During 2017 to 2018, a fruit rot of peach (Prunus persica) occurred in Hunan Province of China. The symptoms showed as soft, brown water-soaked lesions with offwhite sporulation, in some cases, on the fruit surface, extending in the flesh, which was decayed. The fungus was isolated and identified as Fusarium solani based on morphological characteristics and molecular identification using the internal transcribed spacer (ITS), a portion of the translation elongation factor-1 alpha (EF-1α) and beta-tubulin gene sequences. The pathogenicity of the isolated F. solani was confirmed. To our knowledge, this is the first report of F. solani causing fruit rot of peach in Hunan, China.

Bollwarm has been a serious problem in cotton production in China since the 1990th. To breed transgenic pest-resistant cotton variety is one of the most economic measures. Bivalent insect-resistant Bt + CpTI gene transgenic cotton variety possesses stronger pest resistance compared with Bt cotton. CCRI 41 is an insect-resistant gene transgenic cotton variety bred by Cotton Research Institute, Chinese Academy of Agricultural Sciences. A bivalent insect-resistant Bt+CpTI gene was transformed into a high-performance conventional cotton variety, and stable and high-performance transgenic lines were selected using stress-resistance screening and molecular assistant selection strategies. It was the first national released bivalent insect-resistant transgenic cotton variety in China. The cumulative extension acreage of CCRI 41 has reached 3 million ha extensive popularization of CCRI 41 since 2002 in 6 provinces in Yellow River Valley and has reaped economic benefits of 4.5 billion RMB yuan in total. These scientific achievements won the 2009 State Science and Technology Awards of China (2nd prize).
