Genetic components of variation in sorghum [Sorghum bicolor (L.) Moench]

Abstract

The genetic components of variance for ten elite lines of sorghum (ICSV 700, ICSV 705, IS 18551, GJ 39, GJ 40, CSV 15. GSSV 149, SR 670, Malwan and IS 2312) and their 45 F(s derived through diallel (excluding reciprocals) were studied over two environments i.e., kharif 1996 and 1997 at Sorghum Research Station, GAU, Deesa. The experiments were laid out in a randomized block design with three replications in both the years. Each entry was represented by a single row with 45 x 15 cm, spacing. Five plants from each row of parents and F1's were randomly selected to record five characters namely days to 50% flowering, plant height (cm), dry fodder yield/plant (g) and 1000 grain weight (g). The genetic components of variance were worked out as per Jinks and Hayman [1] and Hayman [2].
