Cul-8770 and Cul-8772 had shown stable high yield potential over the seasons. These two cultures recorded high mean yield and lesser deviation from regression. BR-51-46-1 with its lower mean yield and higher deviation from regression, is not suited for general cultivation, especi.illy during kharif season. The added advantage of Cul-8770 and Cul-8772 is the good straw yield and red bold grains which are highly preferred in Kerala. All these attributes make Cul-8770 and Cul-8772 suited for release as varieties for general cultivation.ennullArticle
