Transgenic tomato plants with tobacco osmotin gene and bean basic chitinase gene together with the NPTⅡmarker gene were applied in this experiment. A kanamycin spraying test was carried out on 3 successive generations （T, T, T） of several transgenic lines with varied T-DNA copy number detected by. Southern blot on To generation. Three-week transgenic seedlings as well as the non-transformed control growing in tray in greenhouse or growing on open seedling bed were sprayed from above with 100 mg/L

Perennial ryegrass is clearly one of the most important and widely used forage and turf grasses, exhibiting rapid establishment, good tillering ability and high acceptability to *** genetic relationship of 16 ryegrass cultivars, including 2 accessions annual cultivars and 14 entries perennial cultivars, from different breeding company were analysed using 61 RAPD markers. 61 RAPD primers generated 408 bands, of which 367 bands (89.95%) were polymorphic;It showed that the genetic polymorphism in these cultivars was very low, the coefficient among the cultivars fell between 50%～95%;Dendrograms obtained using this molecular markers are not in agreement with their separated morphologic character. High correlation was not obersved between the two annual ryegrass *** from the same company were not clustered in one *** breeding method of perennial ryegrass was discussed.

The brown planthopper (BPH), Nilaparvata lugens Stl, is a devastating sucking insect pest of rice (Oryza sativa L.) throughout the world. Resistance to BPH is an important breeding objective in rice improvement. Bph15 is one of the major BPH resistance genes so far identified in several indica rice and wild relatives. In previous studies, Bph15 was identified in an introgression line B5 and mapped on the, region near the centromere of chromosomes 4 flanked by RFLP markers C820 and S11182.

To detect QTLs controlling traits of agronomic importance in rice, two elite lines HR5 and Zhengshan97, which are significant difference in plant height, heading date and spikelet per panicle etc, were crossed. Subsequently a single-seed-descend procedure was employed to produce 190 recombinant inbred lines （F）. On the basis of this population a molecular linkage map comprising 177 SSR markers was constructed. Composite interval mapping and interval. mapping was used to detect QTLs for such important agronomic traits as heading date （HD）, plant height （PH）, 1000-grain weight （KGW）, seed setting ratio （SSR）, panicle length （PL）, grains

In this paper, a new species of Octopus (Octopoda, Cephalopoda) was found in the materialcollected from the south-east waters of China, named Octopus tankahkeeei sp. nov.. Type specimen Holotype Female DOXUC-M20, and paratype Male DOXUC-M30 were preserved in Department of Oceanography of Xiamen University.
