Selection of high yielding wheat lines from irradiated composites

In order to obtain high grain yielding lines of wheat (Triticum aestivum L.) from two irradiated composites derived from the variaty Salamanca S75, 191 plants in generation Msub9, were selected by their high values in tillering, spike and grain size. The best three lines yielded 62, 59 and 56% more than Salamanca S75, respectively, due to gains in tillering, grain number and weight per spike, and in grain size and weight. The same performance was obtained in the last four experiments, but in less proportion. Grain quality analysis of two lines was similar to that of Salamanca S75 Para obtener lineas de trigo (Triticum aestivum L.) de alto rendimiento de grano a partir de 2 compuestos irradiados procedentes de Salamanca S75, en la generacion Msub9 se seleccionaron las 191 plantas con el mayor numero de tallos, tamano de espiga y de grano. Las 3 lineas de mayor rendimiento superaron a Salamanca S75 en 62, 59 y 56%, por tener mayor numero de tallos, numero y peso de granos por espiga y tamano y peso de grano. La superioridad de estas lineas sobre Salamanca S75 tambien se manifesto, aunque en menor proorcion, en los otros 4 experimentos. La calidad industrial del grano de 2 de las 3 lineas fue similar a Salamanca S75
