Abstract

Sugarcane is a very useful industrial crop grown in India for its economic importance and various applications of products and byproduct to industry. It has a wide range of genetic diversity which provides a tremendous scope for genetic improvement of economic traits. An improvement in cane yield and quality characters in sugarcane crop is normally achieved by selecting the genotypes with desirable character combinations existing in nature or by hybridization. Hence, the information in a collection of some genotypes of sugarcane in order to formulate a sound breeding plan for its improvement has been reviewed here.

Abstract

An field experiment was conducted at Cotton Research Unit, Department of Agricultural Botany, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during Kharif 2007-2008 to estimate heterosis for seed cotton yield and fibre quality parameters. Twenty two hybrids were obtained by crossing two lines and eleven testers in a line × tester mating design. These parents and hybrids were grown in Randomized Block Design with three replications. The parents vs. hybrids indicated substantial amount of heterosis present in the population. Among 22 hybrids, hybrid AKH-0601 × BBP-1 exhibited highest economic heterosis (52.4%) for seed cotton yield which was followed by AKH-0601 × BBP-6 (47.5%) and AKH-0601 × BBPSPS-25 (45.9%). These hybrids also exhibited significant and desirable standard heterosis for yield components traits as well as for fibre quality parameters.
