Heterosis Studies in Near IHomozygous Lines of Brinjal (Solanum melongena L.) for Yield and Yield Attributing Traits

摘要

Brinjal (Solanum melongena L.), an important member of family Solanaceae is an important crop in the tropical regions of world and being grown extensively. A number of cultivars are grown in India based on consumer preference for fruit color, size, shape and taste. The phenomenon of heterosis in plants is well known today and breeders exploit it for higher yield in crop plants and is an efficient approach for improvement of vegetable crops brinjal continues to be a choice of breeders for exploitationof heterosis due to hardy nature of crop, comparatively large size of flowers and large number of seeds in a single act of pollination. Hybrids offer opportunities for improvement in earliness, uniformity, productivity, quality, wider adaptability and rapid deployment of dominant genes for resistance to disease and pests. Information on the magnitude of heterosis in different cross combination is a basic requisite to assess for identifying crosses that exhibit high amount of exploitable heterosis. With these points in view, the present investigation was undertaken to study the heterosis in hybrids for plant growth, earliness, yield and its components.
