EFFECT OF GAMMA RAYS ON YIELD AND YIELD ATTRIBUTES OF LARGE SEEDED CHICKPEA (Pages : 19 - 24)

A pot experiment was conducted at the Plant Breeding Division of Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh during November to February. Fresh seed of two genotypes (Binasola-2 & CPM-834) of chickpea were irradiated with ten different doses of gamma ray including a control viz. 0, 100, 200, 300, 400, 500, 600, 700, 800 and 900 Gy from 60 Co source. The seeds were sown in pots and yield and yield attributes were studied in M1 generation. All the characters showed significantly different effect for the different doses. Flowering and maturity occurred earlier in treated population than the control. Due to 700 Gy dose the number of branches were recorded the highest. The number of pods/plant and seeds/pod reduced due to higher doses of gamma rays. But 300 Gy and 100 Gy caused the increase of 100 seed weight and seed yield/plant than control, respectively. Protein percentage of M1 seeds was higher in 400 Gy treated plants. Download
