谷子是抗旱而适应性较强的作物,这是它在干旱地区种植稳产的基础,但要获得较高的产量必须选育良种。选育适种于中部干旱区的良种,必须针对十年九旱,土地瘠薄,谷子生产水平低而不稳的特点,以早熟,高产,抗逆性强(主要是抗旱、耐瘠),适应性广为育种目标,并兼顾中晚熟性。 1.高产:以选育单秆大穗型为主。要求株高1.5米左右,穗长24—30厘米,千粒重4克左右,出谷率80％以上,株型
Millet is a drought-resistant and adaptable crop, which is the basis for its stable planting in arid areas, but must be bred for higher yields. Breeding suitable arid areas in the middle of the species, must be ten years of drought, infertile land, low and unstable millet production characteristics, with early maturity, high yield, strong resistance (mainly drought, barren), adaptation Sex widely breeding objectives, and take into account the late maturity. 1. High yield: the main single-spike breeding style. Requires about 1.5 meters plant height, spike length 24-30 cm, 1000 g weight about 4 grams, the valley rate of 80% or more, plant type
