Association between agro-morphological traits in common bean under organic fertilization management in Brazil

The objective of this work was to analyze the association between agro-morphological traits of the common bean cultivar “BRS Esplendor” under organic fertilization management. The experiment was implemented in the field, in a randomized block design, with three replications, in a split plot scheme, with two types of organic compounds (grass enriched with cattle manure and bean straw enriched with cattle...

Natural rubber (Hevea brasiliensis Müell.-Arg.) production, processing, and rubber wastes utilization: Challenges and prospects for economic diversification and sustainable development of Nigeria

Over 80% of Nigeria’s foreign exchange earnings come from the sales of crude petroleum. Nigeria has a landmass of 910,768 km2 with 38.97% arable, while 3.46% is suitable for the cultivation of permanent cash crops such as rubber, cocoa and palm trees. High-latex yields (3,000-3,500 kg dry natural rubber (NR)/ha/year) of Nigeria’s hybrid rubber seedlings is a preferred choice to most foreign species...

Variation of Parkia biglobosa morphological traits according to land use and agro-climatic zones in Southern Mali

A study was conducted in southern Mali to contribute to the domestication of Parkia biglobosa. Three agro climatic zones (North Sudanian “NS”, South Sudanian “SS” and North Guinean “NG”) and two stands (field and fallow) were concerned. Three plots of 0.25 ha each, were installed in each stand. Diameter at Breast Height (DBH), Total Height (TH) and Crown Diameter (CD) of adult trees...

Genetic characterization of Cape gooseberry (Physalis peruviana L.) accessions in selected counties in Kenya using SSR markers

Cape gooseberry (Physalis peruviana L.) is a neglected high potential crop, knowledge of the genetic diversity of the genotypes domesticated in Kenya is limited. To understand the genetic diversity and structure within and between Cape gooseberry germplasm, 70 accessions from six selected counties were analyzed using 15 pairs of highly polymorphic SSR primers. In this study, a total of 61 polymorphic SSR alleles were...

Genetic relationship and the occurrence of multiple gene resistance to coffee berry disease (Colletotrichum kahawae, Waller & Bridge) within selected Coffea arabica varieties in Kenya

The Coffee Berry Disease (CBD) epidemics destroy up to 100% of the crop on a susceptible variety. Resistance to CBD is conferred by the T-gene in Hibrido De Timor  (HDT), R-gene in Rume Sudan (RS), and k-gene in K7, which were assembled in resistance varieties Ruiru 11(R11) and Batian. This study aimed to evaluate the genetic relationship between R11 and Batian with their parents' HDT, RS,  SL8 and confirm...
