Inheritance of in vitro response in wheat

Serbian Genetics Society

2004

The inheritance of in vitro culture response was studied by using immature embryos from five wheat cultivars and their reciprocal hybrids. In vitro culture response was evaluated according to callus formation, percentage of regenerative calli and the number of plants per embryo. By crossing the cultivar Vesna (VS) with highest tissue culture response and the two cultivars with lowest response Leda (LD) and Zajecarska 65 (ZA), it was demonstrated that the regeneration potential was heritable. VS as female parent, enhanced regeneration response in hybrids VSxLD and VSxZA, while as a male parent, VS did not affect the regeneration ability of hybrids LD and ZA. However, hybrids having LD and ZA as a male parents exhibited a decreased regeneration potential, as compared to self-pollinated VS. The results suggest the presence of a class of extra-nuclear factors in the VS cultivar. They significantly account for relatively higher regeneration capacity in the hybrids having this cultivar as a female parent than in those where the VS was male parent

Analysis of morphological traits of bird's foot trefoil plants cv. Bokor transformed with Agrobacterium rhizogenes

An efficient method for genetic transformation and shoot regeneration was achieved in bird's foot trefoil cv. Bokor using A. rhizogens. The transformed shoots were regenerated on hairy root segments in high frequency. After rooting and acclimation, transformed To plants were grown in experimental field. Analysis of morphological traits and chemical content in ten unintentionally chosen To bird's foot trefoil plants (genotypes no. 2 and no. 5) was performed. They were compared to those of control...
