摘要

本研究以绿玉米生产为目标，采用群体内循环选择和再组合的方法选育后代，产生开放授粉群体。为此，在2017/2018第二季，以PMVJ01和杂种AG1051为对照，对PMVJ01群体(TG-02R2与AG1051杂交后代重组而来)的后代进行了评价。评估了以下参数:开花、高度、绿穗产量、谷壳覆盖、穗径和穗长、产量、穗形、穗上行数、行排列、籽粒颜色、谷壳宽度和长度。利用Mulamba和Mock在4个选择过程中的指数和5个选择过程中的多变量方法，估计遗传参数，预测20%的后代的增益。在种群中发现了遗传变异，这使得选择过程得以推进。重组后产生的两个群体显示出作为开放授粉品种使用的潜力。

Genetic variability and recurrent selection in corn population with potential for green corn production

The present study selected progenies, aiming at the production of green corn, by methods of intrapopulation recurrent selection with subsequent recombination, generating open-pollinated populations. To this end, in the 2017/2018 second season, progenies from the PMVJ01 population (originated from the recombination of progenies of the TG-02R2 x AG1051 cross) were evaluated, using PMVJ01 and the hybrid AG1051 as controls. The following parameters were evaluated: flowering, heights, green ear yield, husk cover, ear diameter and length, mass yield, ear shape, number of rows on the ear, alignment of rows, color of kernels, and husk width and length. Genetic parameters were estimated, and the gain was predicted with the selection of 20% of the progenies, using the index of Mulamba and Mock in four selection procedures and a fifth by multivariate method. Genetic variability was found in the population, which allows advances in the selection process. After recombination, two of the populations generated showed potential for use as open-pollinated cultivar.

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 The article must be unpublished.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.
