Bent branches are commonly utilized in cut roses to enhance commercial flower quality through increased nutrient production and biomass. However, the ideal number of bent concerning crop water productivity remains unknown. The experiment was conducted Jinning, Yunnan, 2022 with total three growth periods 1–3 branches. Sap flow a branch measured using heat ratio method assess rose transpiration during each period. Across harvests, plant height by 87.9% compared those one (217 cm). Fresh weight 63.6 g shoot−1, 135% more than branch. produced 56% high-grade (grade A grade B) shoots other treatments. Daily 4.09 mm d−1 across which 115% higher economic value 54% two 120% Crop 14.7 kg m−3, 84.7% 167% Our results help farmers optimize irrigation greenhouse conditions could be used improving models quantifying at level.

Identification of major and stable QTLs conferring drought tolerance in rice RIL populations

Current Research in Biotechnology, Год журнала: 2023, Номер 5, С. 100125 - 100125

Опубликована: Янв. 1, 2023

Rice production in a rain-fed environment during the reproductive period is significantly hindered by drought, which one of critical issues limiting yield. Therefore, finding grain yield-related quantitative trait loci (QTL) stage can potentially provide researchers with additional benefits when taken context marker-assisted breeding. CT-9993 and Samba Mashuri were considered to develop recombinant inbred lines (RILs) for tagging QTLs associated drought tolerance. During dry wet experimental conditions, there was significant difference yield yield-attributing variables. Sixty polymorphic microsatellite markers utilized genotype RILs employing Inclusive Composite Interval Mapping (ICIM). Especially eight identified four traits viz., plant height, root length, weight under stressed control conditions. Root Length (QRL-6-1 QRL-8-1) on chromosomes 6 8 PVEs 20.35% 10.29%, respectively situation. A QTL, QPH-4-1, also Chromosome 4 PVE 19.73% height stress. QGY-6-1 LOD value 7.95 22.14% Throughout growing seasons, two QTLs, QPH-4-1 QPH-8-1, Plant Height trait, 25.13% 3.21%, respectively. Three (QRL-3-1, QRL-6-1, QRL-11-1) as having highest score length. Two stable yield, (QGY-6-1 QGY-7-1) identified. It flanked RM19425 RM19521. These might prove be very beneficial breeding rice that resilient climate change, especially drought.

Genetic Diversity and Population Structure Analysis of Tree Peony (Paeonia Section Moutan DC.) Germplasm Using Sixteen Functional SSR Markers

Forests, Год журнала: 2023, Номер 14(10), С. 1945 - 1945

Опубликована: Сен. 25, 2023

Tree peony (Paeonia section Moutan DC.) is a traditional ornamental flower of China, which has thousands varieties with different colors and types after long history natural selection artificial breeding. However, tree perennial woody plant breeding, there are still significant challenges to accelerate the process genetic improvement important traits. In this study, total sixteen primer pairs high polymorphism good universality were selected from initial pool 115 SSR markers. The marker set was derived published papers on linkage map association analysis peony. Furthermore, we conducted diversity population structure 322 cultivars using molecular markers functional. These SSRs amplified 391 alleles, average number alleles 5.113 across all loci. Shannon’s information index, gene content 0.842, 0.532, 0.503 over loci, respectively. Population indicated that expected heterozygosity larger than observed heterozygosity, showing presence certain degree heterozygous deletion phenomenon. Japan had richest highest H (0.508) PIC (0.479) values. Zhongyuan showed greatest variation may be related its longstanding cultivation history. Moreover, STRUCTURE principal coordinate analyses individuals five populations grouped into two clusters. An variance demonstrated among populations. This research contribute sustainable management, conservation, utilization resources.

QTL discovery for resistance to black spot and cercospora leaf spot, and defoliation in two interconnected F1 bi-parental tetraploid garden rose populations

Frontiers in Plant Science, Год журнала: 2023, Номер 14

Опубликована: Июль 27, 2023

Garden roses are an economically important horticultural crop worldwide, and two major fungal pathogens, black spot (Diplocarpon rosae F.A. Wolf) cercospora leaf of rose (Rosisphaerella rosicola Pass.), affect both the health ornamental value plant. Most studies on disease resistance have focused diploid germplasm, little work has been performed resistance. With use newly developed software tools for autopolyploid genetics, interconnected tetraploid garden F1 populations (phenotyped over course 3 years) were used quantitative trait locus (QTL) analysis as well plant defoliation. QTLs mapped to linkage groups (LGs) 1-6. susceptibility found in LGs 1, 4, 5 defoliation 3, 5. The LG coincides with previously discovered Rdr4 inherited from Rosa L. 'Radbrite' (Brite Eyes™), common parent these mapping populations. This is first report any QTL resistance/susceptibility germplasm roses. A (Rdr4). was 1. These provide a genetic resource that will further knowledge base genetics more traits studied. Studying allow stacking various desirable traits.

Assessing and determining genetic diversity in rose species is a crucial step for conservation efforts, the establishment of core collection, development new varieties. This study represents first investigation among various at different ploidy levels Tunisia, with aim elucidating structure Rosa genus. It encompasses both spontaneous cultivated accessions, featuring local introduced recognized their adaptability, ornamental value, fragrance. A total 114 accessions representing eight were collected. Significant was assessed using seven SSR markers, yielding an average 21 alleles per locus PIC value ranging from 0.882 to 0.941. The results identified 343 phenotypic across primers, 72 primer RhE2b (LG6), 55 H10D03 (LG7), 54 RhB303 (LG2). One key finding that most perfumed (R. damascena Mill. R. centifolia L.) are distinct other indicating unique pool these roses. Another important Tunisian ‘Rose Ariana’ closely related commonly known as May’ Grasse, France. To clarify phylogeny this or subspecies, further molecular studies warranted. Additionally, nomenclature confusion between sempervirens L. canina northwestern region all wild correspond sempervirens.
