Nepenthes usually produce lower traps near the base of the plant, and upper pitchers form a loop in the tendril, allowing it to wrap around the nearby plant. Pitcher plants, being insectivorous plants, can grow in nitrogen-deficient soils. In the Riau Archipelago Province, the intense land conversion to establish ecotourism in national parks disturbed the pitcher plant habitat, even though the pitcher plants have great potential as ornamental plants. Therefore, for in situ conservation, the existing endemic flora may benefit tourist attractions to support local ecotourism efforts. Based on the above discussion, the presented study aimed to characterize the pitcher plants’ diversity and analyze the relationship among its species using morphological markers in the islands of Bintan, Karimun, and Lingga, Indonesia. Based on the collection and identified pitcher plants, the study discovered that the genus Nepenthes comprises 25 accessions belonging to six different species, i.e., N. gracilis, N. × trichocarpa, N. reinwardtiana, N. ampullaria, N. rafflesiana, and N. × hookeriana. The cluster analysis grouped two main clusters that have a similarity coefficient of 31%–97% based on morphological characteristics among Bintan, Karimun, and Lingga accessions. However, the cluster constructions were more on the traits’ similarity than locality based. For principal component analysis (PCA), 19 morphological traits can benefit as diagnostic features to distinguish the pitcher groups. The study revealed that pitcher plants have diverse phenotypic plasticity in the Riau Archipelago, which is experiencing land conversion for tourism activities. The pitcher plants diversity has the genetic potential for ornamental plants development and is a biological wealth that requires conservation for research, tourism activities, and future generations.","PeriodicalId":21328,"journal":{"name":"Sabrao Journal of Breeding and Genetics","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46877451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hydrogenation technology process includes various equipment and materials, i.e., equipment for hydrogenation, laboratory flow reactor, autoclave for hydrogenation on powder nickel-copper catalyst, hydrogenation catalysts, and selection of alloy stationary catalysts and their structure. The hydrogenation process includes selecting alloy nickelaluminum catalyst promoters, measuring the viscosity of hydrogenated fat, using static catalysts as forcontacts, kinetic regularities of cotton oil hydrogenation with new modifications of nickel-copperaluminum alloy promoted catalysts, and reception of food hydrogenated fat by consecutive hydrogenation of cotton oil on powder and stationary catalysts. Modifying immobile nickel-copperaluminum alloy catalysts also evolved with the addition of vanadium, rhodium, and palladium in the hydrogenation process. The cotton oil pre-contact hydrogenation on stationary and powder nickelcopper catalysts is a novel development. It ensures an increase in the physiological and nutritional value of margarine products based on hydrogenated food fat. Studying the influence of technological regimes of cotton oil hydrogenation on new modifications of stationary nickel-copper-aluminum promoted catalysts commenced. The obtained results established the technological parameters for acquiring food and confectionery salons by combining stationary and suspended catalysts.

They contain various nutrients, such as, anthocyanins, carotene, minerals, and vitamins. New varieties with high mineral contents in leaves need development to increase the leaves’ quality as vegetables. This study aimed to identify and characterize cassava genotypes of the MV10 generation resulting from gammaray- induced mutations based on the leaves' morphology, growth characteristics, and mineral contents, using two cultivars and 10 cassava genotypes. All genotypes planted in a randomized complete block design had three replications. The leaf's morphology and mineral contents underwent scrutiny on the third to fifth leaf below the apical shoot. The mineral content analysis used the Atomic Absorption Spectrophotometry method. Data analysis comprised the ANOVA test and descriptive analysis. This study revealed petiole length, leaf lobe length, and leaf lobe width were significantly different between genotypes at four months after planting (MAP). However, no meaningful difference showed for the plant height, stem diameter, and number of leaves among genotypes. In general, the leaf morphology consisted of purplish green apical leaves with present pubescence; the shape of the central leaflet is lanceolate; the petiole color is reddish to greenish; leaves are dark green with five to seven leaf lobes; leaf veins are reddish-green; smooth lobe margins; and horizontal petiole orientation. The genotypes affect mineral contents, as the genotype with the highest Mg contents was G6-2-15-5-3, and the one with the highest Zn contents was G2D1-422. Fe contents showed more variations between genotypes, and no genotype showed consistently high Fe contents. This research produced promising genotypes for Mg or Zn contents in leaves for future cassava varieties for vegetable production.","PeriodicalId":21328,"journal":{"name":"Sabrao Journal of Breeding and Genetics","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42438197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, evaluating grain yield, provitamin A content and other agronomic traits of eight lines, four testers, and their 32 hybrids occurred during the 2015-2016 and 2016-2017 cropping seasons. The results showed that genetic parameters related to combining ability and heterosis among various F1 hybrids influenced all the studied traits except plant height. The parental genotypes P6 and P10 were suitable for improving 100-kernel weight, grain yield, stature at ear insertion, and provitamin A content. The parental genotypes P7, P4, and P2 were promising for provitamin A content, while the parental genotype P3 was leading for grain yield. Five hybrids (P10 × P5, P10 × P6, P10 × P7, P10 × P8, and P11 × P5) showed distinction as the best specific combinations for improving productivity and provitamin A content. The F1 hybrid P10 × P6 with desirable specific combining ability revealed that it is helpful as the best combination in producing double and triple hybrids with the highest yield and provitamin A potential. Crosses P10 × P5 and P11 × P5 can serve as the best cross combinations for grain yield, while hybrids P10 × P7 and P10 × P8 showed promising for provitamin A content.

Results concluded that fine-fiber cotton cultivars Marvarid, Surkhan-14, and Guzor can benefit as initial breeding material in selecting high-yielding cotton cultivars.","PeriodicalId":21328,"journal":{"name":"Sabrao Journal of Breeding and Genetics","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43109698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
