FINGERPRINTING OF SWEETPOTATO GERMPLASM USING AFLP, RAPD, AND SAMPL ANALYSIS

The ability to improve productivity and agronomic traits of sweetpotato through breeding programs depends on assessing the genetic variation of their germplasm and genetic relationship to other genotypes. In addition, studying genetic diversity supports the conservation of genetic resources. In this study, three different DNA-based markers, random amplification of polymorphic …

Diversity analysis of sweet potato (Ipomoea batatas [L.] Lam) germplasm from Burkina Faso using morphological and simple sequence repeats markers

Collecting and characterizing plant material is a basic component of crop improvement, and diversity has long been seen as vital for rational management and use of crops. Thirty (30) morphological characters and thirty (30) simple sequence repeat (SSR) markers were used to assess the diversity among 112 sweet potato (Ipomoea batatas …

Genetic diversity in sweetpotato [Ipomoea batatas (L.) Lam.] in relationship to geographic sources as assessed with RAPD markers

Available evidence shows that sweetpotato originated from either Central or South American lowlands with subsequent dispersal to North America, Europe, Africa, Asia and the pacific islands. A total of 71 polymorphic RAPD molecular markers were used to assess the genetic relationships amongst 74 sweetpotato varieties originating from a total of …

PROCEDURES FOR THE EVALUATION AND ANALYSIS OF SWEETPOTATO TRIALS

Breeding programs involve large investments of time and money, but can pay very large returns on investment in the form of improved varieties which benefit farmers, societies and the environment. International breeding efforts involving multiple partners and targeting regionally important constraints have great potential for efficiently and rapidly achieving impact. …

ON-FARM PARTICIPATORY VARIETY TESTING — PROTOCOLS (May, 2012)

On-farm trials are an effective way to improve client-orientation of breeding programs by formalizing farmer involvement in the variety testing process. They can also be an important first step in variety dissemination, since data from on-farm trials are usually required for official varietal release, and farmers will be keen to …
