Research results of the seasonal influence on the ability of production of hybrid rice seed F1 combinations TH7-2 in Thanh Hoa
To actively produce rice seeds in the locality, Vietnamese scientists studied and created many new hybrid rice combinations, including hybrid rice combinations of two lines: Vietnam hybrid rice 20, TH3-3, TH3-4, TH3 -5, TH7-2, HYT8 and etc. These combinations can give high quality, short growth period, the area is increasingly expanding.

For hybrid rice, quality of hybrid grain F1 plays an important role in the production of goods. In Thanh Hoa, a hybrid rice of the two lines is capable of intensive production as TH7-2, using temperature - sensitive male sterility.

Therefore, Mr. Nguyen Ba Thong from Hong Duc University conducted a study to determine the appropriate season for the production of hybrid rice seeds F1 combination TH7-2 of crop conditions in Thanh Hoa.

Sowing experiments of mother rice lines (T7S) and father rice lines (R2) in 5 seasons, each season separated 7 days, start sowing the maternal rice line of season 1 from June 3.

Experiment was arranged in randomized complete block (RCB), repeated 3 times, plot area  is 22m2 (under parental rice lines: 2,75m x 8,0m) and etc.
