'Universal' primers have been used to amplify the nontranscribed spacer (NTS) of the ribosomal 5S gene of avocado genotypes by the polymerase chain reaction (PCR). A rich size heterogeneity of NTSs of individual avocado genotypes was detected after high resolution polyacrylamide gel electrophoresis and silver staining. Specific sizes of NTS seem to be common for members of each horticultural ra...

Currently there are too few breeders to satisfy global demands and opportunities in the public and private sectors of developing and developed countries. In order to meet future needs, it is impo...

Horticultural crops are an important part of agriculture for food as well as nutritional security. However, several pests and diseases along with adverse abiotic environmental factors pose a severe threat to these crops by affecting their quality and productivity. This warrants the effective and accelerated breeding programs by utilizing innovative biotechnological tools that can tackle aforeme...

Observations by professionals can be utilized effectively to analyze the current understanding of the mechanisms by which horticultural activities bring about beneficial change. For purpose of discussion, these mechanisms can be divided into three categories: (a) Interaction, which is concerned with how people interact within the horticultural setting, (b) Action, which is concerned with person...
