Inheritance of Grain Shattering in Rie

Abstract

Introduction.Shedding or shattering of grain is an important economic character in rice. In cultivated rices this causes a serious loss during harvest and the loss is estimated to very according to the locality and the varieties.from as low a figure as 5% up to 30%.The firmnes with which the ripe grain is attatch -ed to the rachis varies widely in different varieties.Wild rices exhibit this character to the maximum extent,the grains here falling away at the slightest impact of wind,even before they are fully ripe.In certain provinces where the cultivate rices get hybridised with wild rices through natural agencies the problem of shedding become a serious one.Some of the progenies of these croses look for all practical purpose like the cultivated types but have the badly shattering character of the wild rice in them.Since it is not usually possible to identify them and eliminate them in the early stages,they form a permanent source of deterioration of the crop.Bhalerao(1930)surveyed Mallnad tract of the Southern Division in the Bombay Presidency and has suggested remedial measures against these 'Gonaga'or cultivated rices showing this wild character.
