abstract

  • Germplasm accession ICML12 (PI537577; selected from bulk germplasm obtained from Mali) and ICML accessions 13, 14, 15 and 16 (PI537578 to PI537581; selected from bulk germplasm from Nigeria) are the first Pennisetum glaucum (P. americanum) accessions identified as having stable resistance to Sclerospora graminicola. During 1976-83, severity of infection on the selected accessions ranged from <1 to 7% compared with 42 to 69% on the susceptible standard NHB3. The accessions also showed 14-18% severity of infection by Puccinia penniseti (P. substriata var. penicillariae ) at Patancheru and Bharanisagar (India) during 1982-83, compared to 33% for the susceptible standard. At Patancheru the accessions were 1.5-2 m tall, produced 2-4 tillers, flowered 50-60 days after sowing and had panicles 22-40 cm long; 1000-seed weight ranged from 6.1 to 7.8 g
