Since 1996, the Rice Research Institute of Liaoning Province has laid stress on the genetic improvement of stigma exsertion rate of japonica male sterile lines. By introducing the genes of high stigma exsertion rate from indica into japonica, a group of japonica male sterile lines with high stigma exsertion rate have been successfully developed. Their stigma exsertion rate have been greatly increased from less than 30% to more than 80%, resulting in an increased outcrossing rate over 60% and a high seed production yield of 3.0~4.5 t/hm^2. Moreover, using these sterile lines, a group of new japonica hybrid rice combinations such as Liaoyou 5218 (Liao 5216A/C418), Liaoyou 1052 (Liao 105A/C52) have been developed and released to commercial production.

Compared with 810S,the total photosynthetic pigment content of Biao 810S was aabout 50%lower;which was the main cause of the yellow green leaf.2、The spikelet numbers,stigma exsertion rate and flowering time of Biao 810S were same as that of 810S.There were no significant difference of the agronomic traits between the the cross combination which came from the maintainers D100 and R96-1 and the combination from 810S.3、The photosynthetic rate of Biao810S was higher than 810S under strong light and lower under weak light.
叶绿素含量下降是标810S叶片呈淡黄绿叶色的根本原因。2、标810S的颖花数、柱头外露率和开花时间与对照基本相当，与恢复系D100和R96-1配制的杂交组合农艺性状与用810S配制的相应推广组合无明显差异，表明标810S可替代810S应用于两系杂交水稻，其淡黄绿叶色性状可应用于杂交制种田的不育系群体除杂，同时可根据幼苗期淡黄绿叶色性状植株的比例用于鉴定杂交组合中不育系的混杂率。3、弱光条件下标810S的光合速率低于810S，强光条件下标810S光合速率比对照高，且标810S在光强2400μmol·m~(-2)·s~(-1)以下没有光饱和点和"午休"现象。

The study suggest:(1) The observation of satellites in root tip and multiplex PCR makers could accurately identify the homozygous and the heterozygosis of 1BL/1RS translocation.(2) Through the restoring degree we could confirm the success of the transfer. The combination of the restoring degree and the agronomy property could increase the efficiency of practical application.(3) This study proposed the transformation from the physiological male sterile to the genetic male sterile, and then establish a method of utilize the strong superiority crosses.
其中复合引物PCR更适合于回交后代中大量目标种子的筛选；(2)恢复基因转育后代定株与不育系测交，依据测交恢复度可准确确定恢复基因在回交后代的延续，恢复基因定株定向转育与性状选择结合可大大提高转育后代的实际应用效果；(3)本研究提出的粘类小麦雄性不育恢复基因Rfv1定向转育体系，可有效地实现小麦由化控强优势组合向三系强优势组合的定向转化，即生理型不育途径向遗传型不育途径的定向转化，进而建拓一套杂交小麦强优势组合多途径利用新体系。

These male sterile transgenic plants with TA29 Barnase gene have the same horticultural characters which can be also inherited steadily by plants in next generation as non transgenic ones. But their flowers bear fully catagenetic stamen lacking pollens, normal fragrant nectaries and strong pistils able to receive pollens from other plants or different cultivars and set seeds. At the meantime, the sterility i...

The sterile and fertile plants of BC3 generation, derived from the hybridization between sterile line and restorer line and maintaining line, were detected by GISH-dcFISH. The observations showed that the fertile plants were all the Brassica napus-Xinjiang wild Sinapis arvensis monosomic alien addition lines, and the sterile plants had no Sinapis arvensis chromosome.

In this paper, male sterile line of alfalfa was used to be improved with crossing, because the seed production of crossing is low. The affecting factors of seed production of male sterile line of alfalfa and its crossing progenies that are crossed with male sterile lines of alfalfa and good alfalfa that male is fertile were analyzed. The characteristics of female reproductive organs of male sterile line and its crossing progenies are analyzed in cell morphology. The genetic difference of male sterile line and its crossing progenies are analyzed in enzyme protein. The results showed: 1、Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plant BC1-2 that is the crossing progency of male sterile line of alfalfa and Medicago varia Martin.cv.'Caoyuan No.1'is higher than male sterile lines. Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plants BC1-19、BC1-21、BC1-22、BC1-23 that are the crossing progencies of male sterile line of alfalfa and Medicago sativa L.cv.
