ABSTRACT

The aim of this study was to determine the correlation between seed yield and some quantitative traits. This was performed by exposing the seeds of landraces pigeon pea to gamma radiation at Centre for Radiotherapy and Oncology Department, ABUTH, Zaria at doses of 0(control), 50, 100, 150 and 200Gy. These seeds were further treated with sodium azide (NaN₃) concentrations at 0.00, 0.01, 0.02, 0.03 and 0.04% SA, giving a total of 25 treatments. The growth parameters were recorded at 4, 8, 12, 16 and 20 Weeks after Planting (WAP). A positive correlation was observed between seed yield and many other quantitative traits like number of pods per plants, mean number of seeds per pod, and protein content.
