Dentro de la raza Chalqueño maíz se pueden reconocer diferentes grupos genéticos regionales (GGR) principalmente con base en su origen geográfico y características grano. El objetivo esta investigación fue determinar el comportamiento agronómico esos GGR heterosis, así como las relaciones entre heterosis divergencia genética. Cuarenta nueve poblaciones nativas sobresalientes Chalqueño, agrupada...

T IS not my purpose in this paper to present or to discuss the actual basic I causes or the fundamental mechanisms which bring about the increased size, the excessive kinetic energy, the increased productiveness, resistance to disease or to unfavorable conditions of the environment, the “stimulating effects of hybridity,” the so-called “hybrid vigor” of English writers and “Luxurieren” of many ...

Crosses between different mink lines from 3 Danish mink farms that use different breeding strategies were studied to estimate heterosis and variance components for litter size. The study was designed to analyze crosses between lines of the same color type, between different color types, and between animals originating from different farms. Effect of heterosis, color type, and variance component...

The present investigation has been undertaken in sweet corn to carry out the combining ability analysis and to estimate heterosis of yield and yield contributing characters. Eight divergent parents were selected and crossed in diallel fashion excluding reciprocals during kharif, 2010. The resulting 28 crosses along with parents and a standard check Sugar 75 and Madhuri were evaluated in Randomi...
