Evaluation and identification of promising pearl millet germplasm for grain and fodder traits uri icon

abstract

  • Results are presented of experiments aiming to evaluate and characterize available germplasm lines, landraces and core collection lines of pearl millet and to exploit genetic variability so as to identify promising germplasm lines for metric traits for utilization in different breeding programmes and develop early and high-yielding potential hybrids/open-pollinated cultivars for grain and fodder in drier areas of India. The materials consisted of 2375 germplasm accessions, 180 landraces and 504 core collection lines. The germplasm lines and landraces were evaluated during the 2006 rainy season in Mandor, Jodhpur, Rajasthan, India. The accessions were sown in 22 blocks. Each block consisted of 120 accessions and 4 controls (J 2405, J 2340, NMP 24 and PP 29). The pearl millet core collection was also evaluated during the 2006 rainy season at 3 locations, i.e. AICPMIP, Mandor, Jodhpur; Agricultural Research Station, Rajasthan Agricultural University, Durgapura, Jaipur, Rajasthan; and Millet Research Station, Junagadh Agricultural University, Jamnagar, Gujarat. The core collection accessions were accommodated in 19 blocks. Each block consisted of 27 test accessions and 3 controls, namely IP 17862 (ICTP 8203), IP 22281 (Raj 171) (grain type) and IP 3616 (fodder type). After every 9 test accessions, one of the 3 controls was sown. Observations were recorded on morphological/metric traits, i.e. vigour, days to 50% flowering, days to maturity, plant height, productive tillers per plant, total tillers per plant, nodes per plant, sheath length, blade length and width, panicle exsertion, length, thickness and density, bristle length, 1000-grain weight, grain yield, grain yield potential, green fodder yield, green fodder yield potential, and overall plant aspect
