Stability analysis of sugarcane (Saccharum spp) genotypes for matric and quality traits by AMMI Model

Abstract

The experiment across nine environments (three cuttings × three locations) was conducted during 2009-10 and 2010-11 crop seasons to study the effect of genotype × environment interaction (GEI) on a cane, CCS yield and sucrose (%) in sugarcane (Saccharum spp). Analysis of variance of 10 genotypes revealed that genotype, environment and GEI were highly significant. The additive main effects and multiplicative interaction (AMMI) model was used to interpret the behaviour of genotype, environment and their interaction. In fact, the objective of this study was to identify stable and adaptable genotypes across the locations and to determine the magnitude of G×E interaction. AMMI analysis of variance showed that 52.93% of the total SS for cane yield, 60.48% for CCS yield ad 56.0% for sucrose (%) was attributed to the environmental effects, indicating that the locations were diverse. The PCA-1 and PCA-2 were also significant and both sums contributed cumulatively to 66.84% to the total of G×E interaction. The genotype CoP 05437 (4) exhibited high cane and CCS yield along with wider stability and adaptability to the different environments. However, BO 91 (8), CoSe 092423 (10), CoSe 05452 (5), Co 05019 (2) and CoBln 04174 (7) genotypes showed instability and specific adaptability to the environments, while CoP 09301 (9) genotype showed higher sucrose (%) and greater stability across the environments for this trait.

Stability analysis for cane and sugar yield of advanced sugarcane (Saccharum officinarum) genotypes

“…However, a higher value of S 2 d i indicates unstability of genotypes over varied environments. Similar, results have earlier been reported Tahir et al (2013), Guddadamath et al (2014), Tiwari et al (2011), Kumar et al (2007) and Dubey et al (2017). Whereas, the genotypes CoSe 92423, BO 91 and CoSe 05452 exhibited S 2 d i non-significant and regression coefficient (b i ) less than unity (b i <1) with a mean value higher than the population mean indicated genotype stability and suitability under unfavorable environmental conditions for sucrose per cent in juice.…”

“…The mean performance of genotypes over several locations due to G×E interactions is not much reliable parameter alone for prediction of their stability for the traits. Therefore, under such condition genotypes should be screened individually in specific locations to maximize cane yield and CCS yield (Gauch 1990, Ebdon and Gauch 2002, Kumar et al 2007.…”

The Increase of National Sugar Production as a Form of Achieving the 2nd SDGs through Mutation Breeding

“…Genotypes are specific-location if they are far from the main axis but closer to the ecological line, while the genotype is stable if the genotype is close to the main axis [16]. This result is reinforced by [17] [18] and [19] that a test genotype that is close to the (0.0) axis is stable. Thus, the genotype that showed stability in three locations based on AMMI analysis was BL, M1 (Figure 1a).…”

Exploring the Impact of Organic-Inorganic Coupling on Nutrient Use Efficiency and Cane Yield in Calcareous Soils of the Indo-Gangetic Plains of India

“…According toThakur et al (2012), cane juice quality, including brix, sucrose, and purity content, is unchanged by the use of organic and conventional farming methods. According to research bySinha et al (2014) andKumar (2012), both organic and inorganic nutrients had no impact on the juice's quality indicators of brix, pol, and purity.…”
