The paper reviewed the course of the enlighten and initiate stage (1926-1948) for the investigation of heterosis utilization in maize(Zea mays L.), and the development course of crosses between cultivar, double, three-way and single cross after the found of the Peoples Republic of China since 1949. The paper point out the distinguishing feature and obvious advantages of the development for hybrid maize investigation in our country. The success of some main force inbred lines that bred by integrated method and technology during this time will draw great inspiration effects from their experiences to future breeding. The improved hereditary traits, breeding objectives, breeding ideas for future breeding and the question of heterosis definition were discussed and prospected. It is demended in future breeding that raising the density-tolerant cultivar, single-plant heterosis under less density, no stress and resistance to bioltic and abioltic adverse circumstances in a mode rate degree, and some physiological characters of photosynthesis function etc.

Based on the genectic theory of “multiple fertility genes cytoplasmic-nuclear interaction male sterility”, through systemic explorations and studies, a new male sterile cytoplasm called new cytoplasmic resource (CMS-FA) was discoverd and identified from a common wild rice, which is different from the types of CMS-WA and CMS-HL in the relationship of restoration and maintenance. A series of fine quality male sterile lines for CMS-FA hybrid rice have been developed and identified. JinnongⅡyou3, the first developed CMS-FA hybrid rice combination took part in Fujian province rice new cultivar regional trial for two years in 2007 and 2008. The average yield was 9.025% higher than that of the control and its rice quality reached third class indica rice quality standards. CMS-FA hybrid rice contributes to the genetic diversity of hybrid rice cytoplasms, the improvement of hybrid rice quality and yielding potential, and the unification of hybrid rice high yield and superior quality. It will add new strength to the innovation and development of hybrid rice.

The paper gives an overview of the achievements in soybean breeding of Huajiang institute. Using plant type selection, Huajiang institute successfully give a solution of the contradiction between thriving & flourish and poor aeration & light transmissivity with the yield risen considerably. The contradiction among high oil, early maturity and high yield is solved, which fills a gap of planting high oil soybean in the cold area of northern Heilongjiang. The soybean varieties cultivated by Huajiang institute are the primary ones in northern Heilongjiang and Inner Mongolia, which were planted over 0.667 million hm2 every year. A detailed introduction of experience of soybean breeding is summarized.

Taking the two japonica rice varieties Songliao 06-6 and Jiyu japonica as test materials, genetic characteristics such as ear size, number of grains, grain weight were studied. The materials were planted in their off-site multi-point normal cultivation conditions for three consecutive years 2006-2008. Results showed that:  the yield of the varieties and ear number, grain number, seed setting rate,  have reached significant levels, while ear length and kernel number per spike does not meet the significant level. It is initially defined that the high-yield of japonica rice varieties mainly due to good plant type, the ideal, tillering, paniclerate, grains per spike and seed setting rate, which provide reference value data for breeding high yield and stable yield japonica varieties.

Based on a wide range of germplasm collection, accumulation and organization research on maize inbred lines from 1957 to 2004, Wu 105 and Yuanwu 02 group were classified into the second category of ten populations of maize pedigree. Wu 105 was successfuliy applied in top-cross and double cross hybrids, three-way cross, early-maturing single cross hybrids, subsequently bred Shaanxi 1, Huangbai 1, Shaandan 7 and so on. Later,  Wu 105 gave rise to the Wu 109, Tian 4 and other improvement inbred lines, making up some major promotion hybrids such as Shandanhao, Hudanhao, etc.  Shandong Academy of Agricultural Sciences bred Yuanwu 02 by radiation treatment, then bred follow-up derived lines such as Yuanqihao, Luyuan 133, Luyuan 92, forming a new derivative branches, to be widely used in our country. The inbred lines derived from the follow-up  new and improved varieties occupied a large proportion in Jiangsu province, and also be applied in Jilin Tonghua and Fujian.  Wu 105 germplasm expansioned from west to east, from south to north, enriched maize germplasm gene pool of our country.

Using PEG 6000 concentrations of 20%, 22%, 24%, 26% simulating drought stress,  germination rate for interspecific hybrids rapeseed of different resistance (tolerance) and drought was analizied in field experiments. To show the effects that PEG6000 simulate drought strees in selecting rape resistance (tolerance) materials. The results showed that 22%~24% PEG6000 and germination time for 4~8 d are suitable for handling rape seed in selecting resistance (tolerance) rapeseed. When the concentration of PEG6000 treatment in less than 22%, the germination index can be used as an essential indicator for reference.

With the development of facilities protected field and the demand of market, the watermelon in greenhouse developed rapidly in recent years. Greenhouse watermelon intercropping sweet potato is a new simple agricultural technologies which could help farmers efficient increase the income. The regularly planting space of sweet potato is 25 cm. Subjected to the constraints of watermelon line space, the density of sweet potato is 26 250 plant/hm2. Low density would effect the yield benefits. Tests prove that when the planting space reduce to 17 cm, density of 37 500 plant/hm2 is more reasonable.

The correlation between seed color and leaf color of 126 shares of red-seed cultivated adzuki bean germplasm resources was studied with the CIE L*a*b* color order system. The results showed that seed color was closely related with leaf color for the sort of secondary early-maturing and middle-maturing adzuki bean in Beijing area. Degree of correlation between seed color and leaf color was higher in the peak period of bearing pods than in other period. It would be of more possibility to obtain the materials of fine seed color by selecting seed color indirectly by leaf color, selecting the plants of dim brightness and light green leaf in peak period of bearing pods.
