HYBRID VIGOUR EFFECT IN SORGHUM SELECTION

Hybrid vigour and maternal environment in mice

A combination of ovarian grafting and fostering was used to study the effects of preand postnatal maternal factors on adult behaviour. Inbred mice (BALB/c and C57BL/6) and F1 hybrids were compared to assess differential sensitivity to early maternal effects. In addition to the peculiar behavioural profile of BALB mice, results revealed the existence of a cognitive process in mice and confirmed ...

Hybrid Vigour? Genes, Genomics, and History

Is the gene 'special' for historians? What effects, if any, has the notion of the 'gene' had on our understanding of history? Certainly, there is a widespread public and professional perception that genetics and history are or should be in dialogue with each other in some way. But historians and geneticists view history and genetics very differently - and assume very different relationships bet...

Hybrid Performance of Sorghum Parental Lines Developed by Mass Selection and S1 Yield Testing

Small RNAs as important regulators for the hybrid vigour of super-hybrid rice

Heterosis is an important biological phenomenon; however, the role of small RNA (sRNA) in heterosis of hybrid rice remains poorly described. Here, we performed sRNA profiling of F1 super-hybrid rice LYP9 and its parents using high-throughput sequencing technology, and identified 355 distinct mature microRNAs and trans-acting small interfering RNAs, 69 of which were differentially expressed sRNA...

Hybrid Vigour of Behavioural Theories in the Agribusiness Research Domain. Is It Possible?

Motives, values and attitudes are key components of the decision-making process. Behavioural studies in agribusiness focus on using these three components to understand the decision-making processes of farmers (Morris & Potter 1995). Literature on three behavioural theories is reviewed with the aim of concluding if the theories can be combined for agribusiness research. Fishbein and Ajzen’s The...
