The invention belongs to the technical field of plant biotechnology, and specifically discloses a method for rapidly identifying chromosome ploidy of an avena plant. An SSR (Simple Sequence Repeats) molecule is utilized to mark characteristics that avena plants with different ploidy have different sizes and copy numbers, and the chromosome ploidy of the avena plants can be identified rapidly by combining a PCR amplification technology and a gel electrophoresis technology by virtue of different numbers of amplified product segments. The method for rapidly identifying chromosome ploidy of the avena plant has the advantage that ploidy of the plant can be identified rapidly under the condition that the ploidy of the avena plan is not known in advance, and the method is applicable to avena plants.

The invention discloses an exploring method for a biological genome simple repeat sequence, which is characterized by comprising the following steps of: forming a regular expression according to the characteristics of the biological genome SSR (Simple Repeat Sequence) needed to be explored; analyzing a to-be-analyzed sequence according to the regular expression, judging whether the to-be-analyzed sequence contains a target SSR meeting the requirement of the regular expression, if so, outputting the target SSR; if not, displaying information about that the to-be-analyzed sequence contains no target SSR. Thus, the exploring method and the exploring device for the biological genome simple repeat sequence cannot generate redundant result in a SSR exploring process, so that the configuration complexity of the SSR exploring process is reduced, SSR exploring efficiency is improved and difficulty in development of SSR exploring software is reduced.

The invention discloses a primer pair, a castanopsis hystrix SSR1 (Simple Sequence Repeat 1) marker and a preparation method and application thereof. According to the preparation method, the total DNA (Deoxyribonucleic Acid) of castanopsis hystrix is subjected to PCR (Polymerase Chain Reaction) amplification by using the specific primer pair HZ1, thereby obtaining the SSR1 marker. The method is simple and feasible and is simple and convenient in operation; shown by tests which are carried out in members of two natural castanopsis hystrix populations and among the members, the obtained SSR has relatively high polymorphism. The castanopsis hystrix SSR1 marker is a co-dominant marker; compared with other molecular markers, the SSR marker is good in repeatability and high in reliability, can be applied to the genetic diversity evaluation of castanopsis hystrix, the genetic map construction of castanopsis hystrix, the research on the spatial distribution pattern of the genetic variation of castanopsis hystrix population and the origination and evolution of castanopsis hystrix and the standardization of target genes, and can also be applied to the molecular marker assisted breeding and QTL (Quantitative Trait Locus) research of castanopsis hystrix.

The invention discloses hibiscus cannabinus L. drought response gene EST-SSR primers and a kit. 11 pairs of primers are provided, and one pair or multiple pairs of primers are used as EST-SSR polymorphism markers for identifying the genetic relationship of hibiscus cannabinus L., the genetic diversity or the differences of simple repeat sequence polymorphisms in specific exon regions of drought-related genes. The hibiscus cannabinus L. drought response gene EST-SSR primers and the kit disclosed by the invention have the benefits that a good marker reserve is provided for molecular marker-assisted breeding of the hibiscus cannabinus L., and a candidate molecular marker for detection is also provided for functional allelic variation of key genes screened in the natural variation of the hibiscus cannabinus L.

The invention discloses a high-throughput typing technique universal to various molecular markers and belongs to the field of molecular biology. By the use of hybrid template production of 5' terminal biotin labeling, a target area having single-nucleotide polymorphism, simple sequence repeat, insertion deletion, copy number variation and the like and containing various molecular markers and target areas such as exon and species specific single-copy areas can be subjected to capturing and gene typing; meanwhile, allele quantitative typing and precise quantitative detecting are both considered; site selection flexibility of the solution hybridization is combined with the advantages of the high-throughput sequencing technique, such as high throughput and low cost. Compared with the use of the existing molecular marker typing technique, the use of the high-throughput typing technique solves the problems such that the existing fixed-point molecular marker typing technique is available for only typing single molecular markers and unavailable for typing various markers at the same time or precisely and quantitatively detecting alleles, and production of random markers or unlabeled hybrid templates is limited.
