haploid造句

The males are haploid.

An exact multiple of the haploid number is called euploid.

The paper introduced research development in male haploid inducer of maize, haploid induction, doubling methods and development of the research in Helongjiang province.

A high oil haploid inducer named CAUHOI released by China Agricultural University was used in the study of haploid inducing and doubling.

The haploid breeding of maize is a technology that using anther culture or gynogenesis to produce haploid, and then obtain stable new varieties through natural or artificial doubling.

That unfertilized ovaries were cultured to increase the induction frequency of haploid plantlets is also discussed.

The gender ratio of X chromosome and Y chromosome was almost same in the haploid.

Naturally doubling rate of haploid was significantly related with planted environment, not related with bas.

Anther culture has enhanced the capacity to generate large Numbers of haploid plants.

Potato haploid induction has significant meaning in potato breeding, It includes parthenogenesis and anther culture methods.

The basic set of chromosomes in a species is the haploid set, usually found in the gametes.

Meanwhile the ratio of haploid cell in the callus dropped gradually, and a lot of polyploid and aneuploid cells appeared.

According to the present direction, the key to the success for Potato breeding is to obtain double haploid.

The pea lectin gene was transformed into the haploid tobacco via Agrobacterium mediation using leaf disc method and the regenerated tobacco plants were obtained.

The paper reports the results of the study since 1993. The haploid plant from the culture of anthers and the clone of ovary without pollination have been obtained.

Polar nuclei The, usually two, haploid nuclei found midway along the EMBRYOSAC, forming a binucleate central cell. They may fuse to form the diploid definitive nucleus.

Through rice anther culture several kinds of ploidy plants can be obtained, such as haploid, diploid, polyploid and usually based on the morphology to distinguish their ploidy during maturity.

With these results, we are of the opinion that the abnormal expression of the isozyme genes of the haploid genome is due to lack of the interaction through another genome.
