"It has sprouted! All have sprouted!" Yan Longan's excitement burst into tears, and the big rock that was pressing in his heart could be regarded as falling to the ground
.

In February 1971, more than 50 agricultural science and technology personnel from 13 provinces (cities, autonomous regions) including Jiangxi, Hunan, Guangdong, Guangxi, and Fujian, came to Yuan Longping’s Hainan Island base-Nanhong Farm, began to study with class, and participated in the whole country.
Research on the selection and breeding of rice male sterile lines
.

Yan Longan, 33, is one of them

With these 48 seeds, Yan Longan returned to his hometown of Pingxiang, Jiangxi
.

In March of Yangchun, 48 seeds were planted with the hope of researchers, but the seeds were planted for a whole week without any movement

Early in the morning of the 8th day, he and his assistant Li Ruguang rushed into the test field, and found a grain out of the mud with an uneasy mood.
After squeezing it, it was still hard! This shows that the seeds are good
.

They hurriedly dug out all the remaining 47 seeds one by one carefully

Where is the problem? Yan Longan consulted around and thought behind closed doors, and finally found the crux of the problem: the hybrid offspring seeds with wild relatives may have a longer dormancy period and must be subjected to temperature changes to break the dormancy period
.

So he consulted local farmers and used cow dung piles to prime the sprouts, but it still didn't work

With the help of these germinated seeds, in the winter of 1972, Yan Longan led the team to finally bred "Erjiuai 4A" and "Zhenshan 97A" and began to provide sterile seeds to the whole country
.

He also became the first person in the first batch of "wild defeat" sterile line breeders in China
