我们于1984年开始引入汉中冬非,育苗分栽,建立选种田。采取的提纯复壮方法是:抗寒栽培,大株选种,严格选择,改良混合选择,多株母系留种法。 1.性状的选择汉中冬韭系抗寒品种,在选留种工作中,除了一般的经济性状选择外,重点注意对其抗寒性的选择。严格去除春韭和其他混杂植株。在提纯复壮过程中,我们多次采取了对入冬以后耐冻枯萎迟、假茎不倒伏、早春萌发早、生长快的单株标记,从严淘汰劣株。选种田采用单株稀植(15×10厘米),以利优良性的表现和选择,提高优株繁殖系数。选择前制订了品种的标准性状和定向选择的目标。品种的标准性状是: 株丛:生长健壮、直立,株高50厘米左右,单株功能叶9片,假茎长而粗,近圆形,当年单株分蘖4个以上。
We started in Hanzhong in winter in 1984, non-introduction, nursery sub-plant, the establishment of selected farming. To take the purification and rejuvenation methods are: cold cultivation, selection of large strains, strict selection, improved mixed selection, more strains of maternal leave method. 1. Trait selection Hanzhong winter leek cold-resistant varieties, in the selection of species to stay in the job, in addition to the general choice of economic traits, the focus on the choice of its cold resistance. Strict removal of spring leeks and other mixed plants. In the process of purification and rejuvenation, we have repeatedly adopted a single plant marker that is resistant to late freezing and withering after winter, false stems not lodging, early spring germination, and rapid growth, and severely eliminated bad strains. The selection of farming plant sparse planting (15 × 10 cm), in order to facilitate the performance and selection of excellent, improve superior coefficient of propagation. Prior to selection, a variety of standard traits and targeted selection goals were developed. The standard traits of varieties are: Strains: robust growth, erect, about 50 cm in height, 9 leaves per plant, long and coarse pseudostems, nearly circular, when more than 4 tillers per plant.
