generation mean analysis was carried out to estimate the nature andmagnitude of gene effects for sugar yield and its component traits in sweet sorghum[sorghum bicolor (l.) moench. six basic generations, namely p1, p2, f1, f2,bc1p1, bc1p2 of four crosses involving seven diverse parents were evaluated inrainy 2009. the mean performance of the f1 in all the crosses indicated dominantgene effect fo...

Crosses between plants from different populations may result in heterosis or outbreeding depression. However, despite its importance for conservation, little is known about the spatial scale over which these effects may arise. To investigate the consequences of between-population crosses at two distinct spatial scales, we conducted reciprocal crosses between four populations from two regions in...

self-incompatibility in almond and prunus species is an important genetic trait that prevents self-fertilization. self-incompatibility in almond is controlled gametophytically by the multiallelic s-locus. this study was done in order to identification and preliminary selection of self-compatible progenies resulted from controlled crosses in almond using specific primer sff-sfr.some important mo...
