Popcorn parental selection based on genetic divergence
Nine popcorn genotypes were assessed for eight traits and their genetic divergence was estimated by multivariated techniques to identify parents for inclusion in breeding programs involving hybridization. The nine genotypes were divided into two groups by the Tocher method using the generalized Mahalanobis distances. The popping expansion, popcorn size and grain mass per plant were considered the most important agronomic traits for selecting parents for crossing. Using the divergence and these trait scores as criteria for crossing, the crosses between genotype 9 (group II) and genotypes 8, 3, 7, and 5 (group I) were recommended. Therefore, only four (11%) out of 36 possible (diallel) crosses among the nine assessed genotypes would be made.
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 The article must be unpublished.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.
