Pigeonpea is important pulse crop of this country. The crop is extensively grown in Maharashtra, Uttar Pradesh, Madhya Pradesh, Karnataka, Andhra Pradesh and Gujarat. Seed is the most important input for crop production. Pathogen free healthy seed is urgently needed for desired plant populations and good harvest. Pigeonpea seed carry many mycoflora both in field as well as in storage as mould seed. The association of fungi adversely affects quality and health of the seeds. The seed samples of 19 varieties of pigeonpea were collected from various places in different agro-climatic zones for the detection of seed mycoflora associated with them. These samples were stored at room temperature (20-35°C). The presence of fungal flora associated with pigeonpea seed was detected by using the ISTA (1985) method. This involves the method - Dry seed inspection method. Discolouration of seed surface was observed in only 7 varieties viz., UPAS -120, MA – 97, Pant A-3, ICP-8862 Pusa- 9 and Bahar. Other 12 varieties show no symptoms on their seeds.In dry seed inspection light to dark discolouration within range of 1.0 to 7.0 was found in 8 varieties like UPAS-120, Pant A-3, MA-97, T-21, Pusa- 9, ICP-8862, C-11 and Bahar.

Abstract


Pigeonpea is important pulse crop of this country. The crop is extensively grown in Maharashtra, Uttar Pradesh, Madhya Pradesh, Karnataka, Andhra Pradesh and Gujarat. Seed is the most important input for crop production. Pathogen free healthy seed is urgently needed for desired plant populations and good harvest. Pigeonpea seed carry many mycoflora both in field as well as in storage as mould seed. The association of fungi adversely affects quality and health of the seeds. The seed samples of 19 varieties of pigeonpea were collected from various places in different agro-climatic zones for the detection of seed mycoflora associated with them. These samples were stored at room temperature (20-35°C). The presence of fungal flora associated with pigeonpea seed was detected by using the ISTA (1985) method. This involves the method - Dry seed inspection method. Discolouration of seed surface was observed in only 7 varieties viz., UPAS -120, MA – 97, Pant A-3, ICP-8862 Pusa- 9 and Bahar. Other 12 varieties show no symptoms on their seeds.In dry seed inspection light to dark discolouration within range of 1.0 to 7.0 was found in 8 varieties like UPAS-120, Pant A-3, MA-97, T-21, Pusa- 9, ICP-8862, C-11 and Bahar.
