Embryo rescue from interspecific crosses in apple rootstocks

Rootstocks for Size Control in Apple Trees

In situ embryo rescue for generation of wide intra‐ and interspecific hybrids of Panicum virgatum L.

Wide crosses have been used for decades as a method for transferring novel genetic material and traits in plant breeding. Historically, many products of wide crosses require tedious and inefficient surgical embryo rescue prior to embryo abortion to recover single plantlets. We have utilized transgenic switchgrass (Panicum virgatum L. cv Alamo) as a pollen donor in conjunction with antibiotic or...

Production of Cucurbita Interspecific Hybrids Through Cross Pollination and Embryo Rescue Technique

Interspecific hybridization is an important method to widen variations and to develop novel cultivars. Interspecific cross-pollination was carried out among three species of Cucurbita (C. moschata, C. ficifolia and C. martinezii) as male parents with ten cultivars of C. pepo as female parents. Only four cultivars of C. pepo (Eskandarani cv., Queen F , Jedida F and MHTC77 F ) were successful in ...

Epistatic control of non-Mendelian inheritance in mouse interspecific crosses.

Strong deviation of allele frequencies from Mendelian inheritance favoring Mus spretus-derived alleles has been described previously for X-linked loci in four mouse interspecific crosses. We reanalyzed data for three of these crosses focusing on the location of the gene(s) controlling deviation on the X chromosome and the genetic basis for incomplete deviation. At least two loci control deviati...

Interactions in Interspecific Crosses between Members of the Tomato Clade

One premise of the biological species concept (BSC) is that reproductive barriers act to prevent interbreeding between species. While the BSC is not universally applicable, interspecifi c reproductive barriers (IRBs) between species can be detected in many cases. For example, in the tomato clade ( Solanum sect. Lycopersicon ) prezygotic IRBs can prevent hybridization between certain species ( R...
