“…The percentage of formed calli ranged from 1.3 to 77.9 (mean 30.6) ( Table 1). An alike result for embryogenic calli was obtained by Fennell et al (1996) for 48 elite bread wheats (0-67.7%), while Haliloglu et al (2005) obtained a better result (37.7-98.0%) with 25 wheat cultivars. The number of plants per embryo (PPE) ranged from 1.1 to 8.9 (mean 4.8) ( Table 1).…”

“…Plants were grown under rainfed conditions at the experimental field of the Centre for Agricultural and Technological Research, Zaječar, Serbia, during the 2002/2004and 2004/2005 seasons. A two-replicate randomised complete block design was used in the trials.…”

“…Many researchers found the variability of a tissue culture response of immature embryos in wheat (Sears and Deckard 1982;Chowdhury et al 1991;Machii et al 1998;Varshney and Altpeter 2002;Haliloglu et al 2005). It has become evident that a genotype used was of a major importance in the plant tissue culture response, although donor plant environment conditions and a culture medium composition have been considered as important factors too (see review of Sahrawat et al 2003).…”

“…Unfortunately, for a given genotype, a tissue culture response cannot be determined before being tested in experiments, which is very expensive, laborious and time consuming. In order to avoid the need to test large number of genotypes at the tissue culture step, Li et al (2003) and Haliloglu et al (2005) attempted to predict the outcome of tissue culture in advance by correlating some agronomic traits to crucial tissue culture traits. Their results suggested that it was possible to screen genotypes with good tissue culture traits directly at the agronomic level, a practice rather simple and straightforward.…”

There are only a few reports about the relationship between tissue culture and agronomic traits in wheat. In an attempt to enlarge the knowledge in this area, 96 wheat genotypes of worldwide origin were evaluated for their tissue culture response as well as the agronomic performance in the threeyear field trials. Plant regeneration was achieved from immature embryos collected 12-15 days after anthesis. Associations between tissue culture and agronomic traits were surveyed by the correlation and path coefficient analyses. A trait-association by year biplot was applied to understand environmental effects on these relationships. All significant traitassociations were of a moderate magnitude and were responsive to the environment. The path coefficient analysis revealed that a grain yield had the highest positive direct effect on a callus formation while the kernel number per spike had the highest positive direct effect on regenerative calli and plant number per embryo. Nevertheless, only productive tillering had significant (positive) direct effect on all studied tissue culture traits.

“…Although immature embryos are widely recognised as the most suitable explants to regenerate wheat plants (Bohorova et al, 1995;Kintzios et al, 1996;Li et al, 2003;Haliloglu et al, 2005), environmental conditions influencing the physiological status of field grown donor plants from which embryos were collected could be a limiting factor of their quality (Carman et al, 1988;Carman, 1995). Embryogenic competence of immature Sci.…”

Availability of immature embryos as explants to establish wheat (Triticum aestivum L.) by tissue culture can be limited by climatic factors and the lack of high quality embryos frequently hampers experimentation. This study evaluates the effects of rainfall, various temperature-based variables and sunshine duration on tissue culture response (TCR) traits including callus formation (CF), regenerating calli (RC), and number of plants per embryo (PPE) for 96 wheat genotypes of worldwide origin. The objectives of this study were to evaluate the significance of a particular climatic factor on TCR traits and to determine the period of wheat growth during which these factors were the most effective. The genotypes were grown in an experimental field during three seasons differing in meteorological conditions. The relationships between TCR traits and climatic factors within three time periods of wheat growth: 2, 6 and 10 weeks prior to embryo sampling were analysed by biplot analysis. The tissue culture traits were influenced at very different degrees by climatic factors: from 16.8% (RC) to 69.8% (CF). Donor plant environment with high temperatures and low rainfalls reduced (p < 0.05) the tissue culture performance of wheat genotypes. Callus formation was most sensitive to the temperature based factors. The environmental conditions between flowering and the medium milk stage were the most important for CF, while RC and PPE were not particularly related to any period.

Avaliou-se o efeito da chuva, de variáveis baseadas em temperatura e duração do brilho solar na resposta da cultura de tecido (RCT), incluindo a formação de calos (FC), regeneração dos calos (RC) e número de plantas por embrião (NPPE), para 96 genótipos de trigo. Os objetivos foram a procura de algum fator climatico específico em alguma característica da RCT e a determinação do período do desenvolvimento do trigo no qual estes fatores são mais eficazes. Os genótipos foram obtidos num campo experimental durante três estações climáticas. As relações entre as características da RTC e os fatores de clima dentro de três períodos de desenvolvimento do trigo (2, 6 e 10 semanas) antes da amostragem dos embriões foram analisadas pela técnica "biplot". As características das culturas de tecido foram influenciadas em diferentes graus pelos fatores climáticos: de 16.8% (RC) para 69.8% (FC). Ambientes da planta doadora com alta temperatura e pouca chuva reduziram (p < 0.05) o desempenho dos genótipos de trigo. A FC foi mais sensível aos fatores baseados em temperatura. As condições ambientais entre o florescime...
