Quantitative and qualitative yield in sweet maize hybrids

Abstract

Today, sweet corn is considered an important vegetable due to its high sugar content and low starch content. Cluster analysis and variance analysis showed that hybrids had variations in yield indices. GB, DE and GS hybrids had similar performance on indices. SE hybrid that has significant performance on zeaxanthin. Biplot showed that fructose, glucose, sucrose and potassium had stability value on hybrids. All the hybrids had the best performance on fructose, glucose, sucrose and potassium factors. Factor biplot positively correlated with yield indices, including calcium, iron, zinc, magnesium, α-Carotene, 9Z-β-Carotene, phosphorus, and β-carotene. On the other hand, there is a positive correlation with fructose, glucose, potassium, lutein, sucrose, β-Cryptoxanthin, and zeaxanthin. So, to evaluate or increase lutein and zeaxanthin, the other parameters like sugar content (fructose, glucose, and sucrose) are important factors and have an effect together. Factor analysis and biplot showed that ME hybrid had a maximum performance on the first factor of yield indices. Also, the second factor of yield indices had a maxi-mum effect on NO hybrids. SE hybrids had maximum performance in zeaxanthin and GS hybrid had maximum performance in zinc, phosphorus, and iron. The dry matter had stability on DB hybrid.

Stability yield indices on different sweet corn hybrids based on AMMI analysis

“…Some authors have even used the Pearson coefficient for a two-valued variable and a distance/relative variable. Interpreting Pearson correlation can also be logical when one variable is bi-value (containing only two levels) (Ilker, 2011;Shojaei et al, 2021;Mousavi et al, 2022;Bodnár et al, 2018). Cluster analysis is a statistical method for grouping data or observations according to their similarity or degree of proximity.…”

Cross-Breeding Improvement and Performance Analysis of Dominant Production Traits in Grazing-Type Alfalfa (Medicago sativa L.)

“…A previous preliminary study showed that RSA-03 had significant heterosis in both the aboveground biomass and stem thickness, which is consistent with the results of this study [ 11 ], indicating that RSA-03 has a prominent yield advantage. Additional studies on the advantages of different hybrid combinations in yield traits showed that, and the results varied depending on the variety used [ 30 – 32 ]. Thus, we speculated that yield performance indices of rhizome-rooted hybrid strains are affected by a combination of both the variety used and environmental factors.…”

Application of correlation coefficients and principal components analysis in stability of quantitative and qualitative traits on rice improvement cultivation

“…There was a negative correlation between the number of full seeds and the number of tillers, According to the angle of 180 degrees between the vector of these two traits (Figure 2C). Various researchers used correlation diagram to determine the degree of correlation between traits in their research on different plants, which can be mentioned in corn (Shojaei et al, 2020;Mousavi et al, 2022), sunflower (Ansarifard et al, 2020, canola (Shojaei et al, 2011).…”
