Therefore, genetic studies of these two characters can support the effectiveness of Robusta coffee breeding program for obtaining superior planting materials. This study aimed to determine the diversity and frequency distribution of F1 generation on internode length and leaf size of Robusta coffee crosses. The study involved six groups of F1 progeny and their reciprocals (F1R) resulted from a cross of three parents, namely BP 961, Q 121, and BP 409. Each cross combination was planted with 41–49 progenies singly side by side in Kaliwining Experimental Station, Jember, Indonesia. The observed traits were internode length and leaf size. Analysis results of progeny variation distribution showed that most of the F1 and F1R progenies from intraspecific Robusta crosses had shorter branches than both parents in all combinations of crosses, even in BP 961 × BP 409 crosses. In addition, all F1 and F1R progenies had shorter internodes than both parents. More than 50% of the progeny of Q 121 × BP 409 and BP 961 × BP 409 crosses showed leaf length trait between parents. This indicates the absence of dominance of one parent in the progeny. Less than 20.9% of the progeny had a narrower leaf size than Q 121 parent. Most of the F1 and F1R crosses had a leaf width between both parents. The leaf length and leaf width traits were incomplete dominance or recessive, while the internodelength was overdominant. ","PeriodicalId":428979,"journal":{"name":"Pelita Perkebunan (a Coffee and Cocoa Research Journal)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127643589","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 use of selection criteria is very important in the selection process at the seedling phase, young plants and even mature plants in order to support the breeding process of resistant varieties. The aim of the study was to determine the characteristics of flush including flush color, stomata characters and duration of flush color change to green or towards mature leaves as one of the selection indicators for VSD resistance in cocoa. The research was conducted at Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute, Jember, Indonesia. Study of flush color and stomata characters was conducted using a randomized complete block design consisting of four cocoa genotypes with different levels of resistance, classified as resistant to VSD disease (Sulawesi 1, PNT 16) and as susceptible (BCL and BL 50). Each clone was repeated three times and each replication consisted of three plant samples. Flush color duration study was carried out on six cocoa genotypes as treatments, three genotypes with resistant to VSD (PNT 16, Scavina 12, Sulawesi 1) and three genotypes as susceptible to VSD (BL 50, BCL, Criollo 22). Each treatment was repeated three times and each replication consisted of three plant samples. The results showed that the resistant genotypes showed a tendency to have lower chlorophyll and anthocyanin content than the susceptible ones. The stomata character in the resistant genotypes was not different than the susceptible ones, however, the resistant genotype showed that the stomata density at flush tended to be lower. The duration of flush color change to mature leaves (green) in resistant genotypes was significantly faster than susceptible genotypes.","PeriodicalId":428979,"journal":{"name":"Pelita Perkebunan (a Coffee and Cocoa Research Journal)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121324355","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}

This research was conducted in randomized complete block design with three replications at Andungsari Experimental Station, East Java. The materials consisted of five parents of arabica coffee namely BP 542A(P1), P88(P2), S795(P3), HDT(P4), GEISHA(P5), and ten F1 hybrids as the offspring. The results showed that the narrow-sense heritability of leaf width was categorized as high. P3 and P5 varieties had the highest general combining ability (GCA) value for internode length, cluster number, and cherries number. These results indicated that both parental lines had potential as parents for the breeding program. The highest value of specific combining ability (SCA) for cherry size and leaf size was shown in crossing combination of P1×P3 and P2×P3.

Unfortunately, in Ghana, most cocoa-growing communities are the hub of illegal small-scale mining commonly known as galamsey. It is alleged that cocoa farmerssell their farmlands for galamsey; however, given that cocoa farming is the primary source of income for many households in rural Ghana. This research aimed at investigating the motivations for galamsey and how the practice impacts cocoa farming and the environment as well as farmer livelihood. The study was undertakenin Amansie West District in the Ashanti Region of Ghana where both cocoa farming and illegal mining operations coexist. The data for the study was collected using structured questionnaires. Cocoa farmers were purposively selected as respondents in two cocoa-growing communities. Data were obtained from 90 purposively sampled respondents through snowballing. Data collected were analyzed with Statistical Package for Social Scientist software. The results revealed that cocoa farmers face challenges due to galamsey such as; labour shortages, water pollution, competition for land amongst others. Also, cocoa farms, especially those downslope, get flooded whenever it rains as a result of uncovered galamsey pits near farms and cause black pod disease, early dropping of immature pods and stunted growth which ultimately reduce the output of cocoa farms. Farmers revealed that this affected their source of income adversely since the majority of them mainly depend on cocoa farming for their livelihood. They also reported a loss of green space and land degradation as some environmental hazards posed by galamsey. Information gathered from tenant farmers revealed that it is mostly landowners who give out their lands for galamsey. The major reasons that encourage galamsey were identified as higher short-term income, financial problems (40%) due to unemployment, and poor cocoa yield (26%). ","PeriodicalId":428979,"journal":{"name":"Pelita Perkebunan (a Coffee and Cocoa Research Journal)","volume":"519 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123127901","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 goal of this research is to create a temperature and pH monitoring system for the fermentation of cocoa beans using an android platform. The sensor must be able to measure temperature and pH during the fermentation process, and the sensor reading data must be displayed on the android display, according to the system design criteria.
