摘要
[目的]开展耐旱花生品种筛选试验,以筛选优质高产耐旱花生新品种,为其在临沂丘陵薄地花生种植区推广提供依据。[方法]参试花生品种共8个,分别为花育36号、开农49、山花9号、豫花9719、花育22、山花11号、临花5号、临花6号,以花育25为对照。[结果]参试品种中山花9号和花育36号表现较好。其中,山花9号生育期比对照晚1 d,株高最矮,分枝数、结果枝数最少,饱果率最高,出米率也最高,子仁产量为3 457.5 kg/hm2,比对照增产10.6%,居第1位,抗旱性强,抗涝性中等,综合抗性好;花育36号生育期与对照相同,株高比较低,分枝数、结果枝数和对照差不多,子仁产量为3 295.5 kg/hm2,比对照增产5.4%,居第2位,抗旱性、抗涝性中等,综合表现好。[结论]山花9号、花育36号综合性状良好,生育期适宜,可作为临沂丘陵薄地花生种植区域耐旱品种进行推广种植。
[ Objective ] The aim was to carry out the screening experiment of peanut cultivars with resistance to drought to screen out new pea- nut cuhivars with good quality, high yield and resistance to drought, and then to provide a basis for their promotion in peanut planting area of upland with barren soil in Linyi. [ Method] The trial peanut cultivars were eight, namely Huayu No. 36, Kainong 49, Shanhua No. 9, Yuhua 9719, Huayu 22, Shanhua No. 11, Linhua No. 5, Linhua No. 6, resp. , taking Huayu 25 as control. [Result] In all trial cultivars, Shan- hua No. 9 and Huayu No. 36 showed better. Shanhua No. 9＇ s growth period was later 1 day than control, its plant height was the shortest, its branch number and fruit number were both the least, its full-pod rate and ratio of shelled peanut were both the highest, its seed kernel yield was 3 457.5 kg/hm2 which higher 10.6% than that of control, ranked the first, it had strong resistance to drought and medium resistance to flood, so its comprehensive resistance was good; Huayu No. 36＇s growth period was same as control, its plant height was shorter, its branch number and fruit number were both same as control, its seed kernel yield was 3 295.5 kg/hm2 which higher 5.4% than that of control, ranked the second, it had medium resistance to drought and flood, so its comprehensive resistance was good. [ Conclusion] Shanhua No. 9 and Hua- yu No. 36 have good comprehensive traits, and their growth period are suitable, so they can be promote and plant in peanut planting area of upland with barren soil in Linyi as peanut with resistance to drought.
