为澄清新种质QR-001对粗缩病的抗性遗传特性，将抗玉米粗缩病的新种质QR-001与5个感病自交系分别杂交和回交后，创造了5个F2杂交群体和5个BC1回交群体。初步研究了QR-001的抗性遗传规律，结果表明，新种质QR-001对粗缩病的抗性符合由2对隐性基因共同控制的遗传规律，并指出了该种质在育种实践中的应用策略。
為澄清新種質QR-001對粗縮病的抗性遺傳特性，將抗玉米粗縮病的新種質QR-001與5箇感病自交繫分彆雜交和迴交後，創造瞭5箇F2雜交群體和5箇BC1迴交群體。初步研究瞭QR-001的抗性遺傳規律，結果錶明，新種質QR-001對粗縮病的抗性符閤由2對隱性基因共同控製的遺傳規律，併指齣瞭該種質在育種實踐中的應用策略。
위징청신충질QR-001대조축병적항성유전특성，장항옥미조축병적신충질QR-001여5개감병자교계분별잡교화회교후，창조료5개F2잡교군체화5개BC1회교군체。초보연구료QR-001적항성유전규률，결과표명，신충질QR-001대조축병적항성부합유2대은성기인공동공제적유전규률，병지출료해충질재육충실천중적응용책략。
In order to clarify the inherited characteristics of QR-001,the population of five BC1 and five F2 were constructed after one new resistant germplasm , QR-001 , was crossed and backcrossed with five susceptible inbred lines.The genetic rule of the resistance to maize rough dwarf disease of QR-001 was primarily studied .The results showed that the resistance to maize rough dwarf disease of QR-001 was controlled by two sets of recessive genes .The application strategy of the new resistant germplasm was pointed out too .
