The study used six tropical maize inbred lines from CTMMYT as parents of a 6×6 half diallel cross and evaluated under low and high levels of N application to determine the types,relative magnitudes of gene effects and heritability.Field experiments were conducted at University of Philippines during the 1997 wet and 1997-1998 dry seasons.Under low N condition,there were significant additive genetic differences in the base population for grain yield,number of rows per ear,100 kernel weight,ear length,number...

The study used six tropical maize inbred lines from CTMMYT as parents of a 6×6 half diallel cross and evaluated under low and high levels of N application to determine the types,relative magnitudes of gene effects and heritability.Field experiments were conducted at University of Philippines during the 1997 wet and 1997-1998 dry seasons.Under low N condition,there were significant additive genetic differences in the base population for grain yield,number of rows per ear,100 kernel weight,ear length,number of ears per plant,number of green leaves below ear,anthesis silking interval,ear leaf area,and shoot dry weight,and highly significant additive differences for plant height.The characters which have higher narrow sense heritability are plant height,ear length,ear leaf area,100 kernel weight,number of rows per ear,and number of green leaves under ear.The results suggested the possibility of solving N deficiency problem by breeding technology.

采用 6个国际玉米小麦改良中心的热带玉米自交系为亲本 ,按Griffing方法 2组配成双列杂交 ,在高氮和低氮条件下对各主要性状进行鉴定 ,并估算其遗传参数。结果表明 ,从高N到低N ,籽粒产量降低程度最大 ,降减系数 (RI)达0 4845 ,与叶绿素含量降低程度几乎一致。自交系间和杂交组合间在产量的降解系数上有明显的遗传差异。低氮条件下 ,籽粒产量、穗行数、百粒重、穗长、单株穗数、穗位以下绿叶数、雌雄开花差期、穗位叶面积、地上部干重和株高有显著的加性遗传方差 ,同时 ,籽粒产量、穗长、穗粗、雌雄开花差期、叶绿素含量、地上部干重、行粒数、百粒重、单株穗数和株高有显著的显性遗传方差。狭义遗传力较高的性状包括株高、穗长、穗位叶面积、百粒重、穗行数和穗位以下绿叶数。研究显示 ,通过轮回选择在自交系中积累较多有利基因 ,组配优良杂交组合来提高玉米耐低氮的能力是可能的。

Thirty combinations were made between 3 inbred lines and corresponding improved inbred lines involving tropical maize germplasm as female parents and 5 inbred lines from other places as male parents with NC Ⅱ mating design to analyze the combining abilities of 10 agronomic characters.The results indicated that:① inbred line"4S"had higher general combining ability(GCA) in 100 grain weight and yield per plant,and the combinations made by 4S as female parent had better stability in yield;②"75" and "249"...

以江苏沿江地区农业科学研究所培育的 3个自交系及其导入热带种质的 3个改良系为被测系 ,以 5个外引系为测验种 ,按NCⅡ设计配制 30个组合 ,分析 10种农艺性状的配合力。结果表明 :自交系“4S”在百粒重和单株产量上的一般配合力较高 ,用其作母本配制的组合具有较好的稳产性 ,“75”和“2 49”在矮化育种上具有较高的利用价值 ;导入热带种质的改良系与对应自交系相比 ,株高、穗位高的一般配合力显著增加 ,穗粗和轴粗的一般配合力亦有增加的趋势 ,其余性状则随自交系遗传背景不同而异 ;多数性状同时受父母本一般配合力和组合特殊配合力的作用 ,因此高产组合的选配必须同时兼顾两种配合力的选择

The effect of long photo-period on the maize germplasm was conducted with the material comes from tropical,subtropical,temperate and highland maize genotypes,using the method of artificial enlarged light period.The results showed that:the germplasm of different eco_type showed the same trend as the photo_period enlarged from 13.3 Hr to 17.5 Hr.That is,compared with the normal photo_period conditions,plant high(Ph),ear high (Eh)increased,anthesis day(Ad)and leaf senescence delayed,the anthesis_silking interval (ASI)enlarged,ear per plant(Epp)decreased and the total leaf number(Lf)increased.The photo sensistive index of different germplasm in an increasing order is:temperate maizemaizemaize <tropical maize.The study had some guiding meaning for the introduction and improvement of maize germplasm for the temperate maize.

以典型的热带、亚热带、温带和高原玉米种质为材料 ,采用人工延长光照的方法 ,观测了各类种质对长光周期的反应。结果表明 ,随光周期由 13 3h延长至 17 5h ,不同生态型玉米种质表现出相同的变化趋势 ,即 :株高、穗位高增加 ,雄穗开花期及叶片衰老期延迟 ,雌雄穗开花间隔加长 ,单株穗数降低 ,总叶片数增多。不同生态类型种质对长光的敏感性表现为温带玉米 <高原玉米 <亚热带玉米 <热带玉米。该研究对温带地区玉米种质的引进及改良具有指导意义
