中共의 CGMS(細胞質-遺傳子的雄性不稔)을 利用한 雜種品種을 開發하기 爲하여 1982, 1983 兩年間 雜種品種의 收量性을 檢討하는 한편 韓國品種을 中共의 CGMS母本에 交配하여 그 F₁의 稔性을 檢定하고 MS維持系統을 2~4回 backcross하여 CGMS系統을 育成하였다. 그 結果를 要約하면 다음과 같다. 1. 雜種의 收量은 多收性標準品種에 比하여 4.6~24.3% 增收되며 組合에 따라 年次에 따라 環境에 따라 變異가 甚하였다. 收量의 雜種强勢現象은 主로 穗當粒數와 千粒重의 雜種强勢로 表現되었으며 穗數와 稔實率은 雜種에서 減收의 方向으로 作用하였다. 2. 稔性回復親의 收量性으로 그 回復親과의 雜種의 收量性을 推測할 수 없었으며 이러한 組合別 特異性은 出穗日數에서도 認定할 수 있었다. 3. V20A, V41A, Z97A 3個의 CGMS系統을 써서 24個의 維持系統과 30個의 稔性回復系統을 檢定하였다. 4. 本 硏究에서 供試된 中共의 CGMS系統 V20A, V41A 및 Z97A는 同一品種이 共通으로 維持系統 또는 稔性回復系統으로 될 수 있었음에 비추어 보아 3가지 MS系統이 다같은 體系의 MS라고 判斷된다. 5. 6個의 찰벼系統과 7個의 메벼系統을 2~4回 backcross해서 CGMS系統을 育成하였다. This paper reports the results of the studies on (1) the scope of the yield heterosis of the hybrids facilitated by the Chinese Cytoplasmic-Genetic Male Sterility (CGMS), (2) the fertility responses of the Korean cultivars and breeding materials in the hybrids crossed with Chinese CGMS and (3) the progress of breeding CGMS lines utilized by the Chinese CGMS. The results are summarized as follows: 1. Though the variations were significant depending on the cross combinations, years and environments, the hybrids showed 4.6%-24.3% higher yield over the highest yielding check variety. Their yield heterosis were expressed through the increased number of grains per panicle and grain weight. 2. The yield and heading data of a hybrid were not able to directly estimate through its parents, implying the manifestation of specific combining ability. 3. Among the 86 cultivars and breeding lines tested for the grain fertility of their hybrids with the Chinese CGMS lines, V20A, V41A and Z97A, 24 of them showed nearly complete sterility and 30 of them showed nearly complete fertility. These will be utilized as a MS maintainer or as a fertility restorer. 4. Many cultivars and breeding lines tested here responded as a MS maintainer or as a fertility restorer common to all of three CGMS lines, implying that they belong to the same MS system. 5. Six of waxy and seven of non-waxy CGMS lines are being bred through the back-crosses 2-4 times to the Chinese CGMS lines.

短稈 Japonica 品種들의 Semi-dwarf (d-t) gene에 對한 allelism을 檢討하기 위하여 Semi dwarf gene을 가진 wx 817과 그에 대하여 allelic tall 因子를 가진 Binato를 檢定親으로 하여 Binato에 6個의 短稈 Japonica 品種을 交配하여 그 F₁, F₂ 및 F₃를 展開하여 稈長을 調査하였다. 그 結果를 要約하면 다음과 같다. 1. 檢定親稈 組合인 Binato×wx 817의 F₂에서는 長稈:短稈이 3:1로 分離되어 기왕의 報告와 一致하였다. 2. 供試된 短稈 Japonica 品種들은 檢定親인 Binato와의 組合 F₂에서 年次間 變異에 關係없이 모든 組合에서 長稈:短稈이 3:1로 分離되었다. 3. 短稈群에서 選拔된 F₃系統은 選拔 當時의 稈長을 中心으로 正規分布를 나타냈으나, 長稈群에서 選拔된 系統은 分離하는 것과 그렇지 않은 것이 2:1로 分離되어 理論値에 適合하였다. 4. 組合에 따라서는 F₃系統의 稈長 變異의 幅이 F₂集團에 비하여 다소 短稈된 組合과 伸張된 組合이 있었으나 稈長의 分離 樣相은 모든 組合에서 同一하였다. 5. 以上의 結果로 보아 供試된 短稈 Japonica 品種들의 稈長을 支配하는 主??遺傳子는 同一하지만 組合에 따라 서로 다른 微??遺傳子가 存在하는 것으로 推定된다. 6.F₂長桿群에서 選拔한 2群, 長一長群과 長一短群은 F₃에서 분명히 差가 나는 mode를 나타내어 選拔의 를 할 수 있었다. F₂短桿群에서 選拔한 F₃個體들의 變異를 보아 短稈群에서의 選拔도 有意할 것으로 추축되었다. Investigations were made to search for the semi-dwarf Japonicas allelic to the semi-dwarf rice cultivars which is controlled by d-t gene. Six dwarf Japonicas, Reimei,Hoyoku,Shiranui,Kokumasari, M.7 and S.224 were crossed to the tall tester cultivar, Binato. Binato is known having tall allelic gene to semi-dwarf gene d-t. Their F₁, F₂, and F₃ were grown in 1984 and 1985 and culm length were measured at harvest. The results are summarized as follows: 1. In the F₂ of test cross, Binato/wx817, culm ength was segregated 3 tall to 1 short, which conformed the tester's validity. 2. The F₂s of all 6 crosses showed 3 tall to 1 short segregation which indicated the short Japonicas were allelic to the tall tester variety. 3. F₃lines selected from short group of F₂showed no segregation but F₃ lines selected from tall group of F₂ were segregated in to 2 segregating and 1 not-segregating. 4. The range of variation of the short segregants and the tall segregants were variable depending on the cross combination, but the general patterns were similar in all 6 crosses. 5. From the results of F₂and F₃ segregations, it was concluded that the 6 semi-dwarf Japonicas tested here were controlled by same major gene d-t though they were modified by different minor genes. 6. The modes of segregation in F₃s selected from taller tall and selected from shorter tall were significantly different in every crosses which implies the selection effects. The selection effects in the short group also was presumed from their wide variations in F₃.

Alkali digestibility value (ADV) were tested for the F₁ and F₂ seeds of the crosses among low, medium and high ADV parents. Hybrid seeds of seven possible different combinations among low, medium and high ADV parents, i.e. LLL, LLM, MML, MMM, MMH, HHM, and HHH, were obtained at high and low temperature utilizing cytoplasmic male sterility to minimize the influences of hybridization operations. ADV of seven different hybrids LLL, LLM, MML, MMM, MMH, HHM, and HHH were 1.25, 1.63, 1.80, 3.43, 4.68, 4.95, and 5.67 at high temperature and 1.82, 4.00, 4.19, 6.38, 6.38 6.38 and 6.50 at low temperature respectively. ADV of F₂ seeds turned out 3 low to 1 medium in the cross of low and medium ADV parents while no theoretical value observed in the cross of medium and high ADV parents at both temperature conditions. From the results it was concluded that the ADV is controlled by one major gene, low ADV being dominant over medium ADV, and a few minor genes which modifying the ADV of different medium 1 low dosages of endosperm, while the dosage effect of high ADV to medium ADV appeared to be additive at high temperature only. All the combinations showed significantly high ADV value at the low temperature, and the temperature effects were higher in the M-ADV combinations.

The resistance to the bacterial leaf blight derived from cultivar IR2061-214-2 in rice was controlled by a single dominant gene, and it was located in linkage group II of Nagao and Takahashi. It was independent from the semi-dwarf plant type and resistance to brown plant hopper and smaller brown plant hopper which are not identified their linkage relations yet. To assure the inheritance of the resistance to the bacterial leaf blight(Xanthomonas oryzae) derived from cultivar IR2061-214-2 and 7 linkage tester lines. The cultivar IR2061-214-2 is a semi-dwarf line resistant to brown plant hopper (Nilaparvata lugens) and smaller brown plant hopper(Laodelphax striatellus). Their F₁s and F₂s were grown along thir parents, and the segregation of the characters were studied. The results are summarized as follows: 1. The resistance to the bacterial leaf blight derived from cvltivar IR2061-214-2 inherits as coutrolled by a single dominant gene. 2. The resistance (Xa) showed linkage with the characters such as phenol staining (Ph), liguless (lg) and the complementary gene of purple pericarp (Pb) with the recombination values of 6.1%, 8.1% and 34.3% respectively. The serial loci are estimated as in the order of Pb-lg-Ph-Xa. 3. The resistance to the bacterial leaf blight was independent from the semi-dwarf plant type. 4. The resistance to the bacterial leaf blight was also independent from the resistance to the brown plant hopper and smaller brown plant hopper.

M. H. HEU(許文會),H. S. SUH(徐學洙) 한국육종학회 1976 한국육종학회지 Vol.8 No.3

A poly-caryopsis was found in one family among the 19 families of the BC₁F₂ of the rice cross between Japonica cultivar Suwon 224 and Javanica cultivar Malagkit Sinaguing. All of the plants derived from the poly-caryoptic plant showed poly-caryopsis. The ratio of poly-caryopsis in the poly-caryoptic plant varied from 71.5 to 85.7%. The single caryopsis was found more on top than on basal part of rachilla in a panicle of the poly-caryoptic plant. The poly-caryopsis derived from wx154-134-40 inherits as single recessive character and it is linked with long empty glume (g) belonging to the linkage group IV, where the recombination value calculated was 30.0±5.2%. The gene symbol pc was suggested for the poly-caryopsis derived from wx154-134-40.
