2 beach is a good field, and the rice flowers in the saline alkali land are fragrant. The rice varieties with salt tolerance and high yield were bred, and 100 million mu of high yield seawater rice was popularized.

the new dream of the old man,
is expected to be realized as scheduled?
"18 tons per hectare, we have the technical route"
"18 tons per hectare, we already have the technical route." Yuan Longping, Deng Qiyun, the core breeder of the team, is confident that the answer will be given to the ScienceDaily Daily reporter.
Deng Qiyun, the cultivator of the successful varieties of the second, three and four stage targets of our super rice "Y two you 1", "Y two you 2" and "Y two you 900". "Based on the utilization of Intersubspecific heterosis between Indica and subspecies, the modeling of dynamic ideal plant type of rice, and molecular marker breeding, we have obtained two potential varieties that are expected to achieve a target of 18 tons per hectare."
one is the "Y two excellent 957" passed by the state last year. It is "Y two excellent 1", "Y two excellent 2" and "Y two excellent 900" three varieties "half sister" brothers. The yield of rice varieties is high, and the quality of rice can reach the national standard 2 grade quality rice quality standard.
, however, he is more optimistic about the latest cultivation and is expected to be tried by the middle and lower reaches of the Yangtze River "Wang two excellent 950". "Through molecular marker breeding technology, we introduced" big grain gene "into its parents. Through the parent transformation, the 1000 seed weight of the cultivar increased by 2-3 grams. The highest value of this index increased by more than 10% over the previous super rice varieties. Therefore, the yield potential is greater than that of 'Y two - you 957'. Combined with our "four matching" comprehensive technical system, this year is expected to achieve 18 tons per hectare target in small area cultivation.
