Abstract/ Executive Summary:

The M₂ population having 25 or more number of pods was selected from the populations derived from Dacca-1 while that with 20 or more from PK-1 and BARI Chinabadam-8. Eighteen, six, eight and eleven progenies were selected from 150 Gy, 200 Gy, 250 Gy and 300 Gy dose irradiated populations of Dacca-1, respectively. In contrast, 15, 12, 01 and 02 progenies, respectively, from 150 Gy, 200 Gy, 250 Gy and 300 Gy doses irradiated populations of PK-1 were selected. But from BARI Chinabadam-8 only 02, 02 and 05 progenies were selected from 150, 200 and 250 Gy doses irradiated populations, respectively. These selected progenies will be further evaluated in M₃_,in next year.

Keywords: Groundnut, M2 generation, Selection

Location: BINA Farm, Mymensingh

Start Date:

End Date:

Program Area: Variety and Species

Commodity: Ground nut

Objectives:

To select high yielding mutants with early maturity, resistance to drought, salinity, high/low temperatures, major diseases and insect-pests having medium size pod

Methodology:

M₂ populations derived from irradiating the seeds of Dacca-1, PK-1 and BARI Chinabadam-8 with 150, 200, 250 and 300 Gy doses of gamma rays. The seeds of the M₂ populations were sown at 15 cm distances within rows of 20 cm apart following plant progeny rows at BINA Headquarters farm, Mymensingh. The plant progenies were derived from 150, 200, 250 and 300 Gy doses of gamma ray irradiations, respectively. Recommended doses of fertilizers were applied together with recommended cultural and intercultural practices. Data on plant height and pod number were recorded from randomly selected five competitive plants after harvest.

Achievement/Findings:

Eighteen, six, eight and eleven progenies were selected from 150 Gy, 200 Gy, 250 Gy and 300 Gy dose irradiated populations of Dacca-1, respectively. In contrast, 15, 12, 01 and 02 progenies, respectively, from 150 Gy, 200 Gy, 250 Gy and 300 Gy doses irradiated populations of PK-1 were selected. But from BARI Chinabadam-8 only 02, 02 and 05 progenies were selected from 150, 200 and 250 Gy doses irradiated populations, respectively.
