Can you also eat Cantonese Longan in the Mid -Autumn Festival?This new variety is worth looking forward to

A few days ago, at the on -site observation of the new variety "Crispy (SZ52)" of late maturity high -quality longan lychee in late maturity, Liu Chengming, a professor of South China Agricultural University and the modern agricultural industry technology system of Guangdong Province, an expert from Liu Chengming He and the team have been cultivated in the world's first long -eye and litchi hybridization new varieties in the world for 15 years. They are late mature, fruitful, strong growth, strong cold resistance, and wide adaptability. significance.

Longan and lychee belong to the genus Longan and lychee in classification. "Crispy" is a new variety selected by Shi Ji Longan as the mother, and the Zi Niang Xili lychee as the parent. This variety has some advantages of Shijia Longan and Zi Niang Xili Litchi. Its flesh is tender and crispy, completely residue, with a sugar degree of 20-24%. Liu Chengming said.

It is understood that "crispy" is still a longan variety, but its flesh is very tender, which is similar to lychee. In addition, the cracks of the "crispy" peel are obvious, which is bumpy. This is also the characteristic of lychee. Essence In addition, "crispy" also has the important characteristics of more low temperature resistance and strong cold resistance.

Liu Chengming said that as early as the 1990s, he began research on the integration of native body integration of fruit tree breeding, but he had not obtained the ideal result. "So I thought about changing my mind, just make a sexual hybrid between the two genus." He continued to test and seek technical means to get hybrid seeds. "This process is very difficult and complicated, and the success rate is only a few thousandths, but in the end we still do it."

With the support of related technologies, the team began to choose different longan and litchi varieties for hybridization. After continuous trial and error, in 2007, it successfully obtained the first batch of mixed seedlings. These small seedlings also have the genetic material of the mother book (Shi Yan Longan) and the father's (Zi Niang Xili). Between messenger. After many years of cultivation test, it was not until 2014 that SZ52 single strains were finally selected. In 2017, the team started regional trials. At present, "crispy" has performed well at Chaozhou, Zhanjiang, Guangzhou Conghua, Qingyuan Lianzhou, Sichuan Luzhou and Chongqing Yongchuan.

Huang Xuming, a professor at South China Agricultural University and chief expert of Guangdong Longan Innovation Team, said that the current structure of longan varieties is relatively single. "Crispy" can move the longan production area to the north, expand the production area, and extend the production period. In the future, the Mid -Autumn Festival can also eat Guangdong longan.
