Polyploidization is an important technique used in grape breeding to create new genetic resources and can be induced using some antimitotic agents, including colchicine. Plants with increased ploidy can gain better quality than their original diploids in some characteristics. "Induction of polyploidy in grapevine (Vitis vinifera L.) seedlings by in vivo colchicine applications" was carried out to obtain polyploid genotypes under in vivo conditions.

A study was conducted at Bangladesh Agricultural Research Institute’s greenhouse with 48 maize genotypes through hydroponic culture. Morphologically, plants behave differently in low phosphorus conditions than in normal phosphorus environments. Large augmented roots were found in the plant in low phosphorus conditions. The results revealed that chlorophyll contents, shoot length, root length shoot dry weight, root dry weight, leaf area, and root/shoot ratio might be considered critical traits for screening low phosphorus tolerant maize at the seedling stage.

"Evaluation of Lonicera caerulea L. genotypes based on morphological characteristics of fruits germplasm collection" is known that a polymorphic population consisting of a large number of genotypes adapts more rapidly to the environment conditions. The availability of a large gene pool predetermines the success of the introduction and further breeding of new cultivars with economically valuable features. Morphometrics is a classical tool for studying the amplitude of the variability of cultivated plants and evaluating the genotypic diversity of the artificial population.

High-throughput/high-content microscopy-based screens are powerful tools for functional genomics, yielding intracellular information down to the level of single-cells for thousands of genotypic conditions. However, accessing their data requires specialized knowledge and most often that data is no longer analyzed after initial publication.

The parental genotype P2 recorded the highest number of branches per plant (7.85 and 6.94 branches) under well watered and rainfed treatments, respectively. While, the two crosses; P2 · P4 and P2 · P6 recorded the highest number of pods per plant in both generations under well watered and rainfed treatments.

The results of studies on the resistance control to Septoria tritici with alloplasmic lines of bread winter wheat with 14 cytoplasms. The effect of the Triticum aestivum L nuclear genome on its interactions with the cytoplasms of related species on wheat resistance was found out. Analyzing the obtained resistance evaluation results of the genotypes involved in the pathogen Septoria tritici experiment showed the absence of immune forms under the conditions of the Forest-Steppe of Ukraine.

This study was carried out in Mediterranean climate and under rainfed conditions in Turkey for a period of three years throughout the growing seasons of 2014/2015, 2015/2016 and 2016/2017. It was conducted in a randomized complete block experimental design (RCBD) with three replications. In present study, genetic diversity for agro-morphological characters and macro/microelements were investigated in sixteen promising local faba bean genotypes originated from Turkey. According to the results of the study, mean grain yield varied from 2320 kg ha–1 (Tekirdağ-39) to 3130 kg ha–1 (Burdur-50).

Drought is a major threat to wheat production worldwide and development of drought-tolerant wheat genotypes may improve the production of this cereal crop in drought affected regions. In the present study, 24 mutant lines were developed by treating a wheat variety ‘NN-Gandum-1(NN-1) with ethyl methane sulfonate (EMS). The M5 , M6 , and M7 generations were evaluated for quantitative traits under well irrigated and rainfed conditions. Furthermore, best performing mutants of M6 and M7 generations were examined for biochemical parameters.

Mustards occupy an important place among oilseed species due to their considerable economic and nutritional value and multiple uses. This study made use of 77 mustard genotypes collected from the USDA gene bank and diverse ecologies of Turkey to determine the extent of morphologic variability among them. The genotypes were screened to select genotypes appropriate for use in mustard breeding programs during 2015–16 and 2016–17 under the Mediterranean rainfed conditions of Yenimahalle (spring sowing and autumn sowing) and Haymana (spring sowing).

The aim of this study was to confirm the presence of BADH gene and control whether it plays an important role to protect white clover (Trifolium repens L.) against oxidative, salt, and drought stresses. Three genotypes possessing BADH and 1 genotype lacking BADH were selected, considering the expression levels of BADH in response to methyl viologen mediated oxidative stress. The genotypes possessing BADH displayed significantly less ion leakage under oxidative stress treatment, compared to that lacking BADH.

miRNAs have been characterized as a regulator of main processes in plants by silencing genes. The functions of microRNAs have been studied in various crops, hovewer, no studies have been observed about miRNAs in Italian rygrass (Lolium multiflorum L.) against drought stress. This experiment aimed to reveal the involvement of miRNAs against drought stress in sensitive and tolerant Italian ryegrass genotypes. Four genotypes (G1 and G2 as drought sensitive – G3 and G4 as drought tolerant) were selected.

One of the major effects of salt stress is high production of reactive oxygen species that adversely affect essential cellular metabolic pathways. To limit the elevated production of reactive oxygen species, plants stimulate various types of antioxidants. In this study, sulfur was used to induce tolerance against oxidative stress through modulation of the activities of various antioxidants. Two maize genotypes (Agatti 2003 and Pak Afgoi 2003) were subjected to different salinity (25 and 75 mM) and sulfur (40 and 80 mM) treatments and a control treatment.
