The possihlc breakthrough for developing bloat-free alfalfa(Medicago sativa L.)is to transfer the tannin gene into alfalfa by using biotechnology.This paper first reported the possibility and conditions of protoplast fusion between alfalfa and sainfoin (Onobrychis viciifolia Scop.),then we hope to transfer the tannin gene from sainfoin into alfalfa.The results proved that it was possible to fuse those two protoplasts.Through the genotypic selection,the cell lines which had similar cell cycle were selected and employed to isolate the protoplasts from those suspension cells.Both protoplasts of alfalfa and sainfoin were suspended in 0.1mMCaCl_20.6Mmannitol solution(pH5.6)with a total protoplast density of 3.6×10~5/ml(the densities of alfalfa and sainfoin protoplasts were 2.3×10~5/ml and 1.3×10~5/ml respectively).The heterokaryon frequencies were increased up to 26.7~ 40.9% under the electrical strengths of 1.00~1.25KV/cm with 1~3 pulses.The heterokaryons were able to divide 2~3 times,some 4 times and formed small colonies. However,the plating efficiency was very low and the colonies did not form callus.The re- sults suggested that in order to increase the plating efficiency of heterokaryon,the electrical strength should be lower than 1.25KV/cm,even 1.00KV/cm,with 1~2 pulses,thus elimi- nating the electrical damage to protoplasts.Meanwhile,the protoplast density for culture should be high and the culture conditions and methods should be improved.How to main- tain the cell division of heterokaryons and obtain a high plating efficiency would be the main problems in the future study.

无臌胀病苜蓿品种的育种计划的可能突破口,是利用生物技术把单宁基因导入到紫花苜蓿(Medicago sativa L.)中去。本文首次报道了紫花苜蓿与红豆草(Onobrychis viciifolia Scop.)原生质体融合的可能性和条件,进而将红豆草的单宁基因导入到苜蓿中去。本实验结果证明苜蓿与红豆草的原生质体融合是可能的,通过基因型选择,选择同步分裂的苜蓿和红豆草细胞系,从其悬浮培养细胞系中分离原生质体,将两者混合悬浮在0.1mMCaCl_2 0.6M 甘露醇溶液中(pH5.6),原生质体总密度为3.6×10~5/ml(苜蓿占2.3×10~5/ml,红豆草占1.3×10~5/ml),在1.00~1.25 KV/cm 电场强度下,脉冲次数1~3次,其异核融合细胞频率可提高到26.7~40.9%,并且其异核体仍能较好地分裂,可以分裂2~3次,个别分裂4次,形成小细胞团,但植板率很低,未能持续分裂形成愈伤组织。建议为了提高异核体的植板率,电场强度应低于1.25KV/cm,甚至低于1.00KV/cm,脉冲次数1~2次为宜,以减少电场对细胞的损害。同时提高原生质体培养密度,改良培养条件和方法。如何保证异核体持续分裂...

Wheat scab is a serious disease in the South of China,especially in the mid lower reaches of the Yangtze River.This paper highlights some of the significant progress made in screening resistant germplasm,inheritance of resistance,relationships between resistance and agronomic traits,mechanism of resistance,and breeding for wheat cultivars with resistance to scab in China.Although no immune materials are found in wheat and its relatives,the response to scab among varieties are significantly different.Scab resistance inherited quantitatively among resistant cultivars.Both numbers and chromosomal locations of resistant genes are different,which indicates that the diverse resistant genes can be recombined by intervarietal cross.There are no genetypic correlation between scab resistance and undesirable agronomic traits.Scab resistance correlated closely with activities of enzymes and contents of secondary metabolites as well as DON toxin which can be used as the physiological and biochemical indices in screening varieties resistant to scab.It will be helpful to further increase the efficiency of breeding for scab resistance by using biotechnology.

小麦赤霉病是中国南方麦区 ,尤其是长江中下游地区的一种严重病害。文章系统阐述了中国在小麦抗赤霉病种质资源筛选、抗性遗传、抗性与其它农艺性状的相关、抗性机制和抗病育种等方面的最新研究进展。尽管在小麦及其亲缘植物中还未发现免疫类型 ,但不同小麦品种间的抗性存在显著差异。小麦抗赤霉病性表现为数量性状的遗传特征。不同抗源之间抗病基因的数目和所涉及的染色体也不同 ,彼此可以杂交重组。抗性与农艺性状之间不一定存在必然的遗传联系。植物体内某些酶的活性、次生代谢物质的含量以及 DON毒素的含量与抗赤霉病性有密切联系 ,可作为筛选抗病品种的生理生化指标。通过各种育种途径都有可能育成抗病品种 ,而采用现代生物技术将有助于进一步提高小麦抗赤霉病育种的成效
