Directional selection in advance generation progenies of sorghum Kulkarni Narendra, Narayana D., Murty K. N. Andhra Pradesh Agricultural University, Rajendranagar, Hyderabad-500 030, India Summary Twenty-four advanced generation F5 and F6 progenies were studied for grain yield and yield components along with their parents. Considerable variability was present between F5 progenies on which selection can operate. The F6 progenies were superior to F5 progenies, their parents and improved varieties for grain yield and yield components except number of primary branches. Particularly the progeny 643 of IS 6928 × CSV-5 cross was early, dwarf, and highest yielding. Regression of F6 and F5 suggested that F5 itself was good indicator of F5 performance for plant height, 50% flowering, number of primary branches and 1000 grain weight. Based on within and between family variations and regression analysis, it is concluded that while between family selection would be effective for plant height, 50% flowering and number of primary branches, individual plant selection within family should be followed for grain yield and number of secondary branches in sorghum.
