摘要

摘要与没有矮化基因的番茄植株相比，矮化番茄植株更短，冠层直径更小，在成熟过程中保持直立，从而减少了果土接触，从而获得更健康的果实。本研究评估了携带矮化基因的BC1F3群体的番茄家族的工业产量。150个BC1F3家族和两个亲本（杂交H-9889和登录BGH-9889）作为对照，在具有四个复制的扩增块设计中进行评估。对数据进行方差分析和F检验。选择指数基于Mulamba和Mock（1978）的等级总和，用于基因型的选择，考虑了最相关的性状，即冠层直径、产量、倒伏和果实硬度。因此，选择的产量增加了8.04%。

Evaluation of families derived from backcrosses of processed tomato with dwarfism gene

Abstract In comparison to tomato plants without the dwarfism gene, dwarf tomato plants were shorter, had a smaller canopy diameter and remained upright during maturation, thereby reducing the fruit-soil contact, resulting in healthier fruits. This study evaluated tomato families of a BC1F3 population carrying the dwarf gene for industrial yield. The 150 BC1F3 families and the two parents (hybrid H-9889 and accession BGH-9889) as controls were assessed in an augmented block design with four replications. The data were subjected to variance analysis and the F test. A selection index, based on the sum of ranks of Mulamba and Mock (1978), was used for the selection of genotypes, considering the most relevant traits, i.e., canopy diameter, yield, lodging and fruit firmness. Thus, selection resulted in a yield gain of 8.04%.

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 The article must be unpublished.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.
