But significant differences were found in coefficient of variation and broad-sense heritability (H2) of the three characters: CV and H2 of self-pollinated fruiting rate were both greatest, with the variation mainly resulted from inheritance, and high inheritance potential; H2 of fertile flower rate was the least and its variation was less from inheritance; CV of average fruit weight was the least and its inheritance potential is small. Thirdly, the ratios of sweet to bitter kernel of F1 progenies in positive and reverse crosses between Katy and Taianshuixing were 18∶16 and 13∶12, and were both in agreement with a 1∶1 segregation by χ2 test, which demonstrated that the bitter kernel character of Katy was heterozygous.

但3个性状的变异系数和广义遗传力(H2)均差异很大，其中自交坐果率的变异系数(101.5%～139.1%)和广义遗传力(87.1%～91.4%)均较大，表明变异主要来自遗传效应，并且自交坐果率的遗传潜能大；有效花比率的广义遗传力最小(36.8%～49.1%)，表明其遗传效应较小；平均单果重的变异系数最小(24.0%～29.7%)，说明平均单果重的遗传潜能小；（3）凯特与泰安水杏正反交的杂种一代甜仁与苦仁的比例分别为18∶16和13∶12，经χ2检验符合1∶1的分离比例，证明控制凯特杏甜仁与苦仁这对性状的基因位点是杂合的。

Lines transformed by particle bombardment have been discussed. The selectable marker bar gene cassette that integrated with the rice genome had multiple copies and showed complex segregation behaviors including the presence of 'false homozygotes', with abnormal segregation ratios ranging from 35:1 to 144:1 (Basta-resistant: sensitive plants) in their progenies. In five out of ten original transgenic lines, bar gene can be stably transmitted as a dominant gene to self-pollinated T2 progeny.
