“…The frequencies of in vitro plant regeneration of cereals are commonly influenced by genotype (Sears and Deckard 1982, Hanzel et al 1985, Rakoczy-Trojanowska and Malepszy 1993, Fennel et al 1996, Özgen et al 1998, Satyavathi et al 2004, Zale et al 2004, composition of culture medium (Powell and Caligari 1987, Mendoza and Kaepler 2002, Satyavathi et al 2004 and environmental conditions (Lazar et al 1984). Once the genotypes for desirable characters are screened by preliminary evaluation, transfer of such desired genes to elite germplasm can be attempted.…”

“…Once the genotypes for desirable characters are screened by preliminary evaluation, transfer of such desired genes to elite germplasm can be attempted. This approach requires knowledge of the genetic basis for in vitro aptitude and will also help to predict the response of these characters to selection (Caligari et al 1985, Powell andCaligari 1987). On the other hand, hybrid vigour can also be important in these experiments.…”

The effect of heterosis on callus induction, callus mass and number of regenerated plants from mature embryo cultures of winter durum wheat (Triticum durum Desf.) hybrids was studied. A total of 14 F 1 hybrids and their parents were used for mature embryo culture. The statistical analysis of the results revealed that positive heterosis in callus mass was determined in only one F 1 hybrid and in number of regenerated plants in two F 1 hybrids. Plants regenerated in vitro were successfully established in soil. Hybrid genotypes may be used to obtain callus and regenerated plants with vigour comparable to their parents.

“…These techniques allow rapid multiplication, germplasm conservation and improvement of several crop species (Rolando et al, 2010). The effective use of tissue culture techniques, such as micropropagation, haploids obtaining, in vitro selection, somaclonal variation exploration, and the possibility of genes introgression, among others, depends on the capability to initiate and establish in vitro cultures (Gogoi et al, 2013;Powell and Caligari, 1987), which is directly related to the germination and development of the species.…”

ABSTRACT. The objective of this study was to estimate the genetic effects on in vitro germination and development of chili peppers. For this, four genotypes were used as parents. They were crossed in a complete diallel scheme. The parents (4) and hybrid (12) seeds were germinated in glass bottles containing MS media. The following variables were evaluated: seed germination percentage, deformed seedlings percentage, radicle emission percentage, root length, root number, hypocotyl length, hypocotyl width, definitive leaf number, leaf length, and leaf width. The data were submitted to analysis of variance and the means were grouped by the Scott-Knott criteria (P ≤ 0.05). The diallel analysis was performed according to the Griffing method, method I, fixed model. Significant differences for all analysed variables were observed. Additive and non-additive effects were observed influencing the performance of the genotypes in relation to the evaluated variables. The genitor 132 showed the highest general combining ability for almost all evaluated characteristics, except seed germination percentage and deformed seedlings percentage. This study revealed dominance effects are responsible for genotypic variation for almost all evaluated traits. In addition, we found significant reciprocal effects for all studied characters. For the traits to which non-additive variances were important (germination percentage, deformed seedlings percentage, root number, hypocotyl length, hypocotyl width, and definitive leaf number, leaf length, and leaf width), there was an additional opportunity for developing F 1 hybrid.

“…Tissue culture response has been shown to be under genetic control in several crops such as wheat (Lazer et al 1984, Ou et al 1989, Zamani et al 2003, maize (Tomes and Smith 1985), rye (Rakoczy-Trojanowska and Malepszy 1993), pearl millet (Mythili et al 1997) and barley (Powell andCaligari 1987, Komatsuda et al 1989). It has been found that in many crops the performance of in vitro cultures is affected by genotypes, medium components, explants and other environmental conditions.…”

SummaryThe influence of hybrid vigor on callus induction, culture efficiency, callus weight, regeneration capacity of the callus and number of regenerated plants from callus culture of sugarcane was studied. For the study a total of 6 parents (clones of S. officinarum and S. spontaneum) and 12 F1 hybrids were used. The statistical analysis of the results revealed that positive heterosis was noticed for callus induction, callus weight and number of regenerated plants.
