The aim was to identify G that combine high yield (YLD) with high ¿-carotene content (CC). In 2005 two trials were conducted in the Forest-Savannah Transition and the Deciduous Forest in RCBD. In 2006 one site (Costal Savannah) was added. Trials were harvested at 9 and 12 or 14 months after planting (MAP). Harvest data were collected for YLD and CC was determined by HPLC. Data were analyzed with MATMODEL 3.0; GGE biplot. Significant differences were found for G, E and GxE for the agronomic traits. Only the GxE of YLD was not significant. There were differences between G for CC per root, CC in root per plant and per hectare (ha) but no difference for ¿ carotene concentration (Bc). The best G for CC was 01\/1417 followed by 01\/1371 and 01\/1368. The differences between E were highly significant for all ¿-carotene traits. The highest values of Bc were recorded at 9 MAP. From this study 01\/1368 and 01\/1417 with high dry YLD and high CC were proposed for on farm and release against vitamin A deficiency in Ghana.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783848436019\"\u003e\u003ch3\u003eCassava as source of beta carotene to overcome vitamine A deficiency in Ghana\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783848436019","offer_id":39489996095581,"sku":"9783848436019","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/c04415d5-c43c-40a6-b06f-0b29ac3585c9.jpg?v=1777010614","url":"https:\/\/shop.autorenwelt.de\/products\/genotype-by-environment-on-ss-carotene-and-yield-of-yellow-root-cassava-von-norbert-maroya","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
