cotton is one of the most important crops in the world and increasing cotton yield is the main goal in the cotton industry. one important factor for crop improvement is increasing produced fibers by each developing seed. it is very interesting to manipulate fiber properties such as length, micronaire, color and strength which necessitate cotton ovule culture.  ovule culture is used as a tool to...

flame seedless is one of the most important and commercial table grape cultivar that is used for breeding program due to its specific characteristics of fruit high production. in order to breed new seedless grape cultivars and with considering importance of selecting seedless varieties as a female parent to increase the production rate of seedless offspring in a breeding cycle, embryo rescue te...

In the present study, in vitro ovule culture technique was used to obtain interspecific cross combination of Dioscorea rotundata ufenyi and Dioscorea bulbifera wild. Ten days after pollination, ovules were excised and cultured onto 1/2 strength Murashige and Skoog (MS) medium (Basal salt mixture + Vitamins) supplemented with 6% sucrose, 0.7% agar and plant growth hormones such as GA3, BAP, Picr...

This study was carried out in order to develop an embryo culture technique and establish breeding lines with this technique. Ovule preferred the because seeds were too small isolation difficult. Embryo cultures done by using populations obtained from producers Samsun, Denizli, Isparta, Mersin Turkey ?ameli black cumin variety. Hybridizations according semi-diallel hybridization method gain zygo...

The purpose of the present study was to determine the nature of the photoreceptor that controls the light-dependent development of the peanut ovule and embryo, and to determine whether this photoreceptor activity is located in the ovular or the embryonic tissue. Peanut ovules were aseptically excised from surface sterilized gynophores (pegs) and cultured in darkness, continuous far red (FR), or...

using haploid technique in breeding of sugar beet as an allogamous plant will facilitate breeding efforts. in this method,a pure line with a desirable genotype can be achieved by unfertilized ovule culture. therefore ovule culture was done from populations with numbers: 27621, 27624, 27626 and 27629. young flowering stems were collected and ovules were isolated from the flower buds after steril...
