Criteria for early selection in tulip breeding


, : Criteria for early selection in tulip breeding. Acta Horticulturae (47): 179-185

Comparison between small bulblets and adult bulbs of well-known cvs has led to provisional criteria for early selection which are being tested in seedling populations. The annual increase in the main bulb diameter together with the offset number during the last year of the juvenile phase have proved to be efficient pre-selection criteria for bulb production. Early selection for production had no adverse effect on forcing ability.

The major pigment in red peel of several apple cvs was confirmed as cyanidin 3-galactoside; minor pigments identified were cyanidin 3-glucoside, 3-arabinoside and 3-xyloside and the acylated derivatives of all 4 glycosides. Only one anthocyanin wa...

Extracapsular extraction of the lens (ECE) by the mini-nuc method was done on 3 dogs with cataract (Romania). Results showed that ECE surgery of cataracts by the mini-nuc method was very complex, requiring proper instrumentation and adequate surgi...

The expression of cytochrome P45 (CYP) 1a1 and other drug-metabolizing enzymes is controlled by the aryl hydrocarbon receptor (AhR), which is activated by dioxin-type inducers leading to transcriptional induction of target genes. Here, we show tha...
