量大幅下跌，全年出栏量为6.51 亿只，同比减少近10%；年末存栏量为2.31 亿只，同比上升2.21%；年饲养量8.82 亿只，同比下降7.06%。分析2014—2015 年广东肉鸡产业产品的价格变化，预测2016 年鸡肉产品价格，并对今后广东肉鸡业发展提出对策建议。 |
| 英文摘要: |
| The combination of anther culture techniques and traditional sterile lines breeding can effectively speed up the improvement of photo-thermosensitive genic male sterile（PTGMS） lines. To screen for the optimal culture medium for the two-line male sterile line， Y58S，we studied the effects of 10 different culture mediums on the F2 generation of different cross combination between Y58S and selected male parents. The results showed that medium E（NMB+2 mg/L 2，4-D +2 mg/L NAA+1 mg/L KT+0.5 g/L Pro+0.5 g/L Gln+0.5 g/L CH+25 g/L sugar+25 g/L Maltose+10 g/L Agar）was more effective for anther culture of PTGMS lines. And introducing japonica rice by cross breeding improved anther culture ability of PTGMS lines，indicating that genetype played an important role in rice anther culture. The examination on traits in field of descendants displayed that most of the plants were diploid， some were haploid and tetraploid， and no non-integer ploidy，and a new PTGMS lines was screened. |
