Potential variability of trans-lysozyme gene rice under ecological conditions of Yunnan
云南生态条件下基因枪法转溶菌酶基因水稻潜在变异性

With trans-lysozyme gene rice line D2-1-2 and its restorer Zhonghua No.9 as test materials, this paper studied their agronomic characters and grain qualities under two ecological conditions of Yunnan. The results showed that there were no significant differences in the agronomic characters between D2-1-2 and Zhonghua No.9, but the seed setting rate and plant height of D2-1-2 were significantly lower, while the protein, amino acid, and mineral element (Ca, Fe and Zn in particular) contents in its crude grain were higher than those of Zhonghua No. 9. It was considered that there could be some potential genetic variances in transgenic plant, and the possibly induced environment risk should be evaluated in multi-plots for several years.
