“…The inheritance of quantitative characters is complex, and many genes has a minor contribution to the phenotype. Inheritance of quantitative characters is generally studied by estimating population parameters (Rosmaina et al 2016;Candido et al 2017;Rohaeni and Yunani 2017;Coelho et al 2019).…”

Abstract. Rosmaina, Elfianis R, Almaksur A, Zulfahmi. 2021. Minimal number of morphoagronomic characters required for the identification of pineapple (Ananas comosus) cultivars in peatlands of Riau, Indonesia. Biodiversitas 22: 3854-3862. Pineapple (Ananas comosus L Merr) is a tropical fruit that has high economic value. In Riau Province, Indonesia, pineapples grow and produce well on various types of land, including the highly acidic peatland. There are many types of pineapples grown by from generation to generation, but so far, there have been no reports regarding the diversity of pineapples in peatlands. This study aimed to determine the minimal number of characters distinguishing pineapple morphological and agronomic characters in peatlands. The observations were done on 24 local genotypes of pineapple in peatlands. Characterization were carried out on 49 morphological and agronomic characters according to the Pineapple descriptor from the International Board for Plant Genetic Resources (IBPGRI). The data were analyzed by Multivariate Analysis, in which the principal components analysis was used for qualitative and quantitative traits. Based on the results of this study, there were at least 12 characters proposed to describe pineapple in peatlands, viz. seven qualitative characters (fruit base leaf color (collar), fruit shape, bractea color, fruit eye profile, fruit eye surface, flesh color, crown attachment to fruit) and five quantitative characters (fruit weight, fruit flesh weight, plant height, number of leaves and leaf length). Out of the 49 traits observed, 12 selected characters can be used as a minimal number of characters that can be used to identify pineapple cultivars on peatland. The findings of this research are rewarding for the conservation and management of genetic resources, selection, and breeding activities of pineapple plants.

“…Maron et al (2010), Guimarães et al (2014), Matonyei et al (2017), and Matonyei et al (2020) revealed that this genomic region (ZmMATE1) explains most of the phenotypic variation of Al tolerance in Cateto maize. The greater tolerance observed in the germplasm of landrace maize in the present study could also be directly related to the presence of the same genes coming from the Cateto breed of maize, a germplasm that is very common in the region these landrace varieties of maize were collected (Coelho et al 2018).…”

The aims of this study were to evaluate the homology of the ZmMATE1 and ZmMATE2 gene sequences with those deposited in the international banks of sequences and quantify the differential expression of the genes ZmMATE1, ZmMATE2, and ZmNrat1 in germplasms of landrace and hybrid maize under aluminum (Al) stress in minimal solution. Fifty-two hybrids from different companies and 50 landrace varieties were genotyped for the genes ZmMATE1 and ZmMATE2. For studies of gene expression, the tolerant (H 44 and V 18) and the sensitive (H 22 and V 25) genotypes were exposed to minimal solution containing 4 mg L -1 of Al for different periods (0

“…Quantitative traits have complex inheritance, conditioned by many genes with small individual effects, and are greatly affected by the environment. In these cases, the inheritance and variation of traits are studied on the population level through estimation of genetic parameters (Candido et al 2017, Rohaeni and Yunani 2017, Sakulphrom et al 2017, Coelho et al 2019. Cabral et al (1997) reported that segregations for leaf types was in accordance with the frequencies expected from the Collins and Kerns (1946) 2-gene model, with the Primavera cv.…”

Leaf spinescence in pineapple plants was evaluated in a total of 2.014 F1 individuals as follows: 1.125 plants of the progeny of the Imperial BRS cv. × Pérola cv. cross, and 889 plants of the progeny of the Pico de Rosa cv. × BRS Imperial cv. cross. The genetic hypothesis with two loci and epistatic interaction of the piping (P) over spiny (S) trait was tested. The chi-square test was performed on deviations between the observed and expected numbers based on the genetic hypotheses formulated. The "BRS Imperial" × "Pérola" and "Pico de Rosa" × "BRS Imperial" progenies segregated into 1:0:1 (spineless:spiny tip:spiny), expressing phenotypes of their respective parents. The spineless leaf ("BRS Imperial") is determined by the "Ppss" genotype, with the locus "P" in heterozygosity and the locus "S" in recessive homozygosity. The spiny leaf margin ("Pérola" and "Pico de Rosa") is controlled by the "ppss" genotype.
