Multiploidy occurrence in tomato calli from anther culture

New findings in strawberry (Fragaria × ananassa Duch.) anther culture

In this research, some independent experiments were carried out for investigating the effects of microspore developmental stage, bud pretreatments (cold, heat and Ca), and embryo induction medium on anther culture of some strawberry cultivars. The results showed that the percentages of responsive and embryogenic anthers in cultivar Paros in liquid medium were influenced not only by different de...

Useful Diversity via Multiploidy

AbstTactA multiploid genetic algorithm (GA) incorporates several candidates for each gene within a single genotype, and uses some form of dominance mechanism (most simply, an encoded choice) to decide which choice of each gene is active in the phenotype. We explore a simple multiploid model. Investigation with two simplified test problems is reported, respectively suggesting certain strengths a...

Anther culture of iranian wheat germplasm using different media

Single gene mutations in tomato plants regenerated from tissue culture.

Plants were regenerated from cultured leaf explants of an inbred variety of Lycopersicon esculentum. Seeds were collected from the regenerated plants and sown in the greenhouse. The resultant plants were then evaluated in the field. Several monogenic mutations segregated in the progeny of regenerated plants. The recovery of single gene mutations is evidence that plant tissue culture can be muta...

Colchicine induced embryogenesis and doubled haploid production in maize (Zea mays L.) anther culture

This study involves in vitro androgenesis of <sp...
