Abstract: A comparative experiment of peanut(Arachis hypogaea L.) varieties was carried out in 2016, in which the average yield of 3 varieties was 4 290 kg/hm2. For the new line of Yichang black peanut,the entire growth period was 114 days, the plant was erect,the stem length was 58.1 cm,the branch number per plant was 8.3,the number of fruiting branches per plant was 6.8,and the average yield was 4 664 kg/hm2, which was 35.5% higher than Henan peanut No.22 and ranked the 2nd position. The yield per plant was 17.9 g, 500 g pod fruit weight was 482.6 g, in which the total kernel weight was 324.9 g and the full kernel weight was 304.5 g. The number of pods per plant, full pods per plant and blighted pods per plant were 18.5, 16.4 and 2.1, respectively. No germination and rotten fruit. As for Zhong peanut No.9, the average yield was 4 767 kg/hm2,38.5% higher than Henan peanut No.22,and ranked the first position. Its entire growth period was 113 days. The entire growth period of Henan peanut No.22 was 105 days with an average yield of 3 441 kg/hm2.

Key words: peanut (Arachis hypogaea L.); Yichang black peanut; comparative test of lines; average yield

花生(Arachis hypogaea L.)單株选择法简便易行,收效较快,是人们最常用的选育良种的有效方法之一[1]。宜昌黑花生系宜昌市农业技术推广中心2013年在夷陵区分乡镇普溪河村从黑花生地方品种中采用单株选择法经过系统选育而成的黑花生新品系(以下简称新品系)。2014年春播试种,单产3 375 kg/hm2;2015年夏播试种,单产4 200 kg/hm2。为鉴定该品系的特征特性、丰产性、适应性、抗逆性及利用价值,2016年在宜昌市进行了多点品种(系)比较试验。
