General Introduction Groundnut is an important grain legumeGroundnut is an important grain legume Is a good source of protein and high quality oilIs a good source of protein and high quality oil Groundnut is capable of fixing atmospheric Groundnut is capable of fixing atmospheric nitrogen which can benefit a succeeding crop Groundnut is generally drought tolerantGroundnut is generally drought tolerant There is a gradual shift from using groundnut as oil toward confectionery productsThere is a gradual shift from using groundnut as oil toward confectionery products

Confectionery Groundnut The target for confectionery groundnut is manufacturers of “Ntake Burger”, pebbles and those who sell roasted groundnut. They have sweet taste and good flavour The seeds are exceptionally big

Some Distinguishing Characteristics ICGV 87412ADEPA

ICGV ADEPA

Objective To evaluate the performance of confectionery groundnut lines and select adaptable lines for further testing on farmers’ fields

Materials and methods No. of entries: 16 Design: 4 x 4 lattice square with 3 replications Locations: 5 (Ejura, Wenchi, Kwadaso, Atebubu and Fumesua)

Data collected Days to 50% flowering Days to maturity Pod yield (kg/ha) Shelling percentage Pods per plant Plant height (cm) 100 seed weight (g) Plants/m2

Conclusion The lines have been subjected to multi- locational and on-farm evaluation Two of the lines have been proposed for release this year (ICGV98412 and ICGV 97049).

2.High Oil content groundnut evaluation Groundnut oil is a high quality edible oil It commands high price on the international market Groundnut seed with 50% or more oil content is regarded as having high oil content

Objective: To evaluate improved groundnut lines for high oil content and select those adapted to the local environment

Activities for 2012 Confectionery groundnut lines which have given consistently high yields will be tested on-farm Multi-locational testing of High oil groundnut and Aflatoxin resistant lines
