Faba beans are considered one of the most important crops for animal feed. The genotype × environment interaction (GEI) has a considerable effect on faba bean seed production. objectives this study included assessing multiple locations and genotypes to understand how various ecosystems relate another, suggesting ideal climatic conditions, crop management system, so that they carefully chosen their stability. A 2-year experiment was conducted in order define stability across four environments...

It is generally recognized that clovers represent a major nutrient used in ruminants’ diets due to their composition, which high protein content and low fiber content. Investigating the nutritional quality of red white clover genotypes, classifying genetic materials according primary attributes were main goals current study. During two-year experiment, we assessed performance stability. Twelve (Trifolium pratense L.) twelve repens cultivated randomized complete block experimental design....

The indices for yield and main quality characteristics such as plant height, number of nodes, the green mass dry matter, crude protein fiber (%), ash were examined. Statistical analysis revealed significant differences that indicated presence high genotype–year interactions. Heritability higher in case qualitative traits than quantitative traits. most intriguing correlation between...

Abstract: The predatory effect of adult ladybird Coccinella septempunctata L. on adults thrips, Thrips tabaci Lindeman, and whiteflies, Trialeurodes vaporariorum (Westwood), was examined in controlled environment chambers, tomato leaves, transparent small plastic cages at proportions 1/(10 + 10), 1/(20 20), 1/(30 30) 1/(40 40) predator/number thrips whiteflies. We conclude that C. could be used with success for the biological control whiteflies greenhouse crops, almost same effectiveness as...

Five were used in a strip-plot design. Correlations showed significant positive relation between seed some other traits. Indirect improvement may be implemented by improving pod length, which generally high indices Greek mega-environment. Comparisons farming...

The primary purpose of this study was to explore yield stability common vetch varieties based on the index, with a specific aim exploring variety behavior regarding legumes under both conventional and low-input cultivation systems. Six (Vicia sativa L.), namely, cv. Filippos, Omiros, Alexandros, Tempi, Zefyros Pigasos, were used. conducted using strip-plot design six randomized within each plot in two farming systems (conventional low-input). Filippos best for seed yield, followed by Omiros....

Breeding in maize (Zea mays L.) succeeded improving tolerance to stresses and responsiveness inputs, but failed improve the potential yield per plant. Modern hybrids are highly productive, their unit area is dependent on high plant densities. Results of present study verified that modern require a narrow range densities give maximum area, since density affected significantly all kind genetic materials. also showed associated with plant-to-plant variability barrenness, affecting negatively...

Common vetch (Vicia sativa L.) is a widespread legume crop in the Mediterranean mega-environment, due to its versatile uses and compatibility with organic low-input farming systems. However, adaptation various such environments should be studied varieties suitable for forage yield must selected. This study aimed explore stability of common based on index, specific target variety behavior environments. Six Greek were used over four two years. The cultivation was conducted using strip plot...

One of the main obstacles to finding cultivars with consistent performance across locations and years is genotype × environment (GE) interaction effect. A new approach stability analysis for qualitative characteristics in maize was conducted utilizing G E interactions further via AMMI GGE biplots. The study aimed identify type trait inheritance through estimations index, evaluate multiple genotypes determine how different ecosystems relate one another, and, finally, suggest ideal climatic...

Stability for yield and seed quality across environments are desirable traits varieties used the support of livestock, such specific common vetch (Vicia sativa L.) peas (Pisum sativum highly demanded from farmers. The objective this study was to investigate stability performance attributes on six genotypes five pea genotypes. genotypes’ were based characteristics under low-input vs. conventional cultivation systems. Significantly positive or negative correlations between main in all schemes...

The purposes of this study were to define the kind trait inheritance through stability estimations various traits in maize, relationship between different environments and maize hybrids, propose best hybrids for farmers. Field experiments conducted two years (2011 2012) at four locations Greece: Florina, Trikala, Kalambaka Giannitsa which selected as they represent environments. genetic materials tested a Randomized Complete Block (RCB) design, 15 F1 commercial open-pollination lines...

The stability of performance may be proved to the last frontier for adopting certain genotypes in various cultivation systems and environments. main objective present study was analyze forage yield seven pea (Pisum sativum L.) based on indices. genotype behavior studied peas under both conventional low-input systems. Five cultivars (broadly distributed) two lines were used a strip-plot design. Significant positive correlations detected between some other traits. This way, indirectly improved...

Abstract: The objectives of this study were to determine the depth penetration into soil by Frankliniella occidentalis (Pergande) and Thrips tabaci Lindeman (Thysan., Thripidae) in cucumber tomato crops greenhouses. A metal sampling apparatus sampled for two species thrips at five levels (0–10 cm), over seven dates sampling, each eight replications. In general, found be greater numbers first 2 cm soil, with number insects decreasing increasing. 8–10 cm, no found. Number under plants was...

Traits affecting fibre quality were evaluated in a multi-location environmental experiment. Four main cotton regions Greece selected as different environments. Five commercial cultivars used for evaluation of 10 traits. Each cultivar was sown fields each region. Environmental fluctuations within affected trait differently showing degree inheritance. traits showed the lowest stability index values indicating quantitative inheritance, further four with intermediate indicated determination by...

Correlation between twenty-one traits was studied in plants of F2 generation derived from crosses groundnut varieties. Also, correlation for the same within four types used: Virginia x Virginia, Valencia Valencia, Spanish and Valencia.
