Zhanhong2 is a new Spanish type peanut, hybridization selected by Zhanjiang Agricul- tural Scientific Institute with female parentage （Zhanyou30）〈 Wengyuanzusi） Fs and male parentage CS41. It showed excellent characteristics such as high production and shelling rate, scarlet seed cloth- ing, high O/L rate, high resistant to rust and leaf spot, better drought and water logging tolerance but high susceptible to bacterial wilt. In Southern National Area peanuts test, it created the average dry pod productio creased by 5.25% n of 4130.55kg/ha in 2005 and 3561.6kg/ha in 2006 respectively. Its production in- and 3.47% compared with the control peanut Sanyou523, while the average pro- duction was 4211. 10kg/ha and 3923. 85kg/ha, which increased 9. 14% and 6. 11% in Guangdong province regional test in 2007 and 2008 respectively. With the main stem height of 48.2-53. 1cm, thebranch length of 50.1-56.4cm, branch number of 7.2-8.7, fruits per plant of 17.6-18.0, weight of 114.1-157.2g per 100 fruits, shelling rate of 67.3%-70.3%, it was certificated by Gurangdong province in July 2009 and the national southern cultivar identification in August the same year. Zhanyou2 was of good quality and extensively used new characteristic peanut, which make it has the broad market prospect. It can be planted in bacterial wilt free area in Guangdong province and other south- ern areas of China during the period of spring and autumn.
