Abstract
Three hundred-eighty blast-resistant Tjere mas lines and the common Tjeres mas variety were grown in a preliminary trial in the 1963 dry season. On the basis of grain yield, earliness, and uniformity with respect to days-to-heading and plant height, 168 lines were selected for the following rainy-season planting.
Of the 168 lines planted during the rainy season, 31 outyielded significantly the check. Two headed significantly earlier than the check while 100 lines headed significantly later. Twenty-one lines were significantly taller and only three lines were shorter than the check. The lines had about the same tillering capacities. Most lines lodged at or before the heading stage. About two weeks after heading, all lines lodged completely.
Twenty lines were selected for further test on the bases of yielding capacity, earliness, shortness, and stiffness of straw and medium tillering capacity.
