摘要:
胡萝卜雄性不育材料,在胡萝卜育种中具有重要作用。本文描述了一种从武汉市洪山区野生胡萝卜材料中获得的野生瓣化型胡萝卜雄性不育材料(‘武野-不育’,简称‘Wuye-BY’)的特征。该野生瓣化型雄性不育胡萝卜特征在于:无明显膨大的肉质根,嫩茎、叶片及其叶柄深绿色,几乎无毛,无花瓣和花药。花萼数量8-10个,花丝数量为0-2个,染色体数目为2n=18。双悬果顶端及其花丝顶端,具有大量的蜜液,能接受栽培胡萝卜花粉。杂交F1代的根大小、根重,胡萝卜素、总糖和维生素C含量,具有明显优势。

Abstract:
Male sterility played important roles in carrot breeding. In this study, a wild petaloid male-sterile carrot (named: ‘Wuye-BY’) was obtained from the wild carrot in Hongshan district of Wuhan city, China. The wild petaloid male-sterile carrot was not obvious fleshy taproots. Its tender stems, leaf blades and petioles were dark green without pubescence, petal and anther. The number of calyxes is 8-10 and the number of filaments is 0-2. The chromosome number of the male sterility is 2n=18. The top of mericarps and filaments contained a large amount of nectars. The male sterility can freely receive the pollen of cultivated carrots. The hybrid F1 had obvious advantages in root size, root weight, carotene, total sugar and vitamin C content.
Key words:  wild carrot  petaloid male-sterile  ‘Wuye-BY’  heterosis  characteristics
