| Abstract: |
| A variety comparing test was conducted for the BADH (betaine aldehyde dehyrogenase) transgenic rice lines (51-15, 51-22, 52-7 and 52-3), the receptor rice (Zhonghua 8) and the local upland rice cultivars Baizhenzhu (ck1) and Kaixi 7 (ck2) under the condition of dry farming. The comprehensive analysis on 21 agronomical characters of the trial materials showed that the BADH transgenic rice lines were significantly superior to the receptor under dry farming management. According to their correlated degree to the reference variety, the 7 trial materials could be put in sequence as: 51-22>51-15>Baizhenzhu>52-7>52-3>Kaixi 7>Zhonghua 8. Using the method of cluster analysis, the trial materials were divided into three categories, in which the first included 52-7, 51-22, 51-15 and Baizhenzhu, the second included 52-3 and Kaixi 7, and the third included only Zhonghua 8. The transqenic rice lines 51-22, 51-15 and 51-7 were characterized with fine agronomical traits, and were suitable to be grown under dry farming. |
