To protect the identity of orchid cultivar and the right of the breeders, we successfully develop a novel method by the introduction of foreign DNA sequence (27bp) as molecular marker via BioWare low pressure gene gun into Mormodes lawrence and Zygopetalum mackayi. Histochemical GUS transient expression was obtained from aleurone layer and embryo of Zea mays using BioWare low pressure gene gun with acceleration pressure of 50psi. This is the first report on successful transfer into plant tissue using BioWare low pressure gene gun.

There is a new northern bean made available to farmers and breeders that can resist common bacterial blight – and it is high-yielding too. Named "ABC-Weihing", the bean cultivar was developed by University of Nebraska bean breeder Carlos Urrea, and Phil Miklas, a geneticist at the Agricultural Research Service using marker-assisted selection. The new bean variety resisted eight strains of bean rust and all non-necrotic strains of bean common mosaic in greenhouse tests, and also had an average seed yield of 1,869 pounds per acre.

The main characters of new cotton hybrid JiH239 were analysed based on the results of Hebei Cotton Regional Test in 2003~2004. The results showed that JiH239 was high yield, disease-resistance and fiber length and strength were better than CK cultivar, micronaire value was a little high. The Bt toxic protein gene expression levels was higher than bollworm-resistant CK Zhongmiansuo41 in different growing period. The purity of bollworm-resistant was higher than Zhongmiansuo41 in seeding period and no significant variety in bud period and flower-boll period.
