“…In addition to decreased lodging susceptibility, Zandonadi, Coolong, and Pfeiffer (2010) indicated that shorter plants presented higher harvest efficiency compared to taller plants. Genotypic morphology, such as plant height and number of nodes per plant, was likely affected by differences in genetic background (Mebrahtu & Devine, 2008), corroborating findings of the present study.…”

Evaluation of edamame genotypes suitable for growing in Florida

et al. 2020

Edamame, or vegetable soybean, has gained popularity in the United States, likely due to its nutritional quality, purported human health benefits, and flavor. Little information is available about the performance of current edamame cultivars in Florida areas. The objective of this study was to evaluate yield and production potential of edamame genotypes in northern Florida. Nineteen genotypes (based on preliminary study) were selected and planted at two locations (Jay and Citra) to evaluate phenotypic performance, including emergence, plant height, nodes per plant, 100-green seed weight, fresh pod yield, percentage of 1-, 2-, and 3-seeded pods, total lipid concentration, and total protein content. Genotypes and locations showed a significant effect on most of the traits studied. Edamame grown at Jay produced significantly higher yield and 100-green seed weight than the plants grown at Citra. Two early maturing genotypes (PI614832 and PI584470) and one late maturing genotype (PI633424) showed high yield potential, >30 g of 100-green seed weight, and high protein content at Jay. In addition, PI417206 showed the highest 100-green seed weight across locations (50.81 g) and demonstrated moderate yield potential with high protein content and low lipid concentration and may be a suitable candidate for cultivation in different areas in Florida after further evaluation. Number of pods per plant and 100-green seed weight significantly correlated with pod yield, could be considered as selection tool for edamame yield under Florida growing conditions. This study has established a basic knowledge on edamame production for Florida growers and selected lines suitable for the region.

“…In self-pollinated crops such as soybeans, it is expected to find a predominance of additive effects for most traits in early generations (Spehar 1999;Mebrahtu and Devine 2008). Tolerance to rust is expected to have a polygenic inheritance and a predominance of additive effects (Ribeiro et al 2008), which is similar to those found in the present study.…”

Uni and multivariate approaches for diallel analysis in early generation trials for soybean tolerance to rust

et al. 2019

Due to the high impact of Asian soybean rust (SBR) in Brazilian croplands, several studies have been conducted in order to maintain or increase the grain yield gain over years in the presence of the pathogen. The aim of this study was to define a breeding strategy applying uni and multivariate approaches for diallel analyzes in early generation trials and contrasting disease conditions. Thus, assessing genetic parameters to identify traits related to greater tolerance to soybean rust. Deploying a North Carolina design II scheme (4 elite commercial cultivars × 10 rusttolerant experimental lines), we obtained 40 F 2 crosses that were evaluated in a randomized complete block design with 4 replicates. The crosses were conducted in two environments, contrasting only for the fungicide management (with and without rust control), enabling the estimation of the rust impact on 11 traits, divided

“…It was buttressed by Malik et al, (2007), Udensi et al, (2012) and Burno et al, (2017). On the other hand, plant height negatively significant with single plant yield was reported by Mebrahtu and Devine (2008) and Li et al, (2013). Even though plant height in turn increases the plant vigour and may lead to unnecessary vegetative growth, it is recommended to have the crop with semi dwarf stature to improve the yield (Diondra, 2008).…”
