Abstract Background Prunus tomentosa Thunb. is a fruit tree native to China and has wide natural distribution range. The germplasm resources are found in the six geographical regions of comprises variety ecological types. However, little known about genetic diversity population structure, with its abundant information. nuclear simple sequence repeat markers, biparentally inherited characteristics, powerful for evaluating population. And P. an important excellent plant material, high adaptability almost all soil types climatic conditions. So research contributed not only proposing scientific conservation strategies but also developing P. tomentosa breed novel cherry cultivar. Results A total 822 germplasms from 40 populations were used assessing structure tomentosa. indicators showed values, including observable heterozygosity (0.546), expected (0.819), Shannon’s information index (I = 1.951), polymorphism content (0.799). displaying greatest diversity—Gan-XlM, Shaan-HM, Gan-ZhC.

Abstract Background Phoebe zhennan, commonly known as “golden-thread nanmu,” is one of the most valuable and protection tree species in China. An accurate understanding population genetic structure its environmental factors significance for selection new P. zhennan varieties. Results Sixteen nSSR six cpSSR markers were used to determine diversity effect on structure. Low inbreeding (F = 0.237) high (I 2.294, h 0.412) observed populations. The differentiation was mainly detected within populations (only 28% 13% variance being between according datasets). Among them, HNSZX (h 0.469) SCSZZ 1.943) exhibited highest level diversity, while HNXXT 0.041) SCLJS 0.943) lowest diversity. average coefficient (Fst) gene flow (Nm) 0.022–0.128 1.698–11.373, respectively, which indicated a moderate flow. STRUCTURE, neighbor-joining clustering, principal coordinate analysis divided 543 individuals into two or three categories based datasets. Four temperature, precipitation, five chemical, physical, soil texture variable showed significant effects distribution Compared nSSR, among datasets conformed geographic isolation model, suggesting that distances should be considered further conservation breeding utilization. importance in situ units, such with more private alleles, haplotypes (e.g., SCGTS, SCYFS, YNYJX), emphasized. Additionally, breeding, along artificially assisted regeneration restoration, also carefully planned, taking account climate properties at same time. Conclusions In conclusion, this study provided background information conservation, management, utilization zhennan.

ABSTRACT Intersectional hybrids of Paeonia ( Itoh hybrids) have rich colours and strong fragrance, combining the advantages sect. Moutan , great economic value development potential. However, there been few studies on floral fragrance components intersectional . In this study, types contents volatile 20 were conducted. A total 53 volatiles identified though gas chromatography–mass spectrometry (GC–MS) analysis, with linalool, nonanal phenylethyl alcohol as main components. Based compound odour activity values (OAVs) cultivars classified into four aroma types: a scent, fresh spicy scent fruity scent. ‘Magical Mystery Tour’ had highest OAVs, potential for exploitation. This study provided theoretical reference selection parents flower breeding hybrids.
