Varietal Assessment of Crops Sown in 1988 and 1989
Evaluation for Early Maturity
In the screening trials on early-maturing varieties, four lines, ICGV 86053, ICGV 86016,
ICGV 86103, and ICGV 86117 were retained out of the 24 breeding lines of early-maturing
varieties from ICRISAT, as they were stable and high-yielding.
Evaluation for Confectionery Groundnut
In the screening trials on confectionery groundnut, four varieties, ICGV 82028, ICGV 86504,
ICGV 87151, and ICGV 86556 were retained, out of 23 varieties for their sweet taste and their
seed size.
Assessment for Resistance to Leaf Diseases
Of the 35 varieties assessed during crop years 1988 and 1989, ICGV 87165, ICGV 87175,
ICGV 87176 were found to be resistant to late leaf spot, rust, and tolerant of early leaf spot.
These varieties also had better yields and hulling rates than the control.
Determination of Optimum Sowing Densities and Dose of NPK
Determining Optimum Sowing Densities. A local spanish-type variety called "Maressi"
was used. A density of 166 000 plants ha -1 gave the best pod yield (3.17 t ha -1 ).
Determining the Optimum Dose of NPK.
optimum dose of NPK for groundnut crops.
Trials were also conducted to determine the
In conclusion, since the program was carried out in conjunction with eminent researchers
from other African countries and international institutions, some steps could be omitted in the
research in order to get straight to the adaptation trials.
