我省糯玉米地方品种主要分布在东部山区、半山区,以早熟为主,中熟次之。植株不繁茂,穗粒偏小。接种条件下抗病虫性较差。不论农艺性状或品质地区间均有差别。吉林半山区品种果穗偏长,穗行偏少,百粒重、单穗粒重较高,淀粉含量略高;通化地区品种穗行偏多,穗长偏短,百粒重、单穗粒重较低,蛋白质和赖氨酸含量相对较高。在营养成份含量间,油分和蛋白质变幅较宽,淀粉含量相对稳定。在蛋白质、油分、赖氮酸含量上,有趋于高营养指标含量的品种,也有农艺性状和营养成份含量表现具佳的品种,如白城黄粘等。这些变异及优良品种的存在,是我省开展品质育种的良好素材。在利用上,绝大部分品种不宜直接利用,通过定向选择、回交转育、外引种质导入等手段,改进农艺性状、增强抗病性、提高产量,可使我省糯质资源地方适应性强、品质较好等优点得以发挥。
Waxy corn varieties in our province are mainly distributed in the eastern mountainous areas, Mid-Levels, mainly to early maturity, followed in the cooked. Plants are not exuberant, spikelets are small. Inoculation conditions less pest resistance. Regardless of agronomic traits or quality of the region are different. The varieties of mid-mountainous area of Jilin had longer ears, fewer ears per plant, 100 seeds per plant, higher grain weight per plant, and slightly higher starch content. Lower, protein and lysine content is relatively high. In the nutrient content, oil and protein amplitude wider, relatively stable starch content. In terms of protein content, oil content and nitrogenous acid content, there are varieties that tend to have high nutritional content, but also varieties that have good agronomic traits and nutrient content, such as Baicheng Huangyin. These variations and the existence of fine varieties, is our province to carry out quality breeding good material. In utilization, the vast majority of varieties should not be used directly, through the choice of direction, backcrossing, introduction of foreign introduced species, etc., to improve agronomic traits, enhance disease resistance, increase yield, can make our province native resources of waxy adaptability Strong, good quality and other advantages to be played.
