Summary of the invention
The object of the present invention is to provide a kind of selection of functional form prescription rice variety.
Content of the present invention is a kind of selection of functional form formula rice kind, and this prescription rice variety is the mixed type kind, and the paddy of plantation grinds the rice that can contain black rice, purple rice, red rice, glutinous rice, 5 kinds of functional rices of giant embryo rice simultaneously.Its method is: through select for use in the present production the big and quality of popularizing area preferably rice varieties make recurrent parent; Respectively with black rice rice, purple rice rice, red rice rice, glutinous rice, giant embryo rice hybridization; In offspring and recurrent parent many generations, backcross, and seed selection economical character and recurrent parent are close, the proterties neat and consistent, stablizes and do not separate; And the NIL strain that has black rice, purple rice, red rice, glutinous rice, giant embryo rice proterties respectively, the production that mixes prescription rice by a certain percentage is with planting.
Technical scheme of the present invention is following:
(1) recurrent parent R (good standing grain early accounts for, good spoke accounts for, FR315 or bright extensive 86); With black rice rice (Qin rice No. 2), purple rice rice (inferior bigger purple rice), red rice rice (Anhui rice 129), glutinous rice (glutinous No. 6 of chaste tree) and giant embryo rice (MhgeR) hybridization, must hybridize F respectively
