Comparative analysis of phenotypic characterization of Kenya and Pacific Islands tarogen germplasm collections Colocasia esculenta L. (Schott)
Palapala, Valerie; Netondo, G; Akwee, Edome Peter (2015-08-21)Fifty accessions of taro germplasm collections Colocasia esculenta L. Received: 15 November, 2014 (Schott) were collected from Kenya and Pacific Islands tarogen germplasm collections. Twenty five accessions of Kenyan ... -
Effect of wheat bran supplementation with fresh and composted agricultural wastes on the growth of Kenyan native wood ear mushrooms [Auricularia auricula (L. ex Hook.) Underw.]
Palapala, Valerie; Otieno, C. A.; Onyango, B. O. (2015-08-21)Nutrient supplements and agricultural wastes used for mushroom cultivation are important in improving establishment and production of mushrooms. Agricultural wastes such as sawdust, grass, sugarcane bagasse, wheat straw ... -
Evaluation of Polymorphism Generated By Single Sequence Repeat Markers in Selected Taro Populations
Palapala, Valerie; Akwee, Edome Peter (Journal of Medical and Biological Science Research, 2016-08-03)Genetic structure of Kenya and Secretariat of Pacific Community’s Tarogen taro germplasm was investigated. Fifty cultivars were evaluated using six SSR primer combinations. Significant polymorphic variations within the ... -
Farmers’ perceptions on adoption of Bambara nut production as a food security crop in Kakamega county, Kenya
Palapala, Valerie (2015-08-21)This study was conducted between April and December 2011 to examine perception of smallholder farmers in four districts of Kakamega County, Kenya in adoption of Bambara nut production as food security crop. The study was ... -
Gender Influence on Farmer’s Level of Involvement in Utilization and Conservation of Bambara Groundnut
Palapala, Valerie; Oyugi, Millicent; Amudavi, David (2015-08-21)Aims: To understand the role of gender on Bambara groundnut cultivation with respect to levels of farmers’ involvement in utilization and conservation in Western Kenya. Study Design: A questionnaire was administered to ... -
Genetic diversity analysis of Kenyan taro [Colocasia esculenta (L.) Schott] accessions using SSR markers
Palapala, Valerie; Akwee, Edome Peter (Sky Journal of Agricultural Research, 2016-07-08)Six SSR primer pairs were used to characterize 25 taro genotypes of Kenya. A total of 30 polymorphic alleles were generated. The number of alleles per locus ranged from 1 to 6 alleles, with an average of 3.0425 alleles ... -
Genetic structure and diversity of East African taro [Colocasia esculenta (L.) Schott]
Palapala, Valerie; Macharia, Mercy Wairimu; Runo, Steven Maina; Muchugi, Alice Njeri (2015-08-21)Taro [Colocasia esculenta (L) Schott] is mainly produced in Africa by small holder farmers and plays an important role in the livelihood of millions of poor people in less developed countries. The genetic diversity of ... -
