“…Our results are supported by the findings of Gulumbe et al (2018). Results for bulb yield were supported by the studies of Pavlović et al(2015). From the present results of heterosis and heterobeltiosis, four combinations were observed with maximum values for bulb yield and its contributing traits.…”

Exploration of genetic variation may help to select diverse parents for open pollinated variety and hybrid development program in onion (Allium cepa L.). Thirty-five onion genotypes were analyzed by two-way cluster analysis and principal component analysis (PCA) on the basis of phenotypic traits. These genotypes were grouped in five different clusters. PCA provided information for variation in genotypes on the basis of studied traits. Ten genotypes were selected from five diverse clusters and hybridized in a line × tester mating fashion. Twenty-four F1 combinations were developed and raised along-with parents for assessment of hybrid vigor, commercial heterosis and genetic correlation. Data was analyzed for morphological and biochemical traits. Maximum commercial heterosis (heterosis computed over commercial standard/check variety) for bulb yield per plot was observed in combination MKS-SGB × MKS-GBP-01, MKS-57404 × Super Sarhad and MKS-SGB × Mustang (55.77%, 36.70% and 32.90%), respectively. Maximum better parent heterosis for bulb yield per plot was in combinations MKS-SGB × MKS-GBP-01 (31.01%), followed by MKS-TEG × Mustang, MKS-57404 × Super Sarhad and MKS-SGB × Mustang (13.76%, 12.49% and 11.79%), respectively. Genetic correlation coefficient showed that bulb yield per plot showed highly significant and positive association with single bulb weight, bulb diameter, significant positive association with leaf density (number of leaves per plant), leaf width (diameter) and significant but negative association with total soluble solids. Yield per plot showed a negative association with days to maturity. Present study revealed that cluster analysis and PCA can play an important role in effective parent selection without compromising genetic diversity for development of potential hybrids for commercial exploitation.

“…The main component of onion yield is the bulb mass that together with plant density per area unit has a direct impact. Bulb mass is a morphological marker and represents the variety trait impacted by edaphic and ecological factors (PAVLOVIĆ et al, 2002;PAVLOVIĆ et al, 2012;PAVLOVIĆ et al, 2015). Bulb height directly determinates its form, which impacts the usage of onion bulbs (markets, industrial proceeding), market value, etc.…”

The success in growing agricultural plants depends on genotype grown, environment and growing technology applied. The impacts of these factors should not be studied separately. Interaction among genotypes and environment was crucial for breeding work and improvement of variety characteristics. Very often in production practice it happens that when comparing the same varieties in different soil and weather conditions they are ranked differently. One of the key aims set at the breeders is breeding for the traits of wide adaptability and calculating of the complex components of genetic variance which is the main condition for successful breeding program such as breeding for increased yield and yield components. Trial was set up at random block system in five repetitions. Ten onion genotypes from the Institute for Vegetable Crops germplasm were used in this trial. After choosing the most stabile genotypes, they were crossed by applying full diallel without reciprocals. Then, a field trial was set up with parents and hybrids of F1 and F2 generation. The experiment has been set up at the trial field of the Institute for Vegetable Crops in Smederevska Palanka, for three years. The best adaptability in the experiment, for mass of the onion bulb had genotypes Makoi bronzi and Holandski žuti, while for average yield, it was Jasenički crveni. Also, components of genetic variance in both progeny generations were calculated for mass, yield and height of fresh bulb. The most common heredity mode for mass and yield of the bulb was super-domination and domination of a better parent.

“…Bulb weight and the realized bulb set per unit area are the components that directly determinate onions yield, implying the importance of the traits for both breeders and producers (PAVLOVIĆ et al, 2015). According to the analysis of variance of AMMI model for onion bulb weight and number plot -1 harvested from the conventionally and organically maintained plots in the two-year field trial, all sources of variation were highly significant (Table 1, 2).…”

This study was aimed to assess the stability of direct yield components (bulb weight and number plot-1) and other yield contributing characteristics (bulb diameter, height and index, neck diameter and length, plant height, emergence and vegetation period) in five commercial onion cultivars grown in conventional and organic environments, by employing additive main effect and multiplicative interaction (AMMI) statistical model in data analysis. The two-year field trial organized in complete randomized blocks included the plots maintained in four regimes: mineral fertilization (conventional), without fertilization, fertilization with farmyard manure and with bacterial fertilizer (organic). Each treatment by year combination was considered as an environment. Analysis of variance of AMMI model calculated for the investigated traits showed that all sources of variation (genotypes, environments, genotype by environment interaction) were highly significant. The largest proportions of the total sum of squares were encompassed by environments, except for emergence and bulb index with the pronounced effect of genotypes (67.26 and 52.54%, respectively) and neck length with the genotype by environment interaction amounting 44.59%. Generally, the effects of the interactions were in the common range. The AMMI model with two axes was concluded as the best model for the investigated traits. Onions grown in conventional system outperformed the organic ones. However, good performance of the genotypes was accompanied with low stability across the environments and vice versa. Therefore breeding programs intended to develop cultivars adapted to alternative production systems should rely on the experiments set in the corresponding environments that include various combinations of genotypes and agro-technical procedures based on the principles of organic agriculture.
