6种鲜食彩色花生品种比较试验

Comparative Experiment on 6 Colorful Fresh-eating Peanut Varieties

[目的]为彩色花生产品的开发奠定基础。[方法]以彩色花生品种开白二号、YA03-5、豫黑、YS03-1-1、9686-8、豫紫一号为试材,以宿迁推广的高产大果品种为对照,通过随机区组排列的田间试验筛选出适宜江苏省栽培的优良彩色花生品种。[结果]9686-8的荚果产量最高,为4 363.5 kg/hm2,其次是开白二号,其荚果产量为4 282.5 kg/hm2,分别比对照增产13.2%和7.8%;豫紫一号的荚果产量最低,为3 715.5 kg/hm2。YS03-1-1感病毒病,中抗叶斑病,抗茎腐病。豫黑中抗茎腐病、叶斑病,YA03-5中抗叶斑病、病毒病。其他品种抗病性强。YA03-5的抗涝性弱。开白二号、9686-8、YS03-1-1、YA03-5、豫黑和豫紫一号的百仁重分别为69.40、72.50、55.70、67.50、65.18和70.66 g,开白二号、9686-8、YA03-5和豫黑的出仁率分别为63.1%、70.3%、54.0%和59.2%。[结论]该研究为彩色花生品种的选择和种植提供了理论依据。

[Objective] The purpose was to lay a foundation for the development of colorful peanut products. [Method] With colorful peanut varieties Kaibai 2, YA03-5, Yuhei, YS03-1-1,9686-8 and Yuzi 1 as tested materials, with high-yield and big-fruit variety popularized in Su- qian as CK, the good colorful peanut varieties suitable for cultivating in Jiangsu Province were screened out through the field experiment with randomized block arrangement. [ Result] The pod yield of 9686-8 was highest, being 4 363.5 kg/hm2 ; that of Kaibai 2 was secondary, being 4 282.5 kg/hmz ; both of them were increased by 13.2% and 7.8% resp. in comparison with that of CK. The pod yield of Yuzi 1 was lowest, being 3 715.5 kg/hm2. YS03-1-1 was susceptible to virus disease, moderately resistant to leaf spot and resistant to stem rot. Yuhei was mod- erately resistant to stem rot and leaf spot. YA03-5 was moderately resistant to leaf spot and virus disease. The disease resistances of the other varieties were strong. The waterlogging resistance of YA03-5 was weak. The lO0-kernel weights of Kaibai 2, 9686-8, YS03-1-1, YA03-5, Yuhei and Yuzi 1 were 69.40, 72.50, 55.70, 67.50, 65.18 and 70.66 g resp. The kernel rates of Kalbai 2, 9686-8, YA03-5 and Yuhei were 63.1% , 70.3% , 54.0% and 59.2% resp. [ Conclusion ] The research provided theoretical basis for the selection and planting of color- ful peanut varieties.
