“…It is generally believed that the reason for the bursting of burst corn is that the silty endosperm in the center of the grain contains more water, which evaporates and expands when heated, and when the internal vapor pressure reaches a certain level [23], the grain is forced to explain suddenly, the pressure drops sharply, and the expansion of the grain is exploded into corn flower. There are many factors that affect the bursting quality of bursting maize.…”

Burst corn is a special type of corn specially used for making corn flower series snack food. Because there are few germplasm resources in burst maize, the breeding level and efficiency are restricted. At present, the yield of burst corn is low, the burst quality is not ideal, and the good germplasm resources are poor, which limits the development and utilization of burst corn. Burst quality is the key of burst corn commodity value. The improvement of burst corn must increase yield on the premise of ensuring good burst quality. This paper collected dozens of burst corn materials from home and abroad, and measured their burst quality, in order to screen out the excellent burst corn; At the same time, the hybridization and backcrossing offspring of burst maize and common maize, as well as the burst quality of burst maize's self-crossing offspring were determined in order to provide the basis for the breeding of burst maize varieties. The results showed that there were great differences in bursting quality among different bursting maize, such as yellow bursting l, stone bursting 2, Shanghai P2, Shanghai P4, 932, TP34, TP51, TP52, TP55 and red bursting 1, which had higher bursting rate and larger swelling multiples, reaching 99. 7%, 97.7%, 98.8%, 97.6,97.4%, 98.6,97.3%, 98.3% and 97.6%, respectively. Ordinary maize was hybridized with burst maize, and then the latter was used to cross back to the first generation. In the S1 and S2 generation of burst corn, the burst quality changed little, and the decline was not obvious.

These methods are technically simple, fairly cheap and generate a relatively large number of markers per sample.…”

Plum species are reported to possess a wide genomic variability and that is why DNA markers are still actual in the characterization of its germlasm. In this study, twentythree genotypes of European plums were assessed for the amplified length based polymorphism among the retrotransposon Cassandra insertions in their genomes. The obtained insertional polymorphism caused by the activity of Cassandra showed regional and pedigree differences in the analysed accessions of European plums. Two primers were used in analysis. The first resulted in the amplification in 203 amplicons and the 86.6 % polymorphism. Two unique fragments were obtained for the Torysa and Podolínec varieties using this primer. The second primer resulted in the amplification in 267 amplicons and 74.2 % polymorphism. Four unique fragments were obtained for the plum varieties Švestka domácí, Čačanská ranná and Elena. Hierarchical cluster analysis divided the analysed accessions into the four main clusters. To show the length polymorphism diferences of the analysed genotypes from Germany, Slovakia and former Yugoslavia more pecisely, the scattergram for them was constructed.
