Breeding Maize for Tolerance to Acidic Soils: A Review

et al. 2018

View full text Add to dashboard Cite

Acidic soils hamper maize (Zea mays L.) production, causing yield losses of up to 69%. Low pH acidic soils can lead to aluminum (Al), manganese (Mn), or iron (Fe) toxicities. Genetic variability for tolerance to low soil pH exists among maize genotypes, which can be exploited in developing high-yielding acid-tolerant maize genotypes. In this paper, we review some of the most recent applications of conventional and molecular breeding approaches for improving maize yield under acidic soils. The gaps in breeding maize for tolerance to low soil pH are highlighted and an emphasis is placed on promoting the adoption of the numerous existing acid soil-tolerant genotypes. While progress has been made in breeding for tolerance to Al toxicity, little has been done on Mn and Fe toxicities. More research inputs are therefore required in: (1) developing screening methods for tolerance to manganese and iron toxicities; (2) elucidating the mechanisms of maize tolerance to Mn and Fe toxicities; and, (3) identifying the quantitative trait loci (QTL) responsible for Mn and Fe tolerance in maize cultivars. There is also a need to raise farmers' and other stakeholders' awareness of the problem of Al, Mn, and Fe soil toxicities to improve the adoption rate of the available acid-tolerant maize genotypes. Maize breeders should work more closely with farmers at the early stages of the release process of a new variety to facilitate its adoption level. Researchers are encouraged to strengthen their collaboration and exchange low soil pH-tolerant maize germplasm.

“…Tandzi et al (2015b) characterized some of the selected inbred lines under acidic soil with aluminum toxicity whereas Petmi et al (2016) screened inbred maize lines for adaptation on acid soils in the humid forest zone of Cameroon. However, no studies have been conducted to provide agro-morphological information such as emergence rate of plants, prolificacy, appearance of the ear and grain yield on the promising varieties of maize hybrids developed by Tekeu et al (2015). This study was investigate to characterize the agro-morphological performances of maize hybrids varieties under acidic soils conditions with aluminum and manganese toxicities.…”

Acidic soils cover 75 to 80% of the arable soils in the humid forest areas of Cameroon, causing maize yield losses of around 69%. Sixty-four accessions of maize hybrids were developped from “Line × Tester” crosses between twenty tropical inbred lines with three testers (Cam inbgp117, 88069 and 9450) and between testers themselves, and one acid tolerant open pollinated variety (ATP-SR-Y). Those inbred breeding lines were collected from CIMMYT, IITA and IRAD and the derived single hybrids were characterized using agro-morphological maize’s descriptors on a completely randomized block design in two contrasting environments (Nkoemvone and Nkolbisson). The data collected was subjected to multivariate analyses. The Principal Component Analysis showed the first two components being 73.60% and 78.99% of the total variation in Nkoemvone and Nkolbisson, respectively. Furthermore, grain yield showed a positive and highly significant correlation with the plant emergence rate in Nkoemvone (r = 0.61, P < 0.001) and Nkolbisson (r = 0.84, P < 0.001). Hierarchical Clustering Analysis indicated that these accessions forms four distinct groups, where each of the groups showed clear specific features for which the performance differs from that of the others in Nkoemvone and Nkolbisson. Characters such as plant emergence rate, prolificacy, ear appearance and grain yield have been found as important phenotypic markers for assessing agromorphological diversity of maize hybrids. These traits should necessarily be considered in maize breeding programs for varietal discrimination and formulation of cores collection of maize tolerant to aluminum and manganese toxicities in the soil.

“…Al toxication damages the plasmalemma of root cells and thus inhibits the absorption of nutrients and water ( Rahman et al 2018;Pidjath et al 2021). High soil acidity in the tropics can result in a 38-80% reduction in maize yields (Tandzi et al 2015;Tekeu et al 2015). The potential yield of maize in acid soils with 45-70% Al saturation ranges from 1.55 to 3.76 t ha -1 (Evans et al 2013;Hayati et al 2014).…”

Abstract. Herawati, Riadi M,MusaY, Efendi R, Azrai M. 2023. Evaluation of the growth and tolerance of maize lines under aluminum stress. Biodiversitas24: 1417-1430. Breeding and utilization of Al-tolerant maize are among the technological applications for preventing a decrease in the growth rate and grain yield of maize in suboptimal fields. This study aimed to determine the growth and production of maize lines under Al stress, obtain maize lines that are tolerant to Al stress, and determine Al absorption in the tested maize lines. This study comprised two steps. In the first step, maize lines were evaluated in acid soils with a pH of 5.12 and an Al saturation of around 22.13%, while the normal condition was carried out on soil with a pH of 6.60 and 0% Al saturation. The study was arranged in a randomized block with three replications. The maize lines used were 24 genotypes consisting of 20 maize lines and four elite lines as a check (Mal 03, CLYN 231, G102612, B11209). In the second step, maize lines were evaluated in the nutrient solution. This study was arranged in a split-plot design with three replications. The main plot was the concentration of Al at three levels, i.e., 0, 7, and 14 ppm. The subplot comprised seven maize lines representing sensitive, medium tolerant, and tolerant categories. They were Pop. A3-1, Pop. A7-1, CB.Pop 10-1-3-1-2-2, CB.Pop 15-4-2-1-1-1, CB.Pop 23-1-2-1-4-2, Mal 03, and G102612. These studies were conducted at the Indonesian Cereal Research Institute, Maros, South Sulawesi, Indonesia, from August 2021 to January 2022. This study showed that Al stress could reduce plant growth by around 10.84% to 50.51% and grain yield by around 62.23% compared to normal conditions. The traits that were significantly correlated with grain yield under Al stress (r>50%), which could be used in maize selection under Al stress, were the number of live plants, ear diameter, number of kernels per row, shelling percentage, SSI, crown Al absorption, and hematoxylin staining. There were two maize lines tolerant to Al stress, namely CB.Pop 11-2-3-4-2-1 and CB.Pop 15-4-2-1-1-1, with potential yields under Al stress conditions of 2.39 t ha-1and 1.59 t ha-1, respectively. Al absorption averages of roots and crowns of Al tolerant maize lines were 159.33 ppm and 36.33 ppm, respectively.
