摘要
2005年至2009年,黑龙江省共审定推广玉米品种183个,其中普通玉米品种159个,占86.9%,其次是青贮和粘玉米品种;中晚熟和中熟玉米品种129个,占70.4%。科研院所和大专院校育成品种77个,占42.1%;民营种业育成品种106个,占57.9%。该期间审定推广的玉米品种与1986～2004年间审定推广的品种相比,粒重与出子率有较大增长,产量进一步提高;粗淀粉含量提高了1.14%,但粗蛋白质含量、粗脂肪含量和赖氨酸含量有不同程度的下降。本文探讨了黑龙江省玉米育种面临的问题。
From 2005 to 2009,183 maize varieties had been bred and commercialized in Heilongjiang province. Among them, 159 are ordinary varieties,accounting for 86.9% of the total varieties developed, following by ensiling and glutinous varieties. In addition, 129 are medium-late and medium varieties, accounting for 70.4%. Furthermore,42.1% of the varieties was developed by public institutions, whereas 57.8% by private sectors. Compared with varieties commercialized from 1986 to 2004,100 - kenels weight and yield seeds ratio of all the varieties had been increased with the kernel component of crude starch increased by 1.14% ,while the crude protein, crude fat and lysine decreased.
