| Abstract: |
| The agronomic and yield characters of nine strains of Gossypium barbadense L., in which Bt gene was detected by PCR, were studied. The results showed that agronomic characters and yield characters were impacted to different extent.(1) When K222 was the recipient, the difference in plant height, start high, initial segment number, number of effective branches, boll number and number of effective bolls got to excellent significant level (P＜0.01）. When XH25 and XH30 were recipients, there was no difference between transgenic and non-transgenic; (2) The difference in plant height, start high, initial segment number and boll number between the nine strains got to excellent significant level （P＜0.01）. Difference in number of effective branches and number of effective boll arrived at significant level （P＜0.05）; (3) There was no significant difference between transgenic and non-transgenic in yield characters; (4) Plant height, start high, initial segment number, boll stem number, number of effective branches, boll number and number of effective boll were significantly related to yield; (5) The difference between two years (2014 and 2015) and two areas(the northern of Xinjiang and the southern of Xinjiang) got to significant level in agronomic characters and yield characters. |
