The anthers of six varieties and thirty-nine hybrids of O. sativa subsp. Shien were cultured in vitro. The callus has been obtained in five varieties and thirty-five hybrids. Mean frequency of callus induced from anther was 2.18%. Green plantlets or shoots have successfully been obtained in three varieties and eleven hybrids. The present paper reports primarily the role of basic medium and supplemental constituents in callus induced from anther and in differentiation of root and shoot.1. The best medium inducing callus from anther of rice has been found to be Miller + 2,4-D 2mg/L + yeast extract 1000mg/L + kinet in 1mg/L + indol-zylasetic acid (1AA) 2mg/L + 15% coconut milk. The highest frequency of callus induced was 11-15% and the mean frequency was over 3%.2. We find in this experiment that the medium Miller, MS and Nitsch can make anther callus of rice (O. sativa subsp. Shien) differentiate green plantlet.3. The ratio of kinetin and auxins has major effect upon callus differentiation of rice (Shien) anther. In our experimental condition it appears that the higher the ratio kinetin/auxin is, the higher the differentiation frequency both in the total, the plantlets and green plantlets. But abovementioned regular relationship is not very obviously observed in O. sativa subsp. Keng.4. The Miller's medium plus IAA 2mg/L is very suitable for root formation in plantlet without root. In this medium not only can root be induced but also it is very good for root development. The weak plantlets become fresher because the root has been well developed after it has been inoculated in this medium. If the plantlets have been transferred in this medium and directly planted into the pots afterward, the plantlets may be viable.

对6个籼稻(oryza sativa Subsp.Shien)品种和39个籼×籼杂种的花药在离体条件下进行培养,有5个品种及35个杂种得到了愈伤组织,平均诱导率为2.18%。在3个品种及11个籼×籼杂种中得到了绿苗或绿芽。本文着重报道基本培养基及其附加成分在诱导籼稻花药产生愈伤组织及根芽分化中的作用。 1.试验了几种诱导愈伤组织的培养基,以Miller培养基+2,4—D2毫克/升+酵母浸出液1,000毫克/升+激动素1毫克/升+吲哚乙酸2毫克/升+椰乳15%为最好。诱导率高者可达11—15%,平均诱导率在3%以上。 2.Ms、Nitsch及Miller培养基均可诱导籼稻花药愈伤组织分化出绿色的花粉植株。 3.籼稻花药愈伤组织的分化,随着激动素/生长素比值的增高,绿苗分化率及总分化率均有提高的趋势。而粳稻的这种关系不甚明显。 4.Miller培养基附加2毫克/升的吲哚乙酸对促进具茎、叶而无根的籼稻花粉小植株产生根有很好的作用。在这种培养基上,不仅可以诱导根的发生,而且根系发达,生长较弱的苗转移到这种培养基后,因根系健壮,生势好,转入盆栽,基本可以全部成活。

对已退化的育成晚籼品种平朝九号花粉植株二代群体及对照的比较试验发现,花粉二代植株在所研究的各种性状上均表现整齐一致,其标准偏差(S)及变异系数(C.V.)均比对照小,而各种性状均表现比对照优越。得出对已退化的育成品种进行花药培养可以起到提纯选优的作用。花药培养可以作为农作物品种提纯选优的一种多快好省的新方法。

The ploidy of about thousand pollen plants of rice that were obtained from anther culture in vitro were studied and the homozygosity and the hereditary rule of a part of those plants derived from hybrid F1 were investigated.Sixty per cent of the studied pollen plants were diploids,and set seeds normally.And ninety per cent of pollen plants of those derived from hybrid F1 produced uniform offsprings without any segregation,i.e.the progenies of those pollen plants were genetically homozygous.Segregation...

The ploidy of about thousand pollen plants of rice that were obtained from anther culture in vitro were studied and the homozygosity and the hereditary rule of a part of those plants derived from hybrid F1 were investigated.Sixty per cent of the studied pollen plants were diploids,and set seeds normally.And ninety per cent of pollen plants of those derived from hybrid F1 produced uniform offsprings without any segregation,i.e.the progenies of those pollen plants were genetically homozygous.Segregation either on characters or fertility or on both of them occurred in progenies of the rest 10% of the studied pollen plants,but appeared rather simple and obviously distinct from those in F.The recombination and segregation for four characters in forty nine pollen plants obtained from hybrid F1 of the same cross were studied in comparison with F2 plants of the same cross combination.Both of them showed fundamentally similar results.The experimental results,denoted that the frequency of producing pollen plants for various micrnspores of hybrid F1 were identical.And no obvious competition among pollens with different genotypes were observed during culture.Two new varieties of keng rice were obtained by means of pollen haploid plant breeding and have been put into-seeds propagation and distribution for practical production.

对自1972年以来,通过花药培养所获得的近千株花粉植株的倍数性和部分来源于杂种F_1的花粉植株的纯合性及性状遗传规律进行了研究。结果观察到60%的花粉植株为能正常结实的二倍体。90%来自F_1的花粉植株的后代是整齐一致没有分离的,也即在遗传上是纯合的。其余10%来自F_1的花粉植株的后代或在性状上、或在能育性上、或同时在性状与能育性上发生分离。但性状分离一般都较简单,与F_2的分离有明显区别。对来源于同一杂交组合F_1的49个花粉植株的四个性状的重组与分离的规律,以同组合F_2植株为对照,进行了研究。结果两者表现基本相似。说明杂种F_1的各种小孢子发育为花粉植株的机率是相同的,没有发现在培养过程中不同基因型的花粉间有明显的竞争。 通过花粉单倍体育种已培育出二个粳稻新品种在生产上繁殖推广。
