AN ORANGE CAULIFLOWER HYBRID ‘JINYU 60’ WITH HIGH β-CAROTENE

Since nutritional quality of vegetables was increasingly considered to be an important marketing advantage, our cauliflower breeding research efforts were in recent years focused on providing new hybrids high in carotenoid concentration which plays an important role in human nutrition and health.
As a result, one F₁ hybrid with orange curds was bred.
It was crossbred by a cytoplasmatic male sterile line CMS92-60 as female parent and an inbred line 93-4 as male parent. 93-4 was an orange cauliflower mutant bearing low commercial value due to its too small and uncompacted curd.
CMS92-60 was a white cauliflower CMS line carrying the cytoplasmatic male sterile gene, which had good combining ability.
The results showed that this F₁ hybrid was improved in both nutritional value and commercial qualities compared to its parents.
It was determined that the content of -carotene in dry curd was 31.3 μg/g which was 10.8 times more than that of white cauliflower, and the contents of vitamin C, dietary fibre, protein, and mineral elements were nearly equivalent to those of white cauliflower.
Each head weighed 800-1000 grams on average, as the level of a commercial variety.
It is an early-mature variety, taking about 60 days from transplant to harvest.
This hybrid was consequently offered to the growers by the name of ‘Jinyu 60’. It is expected to have a positive market advantage in the future.
