Even though changes in transcription patterns, which correlated with male sterility, were detected for three of the probes (atpA, orf25 and coxII), the changes were not consistent for all the male-sterile materials.
      
The sterile materials were not fully separated from soiled materials, thus introducing a contamination hazard.

In 1973,in the field of the single cropping late Geng-type rice (O.sativa subep.japonica) cv.Nongken 58,the author found one spontaneous male-sterile plant.The tillers of this material heading before Sept.3 were sterile,but fertile after Sept.8.Results obtained from many years experiments are as follows:(1) The F1 of the male-sterile plant when crossed with any Geng-type rice produces fertile plants under long-day or short-day conditions.(2) The F1 of reciprocal crosses produces no sterile...

In 1973,in the field of the single cropping late Geng-type rice (O.sativa subep.japonica) cv.Nongken 58,the author found one spontaneous male-sterile plant.The tillers of this material heading before Sept.3 were sterile,but fertile after Sept.8.Results obtained from many years experiments are as follows:(1) The F1 of the male-sterile plant when crossed with any Geng-type rice produces fertile plants under long-day or short-day conditions.(2) The F1 of reciprocal crosses produces no sterile plant under long-day or short-day conditions.(3) The Geng-type sterile plant when crossed with Geng-type hybrid F1 produces both sterile and fertile plants in a ratio of 1:1 under a long-day condition.(4) The F?Geng-rice hybrids,whether from crosses or reciprocal crosses,are segregated into about 1/4 sterile plants and 3/4 fertile plants Tinder a long-day condition.In 1984,Deng Jingyang made analysis of the data obtained and took this pheno-to be controlled by a pair of photosensitive recessive male-sterile key-genes not hitherto reported,which is given the name Hubei photosensitive genie male-sterile rice.Photosensitive male-sterile rice is a typical example of physiological genetics,and can be used for multiple breeding in the following aspect:(1) It can be utilized to create heterosis.The sterile material can reproduce itself by selfing under short-day condition,and the crosses can be made under long-day condition to produce hybrids.The male parents can be obtained by extensive screening (including the use of newly-bred varieties and strains).It is simpler and more economical than the present three-line-hybrid-rice of nucleo-cytoplasmic interaction;(2) Following the utilization of Fi heterosis,superior fertile plants from the offsprings can be selected to obtain new varieties;(3) It also can be employed in the composite crossing and recurrent selection for the accumulation of useful genes to improve populations so that outstanding varieties can be bred;(4) It is a more convenient and efficient in making crosses between Xian-type rice (Subsp.indica) and Geng-type rice.

1973年在湖北发现了一株不育水稻,它在长日照条件下不育,在短日照下则可育。经鉴定,它的不育性是受一对对光照长度敏感的隐性雄性不育主基因控制,是在植物界首次被发现,是生理遗传的典型例子;用于理论研究有很大的科学价值,作为杂种优势利用,可以在短日照下自交繁殖,在长日照下杂交制种,一般粳稻品种都可以作为父本使用,杂种一代在任何生长季节下都能发挥其增产作用。这株水稻被命名为“湖北光感核不育水稻”,这个对光照长度敏感的隐性雄性不育基因被命名为msh。

It has beer proved in the practice of cotton production in Sichuan that the utilization of intervarietal heterosis in upland cotton is a successful way to breed the hybrids with high yield,disease resistance and good quality.The hybrids Chuanza 3, Chuanza 4 and Zajiaozhao have been spreaded in cotton production in Sichuan and their competitive heterosis were as high as 15.1-33.6%. The lint yield increased by hybrids averaged 138.6-177kg/ha. Up to today, 4 dominant male sterile materials and 3 recessive male sterile genes have been found from upland cotton.Dong A,Shi A and Lang A are the representative materials for the three recessive genes respectively. The gene marks were tentatively named msc1, msc2 and msc3 in order. Using msc1 and msc2, three nuclear male sterile lines-473A, kangA and 1355A-which have the merits of high yield, disease resistance and high fibre strength have been selected and they have been used as both A and B line in the seed production of hybrid cotton. For the present nuclear male sterile lines, a complete maintaining line-Mline-has been selected from a material in which there probably are modifying genes or gene interaction. It could make the frequencies of both sterile plant and sterile flower of the subsequent generations of cotton plant with a pair of msc1 genes maintain 100%. It may open up a new way for the utilization of heterosis of cotton in the future. The techniques and system of seed production of hybrid cotton by the method using the nuclear male sterile line as both A and B line also are discussed in this paper.

四川的棉花生产实践已证明:陆地棉品种间的杂种优势利用是一条实现丰产、抗病、优质的育种途径。已推广的“川杂3号”、“川杂4号”和“杂交早”等杂交种其竞争优势达15.1~33.6%,平均皮棉产量增加9.24~11.8公斤/亩。迄今,我们在陆地棉中已发现4个显性雄性不育材料和三个隐性雄性不育基因。携带有这三个隐性雄性不育基因的材料分别以“洞A”、“石A”和“阆A”为代表,其基因符号依次暂定为msc_1、msc_2和msc_3。利用msc_1和msc_2基因已分别育成丰产、抗病和高纤维强力的3个核雄性不育两用系“473A”、“抗A_1”和“1355A”用于杂交种的配制。已从一种可能具有修饰基因或基因互作的材料中育成了对现有棉花核雄性不育系的完全保持系——M系,可使msc_1基因纯合棉株的后代不育株率和不育度都达到100%。有可能为今后棉花杂种优势利用开辟一条新途径。本文还论述了“两系法”的制种技术和杂交棉种子生产体系。

The male sterile-maintainable lilies of blue grained wheat has been preliminarily selected by marking the nucleus male sterile materials with blue pigment gene of seed endosperm of blue grained wheat. It has resolved the difficulty of the nucleus male sterility to be maintained, and has realized complete system of "three lines". It opens a new way to research and apply male sterility in production of hybrid wheat.
