The new maize variety Shaandan 21 (Shaandan 9704) was bred by the male Wu 464 and the female K22 in Maize Institution, Northwest Sci-Tech University of Agriculture and Forestry in 1997. In 2000~2002, the regional test, product test results showed the characteristic of high-stable yield, early mature, disease resistance, good adaptation. The adaptive planting areas were the middle and west parts of Guanzhong plain, Shaanxi province. The optimum desnity range was 45000~50000 seeding / ha. It has been authorized by Crop Authorization Committee of Shaanxi Province in March 2003 and was named Shaandan 21.

Systenatic study was carried out on the physiological change of corn under different waterlogging stress at different growth stages.The rerults indicated that waterlogging caused the imbalance of active oxyen metabolism in plant cells,lead to an extensive membrance—lipid and increase of MDA content , the activity of CAT and chlorophyll content dropped . Under waterlogging stress , there appeared to have a close corrdation between the tissue ability to controol lipid peroxxidation and its ability to retain solutes.

The effects of soaked seeds with different concentrations on the growth of maize seedlings were studied. The results were showed as follows. The elongation of leaf blades and leaf sheaths of the treated plants was inhibited at 3~7-leaf stage, and the higher of the concentration, the stronger of the effect. At the same time, as compared to the control, the plant in uniconazole-treatment showed an appearance of high quality plant with increased specific leaf weight, leaf width and stem thickness as well as root number and root length, the root dry weight, and 40mg.kg-1 was the best.

The early QPM shaandan No.17 was bred by high lysine line Y77(female) and QPM line Y76(male) in special maize office, college of Agriculture, NWSTUAF From 2000 to 2002, the experiment results including regional test, production test in Huanghuihai areas. Showed it had good characteristic of muti-resistance, Lys 0.46%, Pro 11.53%, early mature (it was six days than Nongda 108), Yield as well as normal maize, food and feeding dual purpose. The shaandan No.17 was recommitted to be authorized by National Committee of Crop Variety. It is fit for growing in shaanxi Province and Huanghuihai areas where planting corn in spring, summer. Authors alternatively used backcrossing and selfed crossing as main heterotic pattern of normal maize combination way improved huangaisi×Lancaster line and introduced subtropical germplasm into the parents boarding the germplasm base. Its way was excel and crossing material was new. Shaandan No.17 was the first-rate normal maize, food maize, feeding maize respectively and the second-rate QPM and would be the new released QPM variety instead of main cultivars.

The Paper will discuss influence of liquid chlorine and chlorine dioxide and mixture of both on livingness of Maize root population. The result of experiment show that liquid chlorine in great does poisoned root, and reduced obviously activity of roots. Other disinfectors have no effect on activity of roots, but affect livingness of Maize Root-population. And the right dose of liquid chlorine is 8mg/l，the right dose of chlorine dioxide is 6mg/l, the right dose of mixture is （4＋2）mg/l.

The correlation between Al-tolerance and root activity were studied with inbred lines and part of their F1 generations in maize, by the means of nutritional cultivation. The results indicated that, under Al stress, root reducing ability of Al-tolerant inbred lines was enhanced while TTC reducing ability decreased in Al-sensitive ones, which shows TTC reducing ability of root is closely consistent with the ability of Al-tolerance. The active absorption area in Al-tolerant inbred lines is much larger that of Al-sensitive ones, what’s more, the active absorption area to the total absorption area ratio is even higher compared with the Al-sensitive ones. The oxidbillity of root in Al-tolerant inbred lines could be maintained or slightly increased by aluminum stress while that of sensitive ones decreased. The results suggest that Al-tolerant inbred lines can keep high respiration metabolism when they stressed by Aluminum. The bleeding sap could be decreased in both inbred lines especially Al-sensitive lines when treated with Al.

The research was carried out on the effects of 7 agronomic characteristics of maize hybrids on their grain yielding stability, based on regional test materials of summer corns in North China, by using the correlation analysis between regression coefficient and characteristics. The results showed that most agronomic characteristics have negative relevance with yielding stability of hybrids. The most important factors are rows per spike and 1000 grains weight, while spike position and its length、plant height and grains per spike have little relevance. In the practice of breeding, such measures as enhancing selection of those characteristics which have little effects on yielding stability but great effects on grain yielding, properly lowering the height of spike position and increasing grains per spike, are all helpful to improve yielding stability of maize hybrids.

NIRS was a new method for quality analyzer in crop breeding. The kernel quality of 686 maize inbred lines in 2000 year-2001year and 1438 cross combinations in 2001year-2002year were analyzed in this paper by using near infrared spectroscopy transmission (NIT) analyzer, which was made by FOSS Company. The heterosis of crude-fat, protein and crude starch in corn kernel and the relativity between hybrids and their parents was discussed also. It showed that the range of variation and the coefficient of variation were larger for crude-fat and protein content, the variance range and the coefficient of variation of crude-starch were lesser, the average content was 4.24%～4.27%,11.75%～12.17% and 71.04%～71.10% respectively for the crude-fat, protein and crude-starch in inbred lines, and was 4.53%～4.86%，9.93%～10.05% and 72.56%～72.74% respectively in cross combinations.

Using super sweet corn inbreeding lines S1, S2, S3 and hybrid Yue Tian No.3 as materials, the efficient regeneration systems were established. The research showed that the genotype and length of immature embryo of super sweet corn were the key factors influencing the embryogenic callus development, 0.5-1.2mm immature embryo were better for embryogenic callus inducing. contents of sugar and cytokinins in medium were the main factors for plantlet regeneration, low content of sugar( 20g/L) and 6-BA（2mg/L）or Zeatin (3 mg/L) are more fit to the regeneration, and the rate of regeneration could be increased 1.68 times when callus treated with ABA in sub-culture for 3 weeks. IBA could improve plantlet rooting, and the content of 3.0mg/L was the best.

Crop coefficient of maize is one of the most parameters needs for crop water requirements.For estimating the evapotranspiration of maize objectively,in this paper,crop coefficient of maize were calculated by using the daily observational data of soil moisture of 1980～2002. The crop coefficient of maize in Liaoning's 5 areas were ascertained and the change of Kc during maize groeing period was analyzed.The Kc as sixth order polynomial functions of time(10 days) were derived.The results showed that the crop coefficient value of maize in Liaoning every area are obvious difference, but the change of their laws are comparatively unanimous.
