Heterosis study for yield and yield attributes in sorghum [Sorghum bicolor (L.) Moench]

Author(s): Ajitsinh B Rajput, Rahulkumar R Vaid and Vinodbhai S Chaudhary
Abstract: The present investigation was carried out with a view to study the per se performance and magnitude of heterosis using L × T analysis. The experimental material consisted of eight parents (3 females and 5 males) and their resultant fifteen crosses with standard check CSH-25 were evaluated in a randomized block design with three replications. at Main Sorghum Research Station, Navsari Agricultural University, Athwa farm, Surat during Kharif-2019. In the present investigation, a variable degree of heterosis was observed for almost all the characters. Total eight promising hybrids viz., GJ-38 × GNJ-1, IS-5476 × ICSV-17044, GJ-42 × GNJ-1, GJ-38 × ICSV-17044, GJ-42 × ICSV-17041, IS-5476 × GNJ-1, GJ-38 × ICSV-17041 and IS-5476 × ICSV-17041 were identified with high heterosis and heterobeltiosis and high per se performance for grain yield and significant useful heterosis for some other important traits. From the top-ranking hybrids for grain yield, Cross combinations GJ-38 × GNJ-1, IS-5476 × ICSV-17044, GJ-42 × GNJ-1 and GJ-38 × ICSV-17044 depicted significant standard heterosis for panicle length. This hybrid can be used in further breeding programme for high yield with long panicle.
