  an autotetraploid
graecum is an autotetraploid, the hybrid (2n=4x=90) is an amphidiploid, the microspore-derived plant (2n=45) is a polyhaploid and the hybrid (2n=3x=66) is a sesquidiploid.
      
Group I contained all of the autotetraploid and diploid indica maintainer lines and an autotetraploid and its original diploid indica male sterile lines.
      
We interpret this and other differences between salmonids and catostomids as reflecting an autotetraploid origin for salmonids and an allotetraploid origin for catostomids.
      
This kale was shown cytologically to be an autotetraploid (2n=4x=36, CCCC), thus probably possessing a double set of the shoot-forming gene(s).
      
However, conclusions drawn for these species are not always applicable to crops like potato, which is an autotetraploid, highly heterozygous, vegetatively propagated species.

This study was primarily attempted to optimize the electrofusion parameters using protoplasts isolated from cell suspension cultures of “Page” tangelo (Citrus reticulata Blanco×C.paradisi Macf) and mesophyll protoplasts of rough lemon(Citrus jambhiri Lush) as fusion partners. It was shown that the binuclear heterokaryons frequency reached 15% with the following parameters: alternate current (AC) 125 V/cm, AC time 60 s, direct current (DC) 1250 V/cm, DC pulse width 50 μs, DC pulse interval 0.5 s, No. of...

This study was primarily attempted to optimize the electrofusion parameters using protoplasts isolated from cell suspension cultures of “Page” tangelo (Citrus reticulata Blanco×C.paradisi Macf) and mesophyll protoplasts of rough lemon(Citrus jambhiri Lush) as fusion partners. It was shown that the binuclear heterokaryons frequency reached 15% with the following parameters: alternate current (AC) 125 V/cm, AC time 60 s, direct current (DC) 1250 V/cm, DC pulse width 50 μs, DC pulse interval 0.5 s, No. of DC pulse 3. Considering the fact that different types of protoplasts have different specific weights, higher frequency of the binuclear heterokaryons was obtained by controlling the centrifugation time after fusion. The fusion products regenerated into plantlets after 3 to 4 months of culture. Chromosome counting of the root tips and morphological observation of the regenerants verified that 78% were tetraploids and the rest were diploids with the leaf morphology of mesophyll parent. Peroxidase (POX) isozyme and RAPD analysis indicated that interspecific somatic hybrids were obtained and an autotetraploid plant of mesophyll parent type was also verified.

以“Page”橘柚(CitrusreticulataBlanco×C.paradisiMacf)胚性悬浮系原生质体和粗柠檬(C.jambhiriLush)叶肉原生质体为融合试材,摸索了适合柑橘的电融合参数。研究表明,在AC(交变电场)125V/cm、DC(直流脉冲)1250V/cm、AC作用时间60s、DC脉冲时间50μs、DC脉冲个数为3、DC脉冲间隔为0.5s时融合率较高,双核异核体率可以达到15%以上。利用不同类型原生质体比重的不同,融合后通过控制离心时间,可以收集到更高比例的双核异核体。融合产物经培养,3~4个月再生小植株。染色体计数结合形态学观察表明,再生的150株小植株中78%为四倍体,其余为二倍体叶肉亲本再生类型。再生植株经过氧化物酶同工酶及RAPD分析,表明得到了体细胞杂种,还证明获得了1株叶肉亲本同源四倍体再生类型。

An autotetraploid non heading Chinese cabbage Zaoyoudong( Brassica campestris ssp.chinensis Makino)was developed from its diploid sibling plants with green stalk,through colchicine treatment on shoot tips.The autotetraploid was used in the cross with autotetraploid cultivars Shuzhouqing(high quality)and their F 1 was used in an additive cross with autotetraploid cultivar Reyou No 2(heat resistance)for selection of self incompatible lines,based on morphological and physiological...

An autotetraploid non heading Chinese cabbage Zaoyoudong( Brassica campestris ssp.chinensis Makino)was developed from its diploid sibling plants with green stalk,through colchicine treatment on shoot tips.The autotetraploid was used in the cross with autotetraploid cultivars Shuzhouqing(high quality)and their F 1 was used in an additive cross with autotetraploid cultivar Reyou No 2(heat resistance)for selection of self incompatible lines,based on morphological and physiological characters.After repeated selfing and selection,self incompatible lines G SI and E SI were developed and used as parent to produce F 1 hybrid cultivar Shuyou No 1,which is characterized by green stalk,high quality and heat resistance.
