摘要
以巴西巴拉那州推荐种植品种BR-16、CD 201和CD 206为材料，研究了大豆种质资源人工杂交效率。BR-16 × CD 206和CD 201 × CD 206在7个不同的时间进行杂交:上午8:30，上午10:00，上午11:30，下午1:00，下午2:30，下午4:00和下午5:30，在控制条件下，在巴拉那州北部Cambe镇的温室中进行杂交。采用随机完全区组设计，6个重复，分区处理。结果表明，传粉成功率完全取决于母本基因型。BR-16品种的传粉成功率一直低于CD 201，因此在人工杂交过程中需要更加小心处理。该数据证实了在温室控制条件下全天对大豆进行人工杂交的可能性，增加了进行大量杂交组合的有效能力。
Cultivar x day period interaction effects on soybean artificial cross efficiency
Efficiency of artificially crossing soybean germplasm was investigated using the BR-16, CD 201 and CD 206 cultivars, which are recommended for cropping in Parana state, Brazil. The BR-16 x CD 206 and CD 201 x CD 206 hybridizations were carried out at seven different day of times: 8.30 am, 10.00 am, 11.30 am, 1.00 pm, 2.30 pm, 4.00 pm and 5.30 pm under controlled conditions in a greenhouse, in the town of Cambe, northern Parana state. A randomized complete block design with six replications and treatments in split plots was used. The results indicated that the efficiency, evaluated as percentage of successful pollinations, depended exclusively on the female parent genotype. The BR-16 cultivar requires more careful handling during artificial hybridization because its percentage of successful pollination was consistently lower than that of CD 201. The data confirmed the possibility of conducting artificial hybridizations in soybean throughout the day under controlled conditions in a greenhouse, increasing the effective capacity of carrying out a large number of hybrid combinations.
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 The article must be unpublished.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.
