摘要:為篩選出適合隴東旱塬區(qū)種植的優(yōu)質(zhì)高產(chǎn)玉米品種,于2019年在甘肅慶陽(yáng)對(duì)12個(gè)玉米品種的農(nóng)藝性狀和抗逆性(倒伏率、對(duì)莖腐病的抗性)等進(jìn)行了田間比較。結(jié)果表明,供試12個(gè)玉米品種在當(dāng)?shù)鼐烧3墒欤跒?28~143 d。產(chǎn)量以先玉1321最高,為15 400.5 kg/hm2;新玉108次之,為14 785.5 kg/hm2;興貯88居第3位,為14 448.0 kg/hm2。在抗逆性方面,九圣禾2468、新玉108、陜單650、迪卡519、松科106、興貯88倒伏率均為0,表現(xiàn)出良好的抗倒伏性;九圣禾2468、新玉108和隴單9號(hào)對(duì)莖腐病表現(xiàn)出良好的抗性。從農(nóng)藝性狀和抗性等綜合考慮,新玉108、九圣禾2468和興貯88表現(xiàn)最佳,適宜在隴東旱塬區(qū)種植。

Abstract: To select premium and high yield maize variety for the Longdong rainfed plateau, agronomic traits and stress resistance performance(lodging rate and resistance to stem rot) of 12 maize varieties were evaluated in field. Results showed that 12 varieties could reach maturity, growth period was between 128 to 143 d. Highest average yield, 15 400.5 kg/ha, was obtained in Xianyu 1321, followed by Xinyu 108, 14 785.55 kg/ha, and Xingzhu 88, 14 448 kg/ha. In terms of stress resistance, lodging rates of Jiushenghe 2468, Xinyu 108, Shandan 650, Dika 519, Songke106 and Xingzhu 88 were all 0, which showed ideal performance in lodging resistance. Taken agronomic traits and stress resistance performance into consideration, Xinyu 108, Jiushenghe 2468 and Xingzhu 88 achieved optimum performance which could be considered suitable for the production in Longdong rainfed plateau.
Key words:Maize variety; Yield; Agronomic trait; Longdong rainfed plateau
