The tiannongqingsi no . 1 hybrid ( sorghum bicolor s . sudan ense ) was introduced including its characteristics , cultural practices , use , feed value and development as well as application in the future 摘要介绍了天农青饲一号高粱苏丹草杂交种的特征特性、栽培要点、利用方式、饲用技术及开发应用前景。
After selected various high yielding and hybrid varieties , their nutrient uptake pattern , interaction among fertilizer , varieties and plant density should be investigated 近年来，我国选育出一批主要作物的高产品种和杂交种，应当研究它们的需肥特性，研究施肥与这些新品种及其种植密度等不同措施的关系。
Stability in early generation was first discovered in rice hybrid breeding , because it can fix genotype in early generation of hybrid , this probably made it real to cultivate a new kind of hybrid seed which could be planted for several generations 摘要早世代稳定现象首先在水稻杂交育种过程中发现，该现象可以早世代固定杂种基因型，这为培育可以多代利用的杂交种，奠定了一定的基础。
Mid - early matured variety , cylindrical shape with shiny pink skin , 30 - 40 cm in length , 5 - 8 cm in diameter , excellent fruit - setting , vigorous growth , suitable for growing in protected facilities and open field 中早熟、丰产、抗病长茄一代杂交种。植株生长势强，果实长棒形、果长30 - 40厘米、果实横茎5 - 8厘米、果皮亮紫红色、有光泽，商品性极好。适宜保护地及露地栽培，可在我国南北方种植。
Created or discovered and developed , plant varieties of any botanical genus and species , including clone , line , hybrid , and rootstock , irrespective of the method artificial or natural of their production , hereinafter referred to as arieties . ? p 已被创造或发现及开发的任何植物属别或种别，包括无性繁殖系clone品系line杂交种与根茎的植物品种，不论其生产方法天然或人工以下称为植物品种。
The germination of two seeds of hybrids was different form their parents . seeds of their parents were epigeal germination , but two seeds germination of hybrids which were derived form l davidii var . unicolor x ' yellow " and l davidii var 杂交种子萌发出现了不同于双亲的现象，亲本种子萌发都属于子叶出土型，而兰州百合黄色及兰州百合克得利亚中各有一粒种子的萌发，其子叶不生长，直接长出真叶。
In addition to acts effected in relation to the plant material of the protected variety itself , acts affected in relation to essentially derived varieties , other indistinct varieties and hybrid varieties dependent on the protected variety for their production , may also constitute infringements 以上的许可同时也可以应用在从属品种，包括实质衍生品种、不具明显可区分品种、需要用到受保护品种的杂交种等。
If you should be privileged to see a commercial bench of a candidate hybrid in bloom , you can learn more in half an hour about dominant and recessive characteristics , plant size and health , growth habit and vigor than you could in a year of attending orchid shows 如果你有机会看到商业展台上的开花的候选杂交种，你就可以在半个小时里就学到很多关于显性和隐性性状、植株大小与健康、生长习性和活力的知识，比你在一年中参观兰展学到的还多。
The karyotype of caragana microphylla lam can be espressed as 2n = 16 = 16m ( 4sat ) ; the chromosome number of c . intermedia kuang et h . c . fu is 2n = 18 . the karyotype of c . intermedia kuang et h . c . fu can be espressed as 2n = 18 = 16m ( 4sat ) + 2m ; the chromosome number of c . arborescens ( amm . ) lam is 2n = 20 . the karyotype of c . arborescens ( amm . ) lam can be espressed as 2n = 20 = 20m ( 4sat ) ; from the conclusion one and two , we can guess : the c . intermedia kuang et h . c . fu ' may be the hybrid or intermediary genve between caragana microphlla lam and c . arborescens ( amm ) lam , also may be have different haploid chromosome number ( 2 )可得出三种染色体核型：小叶锦鸡儿的染色体数为2n = 16 ，其核型公式为2n = 16 = 16m ( 4sat ) ；中间锦鸡儿的染色体数为2n = 18 ，其核型公式为2n = 18 = 16m ( 4sat ) + 2m ；树锦鸡儿的染色体数为2n = 20 ，其核型公式为2n = 20 = 20m ( 4sat ) ，结合形态学所得结论，可推测：中间锦鸡儿为小叶锦鸡儿和树锦鸡儿的中间类型或杂交种，也可能是具有递增染色体基数的不同种。
The results indicated that opposite maize had widespread heterosis like alternative maize ; yield advantage of opposite f1 ( alternative alternative ) was better than that of f1 ( opposite opposite ) and f1 ( alternative opposite or reverse ) ; general combining ability of yield characters was decreased by opposite characters transfer maize , but alternative maize with opposite genes has high general combining ability , so that on the opposite maize breeding , alternative inbred lines with different opposite genes can be parents for breeding hybrid lines ( alternative alternative ) and hybrid varieties with more seeds and high yield can be obtained 结果表明：对生玉米同互生玉米一样具有普遍的杂种优势，在产量性状上f1对生株优势互互组合大于对对组合和对互（互对）组合；对生性状的转育对产量性状的一般配合力有降低效应，而含有对生基因的互生玉米具有较高的一般配合力效应，因此，在对生玉米育种中可以利用含有不同对生基因的互生自交系作亲本来组配杂交组合（互互） ，从而获得较高的制种产量和高产的对生杂交种。
