摘要

以巴西橡胶树(Hevea brasiliensis) 10个无性系为材料，研究开花与胶乳产量之间的互作关系，以确定不同采胶季节的无性系稳定性。选取尼日利亚产的7个无性系和进口的3个无性系，根据橡胶树的开花模式，对3个季节的胶乳产量进行了评价。利用方差分析和5个稳定性参数对5年乳胶产量数据进行克隆变异和稳定性评价。不同季节、无性系和无性系间的互作对乳胶产量有显著影响。3个尼日利亚无性系(NIG 800、NIG 803和NIG 804)乳胶产量超过进口无性系。3个无性系NIG 802、NIG 805和RRIC 45在3个季节中表现稳定，可以作为稳定基因的供体亲本。

Interaction between flowering pattern and latex yield in Hevea brasiliensis Muell. Arg.

The interaction between flowering and latex yield was evaluated in 10 clones of Hevea brasiliensis to determine clonal stability across tapping seasons. The clones, consisting of seven clones developed in Nigeria and three imported clones, were evaluated for latex yield in three seasons according to the flowering pattern of Hevea trees. Latex yield data collected in five years were evaluated for clonal variation and stability using analysis of variance and five stability paramet ers. There was significant variation of latex yield across seasons, clones, and interaction of clone x season. Three Nigerian clones (NIG 800, NIG 803, and NIG 804) surpassed the imported clones in latex yield. Three clones (NIG 802, NIG 805 and RRIC 45) were stable across the three seasons and could serve as donor parents for stability genes.

期刊介绍： The CBAB – CROP BREEDING AND APPLIED BIOTECHNOLOGY (ISSN 1984-7033) – is the official quarterly journal of the Brazilian Society of Plant Breeding, abbreviated CROP BREED APPL BIOTECHNOL. It publishes original scientific articles, which contribute to the scientific and technological development of plant breeding and agriculture. Articles should be to do with basic and applied research on improvement of perennial and annual plants, within the fields of genetics, conservation of germplasm, biotechnology, genomics, cytogenetics, experimental statistics, seeds, food quality, biotic and abiotic stress, and correlated areas. The article must be unpublished. Simultaneous submitting to another periodical is ruled out. Authors are held solely responsible for the opinions and ideas expressed, which do not necessarily reflect the view of the Editorial board. However, the Editorial board reserves the right to suggest or ask for any modifications required. The journal adopts the Ithenticate software for identification of plagiarism.
