Herein provided is a new potato variety designated UNR-01 as well as the tubers, seeds, plants, plant parts, and derivatives of the new potato variety UNR-01. This transgenic variety was generated using CRISPR-Cas9 and deleting a portion of the StMYB93 (PGSC0003DMG400006408) gene. This transgenic variety has a sprout suppressed phenotype that results in a longer storage life in cold storage conditions without the application of sprout-inhibiting chemicals. These potatoes were not impacted in reduced sugar levels, wound healing capacities, and native periderm suberin content. Also provided are tissue cultures of the new potato variety UNR-01 and the plants regenerated therefrom. Methods for producing potato plants by crossing the new potato variety UNR-01 with itself or another potato variety and plants produced by such methods are also provided. UNR-01 potatoes exhibit suppressed sprouting and longer storage life in cold storage conditions without the application of sprout-inhibiting chemicals.

Disclosed is a self-incompatible dihaploid potato and a production method therefor, and a hybrid potato and a seed production method therefor. The production method includes the following steps: haploid-inducing a diploid potato carrying one or more heterozygous self-compatibility genes by a haploid induction line, and screening haploid mutants; selecting a haploid mutant which does not contain any self-compatible gene; and performing chromosome doubling on the haploid mutant which does not contain any self-compatibility gene to obtain a self-incompatible dihaploid potato line. The self-incompatible dihaploid potato is used as a female parent for seed production, such that emasculation may be avoided, hybrids do not bear fruits, and the yield of the potato is increased.

Disclosed are use of a polynucleotide, protein, and biological material in the regulation and control of plant tuber development, and related products and production methods thereof. The tuber plant or part thereof, comprising a sequence encoding a polypeptide comprising a sequence having at least 92% sequence identity to SEQ ID NO: 2, wherein the polypeptide is inhibited-expressed, loss-function, or overexpressed, and the development of plant tuber is changed. The polynucleotide is an identity gene of a tuber, and can control whether a tuber is formed, the formation time, the tuber size etc. by regulating and controlling a protein function, an expression quantity etc.

The present application relates to the technical field of genetic breeding, and provides a method for identifying whether a diploid potato is self-compatible. The method relates to identifying whether a StSCI gene in the diploid potato is transcribed and expressed. Also disclosed is a method for identifying whether a StSCI gene is expressed by using molecular marker, and a method of screening for the molecular marker, which includes: obtaining the genome sequence information of parental materials, screening for difference sites of the parental materials, screening for the molecular marker, and identifying whether the screened molecular marker are usable. As for the identification of the self-compatibility of a diploid potato by using the screened molecular marker, the identification workload is small, a lot of time is saved, and the identification result is not affected by the environment, and it is accurate and reliable.
