tailieunhanh - Study on association of bio-physiological parameters with grain yield in sorghum genotypes under post flowering moisture stress conditions
A field experiment was conducted during rabi 2012-13 at research farm of Directorate of Sorghum Research, Rajendranagar, Hyderabad. The experiment was laid out in a split plot design, replicated thrice, with 10 Sorghum genotypes as main treatment (well watered and water stress conditions) and with 10 genotypes are sub treatments CRS 4, CRS 19, CRS 20, PEC 17, CSV 18, M 35-1, Phule chitra, Phule moulee, EP 57 and CRS 1). Photosynthetic rate and stomatal resistance at 15 and 30 DAF were positively and significantly correlated with grain yield while the transpiration rate at 15 and 30 DAF exhibited negative correlation with grain yield. SPAD chlorophyll meter reading (15 and 30 DAF) and chlorophyll content at 30 DAF had positively significant correlation with grain yield. | Study on association of bio-physiological parameters with grain yield in sorghum genotypes under post flowering moisture stress conditions
