For the poor of supersweet maize genetic resources on insect resistance, the insect-resistant varieties is not easy obtained by conventional breeding in the short time.

超甜玉米抗虫种质资源相对贫乏，本身缺少有效的抗虫基因资源，通过常规育种方法在短期内难以获得抗性品种。

In this study, based on establishment of stable and high efficient transfergenic receptor system with supersweet maize callus, the multiple insect-resistant genes were successfully co-transformed into a elite inbred line 1132 and a variety using particle bombardment and overy microinjection, and the transgenic integration, expression and inheritance were studied by means of target character and molecular biology method.

本研究在建立高效稳定基因转化受体系统的基础上，利用基因枪和子房注射两种方法将多个抗虫基因成功转化抗性较差的超甜玉米自交系及其品种，并从分子水平和目标性状上研究外源基因的转入、整合、表达与遗传规律。

Bt gene was successfully transferred into elite supersweet maize hybrid by overy injection in the field, and one transgenic plant ZT11 integrated with Bt gene was obtained.

用子房注射法将Bt基因导入超甜玉米品种粤甜3号，获得了1株整合有Bt基因的转基因植株，定名为ZT11，以发芽成苗的植株计算，基因转化效率达9.09%。

By PCR amplification and southern blot analysis, the extrogenous gene with specific promoter was confirmed to integrate into the supersweet maize genome DNA with single-copy, and transformation frequency could reach as high as 9.09%.

经PCR和Southernblot分析，证明抗虫基因已经整合在超甜玉米基因组中，并且为单拷贝。T1代植株PCR检测结果表明，Bt基因能够在转基因后代中稳定遗传，基因分离符合1∶1的孟德尔遗传分离规律。

The detection of QTLs for these traits, in combination with the observation of transgressive segregants in our population, indicates that favorable alleles can be combined to increase seedling lateral root growth in maize.

对这些性状的QTL检测，在我国人口中海侵分离子的观察相结合，表明良好的等位基因可以结合，增加玉米幼苗侧根生长。

In order to analyze the conservation of maize centromeric satellite DNA and centromeric retrotransposon in the subspecies and relatives of Zea mays, dual fluorescence in situ hybridization was used to detect the existence and distribution of the above two repetitive sequences in Zea mays ssp. mexicana, Z. diploperennis, Z. perennis, Tripsacum dactyloides, Coix lacryma-jobi, and Sorghum bicolor.

为分析玉米着丝粒卫星DNA和着丝粒反转录转座子在玉米种的亚种及近缘种中的保守性，采用双色荧光原位杂交检测了这两种重复序列在墨西哥玉米、二倍体多年生类玉米、多年生类玉米、摩擦禾、薏苡、高粱中的存在和分布。

Nitrogen forms in compound fertilizer affected biomass accumulation of maize too,and the highest dry weight of shoot and root was found in the plants supplied with compound fertilizer containing 100% urea nitrogen in Udic Isohumisols,and mixed nitrate and ammonium in Udic Cambosols.

生长45 d玉米苗的地上和地下部的生物量，在黑土上均以全酰胺态氮的配方最高，地上部干重较其他配方增加10%左右；而在潮土上则以铵态氮与硝态氮配方的效果最好，铵态氮和酰胺态氮混合的配方在2种土壤上均较差。

To study the effects of placement of water and nitrogen on transport and utilization of water and nitrogen in maize root zone. Experimental treatment have fertilizing in the irrigated furrow and unirrigated furrow.
