Research progress of plant cytogenetics in Jiangsu province.

Cytogenetics was established based on the "Chromosome theory of inheritance", proposed by Boveri and Sutton and evidenced by Morgan's lab in early stage of the 20 centrary. With rapid development of related research areas, especially molecular genetics, cytogenetics developed from traditional into a new era, molecular cytogenetics in late 1960s. Featured by an established technique named DNA in situ hybridization (ISH), molecular cytogenetics has been applied in various research areas.

Inter-simple sequence repeat data reveals high genetic diversity in wild populations of the narrowly distributed endemic Lilium regale in the Minjiang River Valley of China.

Lilium regale E.H. Wilson is endemic to a narrow geographic area in the Minjiang River valley in southwestern China, and is considered an important germplasm for breeding commercially valuable lily varieties, due to its vigorous growth, resistance to diseases and tolerance for low moisture.

[Efficient plant regeneration in vitro in Pinus massoniana L].

Pinus massoniana L. is one of the important trees for afforestation in South China. The efficient system of plant regeneration from mature zygotic embryos and seedlings of masson pine was established in this study.
