GGE biplot analysis of multi-environment yield trials of rice produced in a temperate climate

Abstract

Low temperature is one of the main environmental constraints for rice (Oryza sativa L.) grain production yield. It is known that multi-environment studies play a critical role in the sustainability of rice production across diverse environments. However, there are few studies based on multi-environment studies of rice in temperate climates. The aim was to study the performance of rice plants in cold environments. Four experimental lines and six cultivars were evaluated at three locations during three seasons. The grain yield data were analyzed with ANOVA, mixed models based on the best linear unbiased predictors (BLUPs), and genotype plus Genotype × Environment interaction (GGE) biplot. High genotype contribution (> 25%) was observed in grain yield and the interaction between genotype and locations was not very important. Results also showed that 'Quila 241319' was the best experimental line with the highest grain yield (11.3 t ha -1 ) and grain yield stability across the environments; commercial cultivars were classified as medium grain yield genotypes.

“…Galur IR83383-B-B-129-4 adaptif di Purwakarta. Genotipe yang hanya unggul di lokasi tertentu dikategorikan memiliki daya adaptasi yang sempit (Sedghi-Azar et al 2008;Susanto et al 2015;Donoso-Ñanculao et al 2016).…”

GGE biplot analysis of vegetable type soybean genotypes under multi-environmental conditions in India

“…In the present study, E4 (Bengaluru) was nearer to the ideal environment selecting for wider adaptable genotypes. Similarly, using GGE biplot analysis, ideal environments have been identified in wheat (Mohammadi et al, 2010), sorghum (Rakshit et al, 2012, Gasura et al, 2015 and rice (Donoso-Ñanculao et al, 2015).

Correlation between grain quality of foxtail millet ( Setaria italica [L.] P. Beauv.) and environmental factors on multivariate statistical analysis

“…Zhao et al (2002) found growth period, precipitation, and altitude were strongly associated with foxtail millet amylase content. Although some papers have reported the effects of environmental factors on crop quality in wheat (Bornhofen et al, 2017), maize (Farrell and Gilliland, 2011;Lu et al, 2016), rice (Donoso-Ñanculao et al, 2016;Chen et al, 2017), pearl millet (Ullah et al, 2017) and oats (Marketta, 2008), little work has focused on the impact of environment on foxtail millet. Moreover, existing studies have focused on the relationship between individual quality indicators of foxtail millet and individual environmental conditions in single ecological regions of limited spatial scope.…”
