Bulked segregant analysis (BSA) of a BC1 population derived from Congguang 41A//Miyang 23/Congguang 41B was used to map the nuclear fertility restorer gene for Honglian (HL) cytoplasmic male sterility. One hundred and fifty-nine microsatellite primer pairs were screened for polymorphisms between the parents and between two bulks representing fertile and sterile plants. One microsatellite marker RM258 produced polymorphic products. The nuclear fertility restorer gene for HL cytoplasmic male sterility was mapped on chromosome 10, 7.8cM from RM258. The restorer gene may be clustered on chromosome.

In this paper, a simple control algorithm for the dynamic voltage restorer (DVR) is proposed to mitigate the power quality problems in terminal voltage such as sag, swell, harmonics, unbalance etc. Two PI (proportional-integral) controllers are used each to regulate the dc bus voltage of DVR and the load terminal voltage respectively. The fundamental component of the terminal voltage is extracted using the synchronous reference frame theory. The control signal for the series connected DVR is obtained indirectly from the extracted reference load terminal voltage. The proposed DVR control strategy is validated through extensive simulation studies using MATLAB software with its Simulink and Sim-power system (SPS) block set tool boxes.

The tolerance of a restorer line R1056 of rice and its hybrid combinations to high temperature at flowering stage was evaluated by sowing them at three dif- ferent dates and transplanting them into a greenhouse equipped with heating system at flowering stage. Several important agronomic traits of these rice varieties or combinations were also measured. The results revealed that treated by high temper- ature （38 ℃） at flowering stage, the seed setting rate （70.4%）, percentage of dehis- cent anthers （75.5%）, and pollen number per floret （78） of R1056 were close to those of N22, which is tolerant to high temperature, and significantly higher than those of the rice varieties sensitive to high temperature. The seed setting rate, per- centage of dehiscent anthers, and pollen number per floret of the hybrid combina- tions generated from R1056 were smaller than those of R1056, but higher than those of the rice varieties sensitive to high temperature. R1056 had excellent agro- nomic traits, and good combining ability, and its hybrid combinations had low plant height, numerous panicles and high yield, suggesting that R1056 is not only an ex- cellent rice variety with tolerance to high temperature, but also an excellent restorer in three-line hybrid rice breeding.

The availability of stable cytoplasmic male sterile(CMS or A) lines coupled with a robust restoration system(R lines) is an essential prerequisite for efficient hybrid ***-enabled hybrid technology holds immense potential to enhance the long-stagnant productivity of pigeonpea. In the present investigation, cytoplasmic substitutions were made in the nuclear backgrounds of early-maturing pigeonpea varieties or lines. Three new CMS lines(ICPL 88039 A, Pusa 992 A, and DPP 3-2A) resulted from genetic crosses involving cytoplasmic donors from A2(GT 288A) and A4(ICPA 2089) categories. In addition to visual inspection of anthers, pollen-staining techniques and scanning electron microscopy(SEM)analysis were used to confirm pollen sterility. Further, given the relevance of the plant mitochondrial genome to CMS manifestation, 25 mitochondrion-specific DNA markers were assayed on these newly developed A lines and isogenic maintainer(B) lines. DNA polymorphism between Pusa 992 A and Pusa 992 B as revealed by the nad7a_del marker confirmed the successful combination of sterilizing cytoplasm(A4) and nonrestoring nuclear background(Pusa 992). Such cytoplasm-specific DNA markers are required for A2-CMS as well. Further, to assess restoration ability, potential restorers were crossed with these CMS lines, and as a consequence, promising A × R combinations exhibiting 100%pollen fertility could be identified. In parallel, we also analyzed the inheritance patterns underlying fertility restoration using ICPL 88039A-derived F2 and BC1F1populations,and established a monogenic dominant model to explain the phenomenon of A2-CMS restoration. In summary, we report the successful development of new CMS lines and describe their effective deployment in hybrid breeding of pigeonpea.
