1. The invention provides a technique for inducing autopolyploid by using peppermint shoot tips, which can be used for breeding peppermint autopolyploid.

2. The autopolyploid B 97 differ widely from its parents diploid in biological characteristics.

3. The seeds from the self-bred autopolyploid rice were used to study the characters of those progenies.

4. The above-mentioned results indicate that the formation of autopolyploid and allopolyploid may be related to the level of inbreeding depression.

5. The seeds from the self - autopolyploid rice were used to study the characters of those progenies.

6. Autotetraploid An autopolyploid that has four times the haploid number of chromosomes.

6. try its best to gather and create good sentences.

7. Establishment of allopolyploids is favored because of greater niche separation from their diploid progenitors, and taxonomists appear reluctant to name phenotypically cryptic autopolyploid species.

8. To improve Gynostemma yield quality and resistance, firstly we have established fast propagation system through tissue culture, and then induced autopolyploid with colchicines.

9. The technique is applied in the polyploid breeding practice on jujube trees, the method is simple and convenient, and the autopolyploid can be quickly obtained and applied in production.

10. For crop improvement, haploidy enables the achievement of rapid homozygosity, enhanced selection efficiency for recessive genes, and breeding at a diallelic state for autopolyploid species.
