Sistemas de selección en trigo (Triticum aestivum L.) en ambientes alternados e in situ.
(Colegio de Postgraduados, 1997)
En México, el éxito del mejoramiento genético del trigo se debe a que se han obtenido variedades mejoradas de alta estabilidad y rendimiento mediante el sistema alternado Toluca-Yaqui (T-Y), propuesto y desarrollado en México por Borlaug. Este trabajo tuvo como objetivos estudiar: la influencia del fotoperíodo, radiación y temperatura, en la ocurrencia del período vegetativo, reproductivo y de llenado de grano del trigo ...
Input productivity in agriculture on the north coast of Colombia
(Universidad de la Florida, 1971)
The allocation of capital within the agricultural sector 1 of a developing nation is, or should be, of primary concern to those who are formulating or implementing development policy. The critical nature of the use of capital is in large part created by its shortage as an input in the development process, and by the widespread demand and need for capital inputs to escape from what is now commonly called "traditional" ...

Testing a lineage exclusion strategy for breeding rice resistant to blast disease
(Purdue University, 2001)
Rice blast, the disease caused by the fungus Pyricularia grisea Sacc. (teleomorph Magnaporthe grisea (Hebert) Barr.), has challenged plant breeding programs in their search for durable resistance. Rapid resistance breakdowns are commonly observed and are attributed to the frequent appearance of new pathotypes or to poor screening of the pathogen population prior to release. Recent population studies of the rice blast ...
