Evaluation of Advanced Medium Maturing Rosette Resistant Lines of Groundnuts (Arachis hypogaea L.) for Adaptation to a Southern Guinea Savanna Ecology

Abstract

Fifteen medium maturing rosette-resistant groundnut accessions collected from I>A>R. germplasm pool were evaluated for their adaptation to a southern guinea savanna ecology of Kwara State using a local cultivar as a reference crop.  The investigation consisted both potted planting and field studies in a randomized complete block design replicated three times in each case.

      The result showed variable but comparable performance with the reference cultivar in terms of flowering and maturity time, haulm weight and seed yield.  However, nearly all the improved varieties showed evidence of adaptability prospects in the alien environment.  It is suggested that further evaluation would enhance yield stability of the elite groundnut accessions in the ecological zone
