Quality, quantity, and cost of feed resources available for beef production vary from one region of the country to another and within regions, depending upon climatic factors and natural resources available in specific production situations. Diversity among breeds can be exploited by crossbreeding to optimize performance levels and to match genetic resources with the climatic environment, feed ...

Crossbreeding has been the breeding method of choice for several species in plants and livestock. In plants, the main reason for crossbreeding is to exploit heterosis effects which can be maximized via the use of highly inbred parental strains. In livestock, notably in poultry and swine, positional effects of pure-bred parents of crosses are well known and hence crossbreeding systems are set up...

Line × tester design was employed to evaluate nine parents of Corchorus olitorius for their combining ability and heterosis seedling traits under normal drought conditions. Analysis variance revealed significant differences among the crosses. Under conditions, root length, fresh dry weight roots, volume, shoot exhibited contributions line interaction hybrid. Among parents, JRO 3690 OIN 970 disp...

Aims: The aim of this study is to estimate heterosis, heterobeltiosis and dominance effect on yield, total soluble solid dry matter capia type red pepper.Methods Results: In 11 pepper parents 47 hybrids obtained from crosses these were used as materials. Heterosis in fresh fruit yield ranged -48.23 80.68. highest heterosis recorded for 209 YKB (80.68%), 239 (60.35%), 225 (56.97%) 195 (55.30%), ...
