With a F2 population between a resistant and a susceptible parent (03036×03748), the linked marker was screened by BSA method and RAPD technology. Two specific bands were found at the 500 bp region using F2-based bulked segregant analysis plants.

以番茄抗叶霉病和感叶霉病亲本组合(03036×03748)的F2分离群体为研究材料，采用BSA法和RAPD技术筛选与抗病基因连锁的分子标记。

Results (1)Relevance rate of behavioral problems in type 1 diabetes group was 20.2%,two fold significantly higher than that in the control group(8.2%)(P=0.000).(2)Logistic analysis showed that risk factors concerned behavioral problems in diabetic children and adolescents included patients lived in rural areas,poor parents' marital relationship,poor parent- child relation,improper cultural ways,poor communication and understandings between family members,uniparental family and poor control of blood glucose.(3)It was found that diabetes was the most significant risk factor affected the occurrence of behavioral problems among all related factors based on the analytic results in both the type 1 diabetes group and the health group.Conclusions (1)Children and adolescents with type 1 diabetes are the high- risk population who are apt to the occurrence of behavioral problems.

结果①行为问题的检出率：糖尿病患儿检出率为20.0%，与健康对照组(8.2%)比较，糖尿病患儿行为问题检出率高于健康对照组P=0.000；②Logistic回归分析显示，与糖尿病患儿行为问题有关的危险因素分别为在农村生活、双亲关系紧张、亲子关系差、缺乏直接感情交流、教育方式不当、对子女了解较少、仅由父母中的一方承担管理子女的责任及血糖控制不良；③将健康对照组与1型糖尿病组综合分析后发现：影响行为问题发生的所有危险因素中，患糖尿病的相对危险度最大。

In addition,the proportion of Typical Abortive pollen and Normal pollen acted as the fertility indexs and typical sterile group or normal fertile group was classified in segregative population according to the pollen fertility of parent or F1 hybrid.

在育性指标的划分上，本研究确定以亲本不育系及与恢复系配制的杂种F_1的花粉育性作为划分典型不育株和正常结实株的标准。

The results showed that there were differences among treatments in transformation of high quality gene(Glu\|D 1 5+10) in F 1 grains, and heterozygous type was more frequently appeared in the treatment of irradiation. In the F 2 segregative population, heading date deviated to early\|mature parent in the treatment of reciperocal cross and its combination with irradiation, indicating that cytoplasm and irradiation could promote the heading. In F 3 the expressive frequency of (5+10) gene in the cross was lower than that in reciperocal cross, and irradiation treatment could raise the expressive frequency of(5+10) gene. These results showed varience in different crosses.

结果表明，不同组合处理间F1籽粒优质亚基(Glu D15+1 0 )的转化存在差异，辐射处理的多以杂合型出现。F2 分离群体中，反交及反交结合辐射处理的抽穗期明显倾向于早熟的亲本，细胞质与辐射具有促进抽穗期的作用。F3 植株Glu D15+1 0亚基的表达频率，不论是哪种组合，反交时 5+1 0亚基的表达频率高于正交；无论正交还是反交，辐射处理提高了 5+1 0亚基的表达频率，而且在不同组合间存在差异。
