稉稻產量構成要素及農藝性狀對產量穩定性之影響 Taiwan Agricultural Research Institute
呂秀英; 呂椿棠; 陳正昌; H. Y. Lu; C. T. Lu; C. C. Chen.
[[abstract]]本研究之目的在利用1990至1991年間11個稉稻品系於7個地區進行兩年各二期作的區域試驗資料為分析材料,闡明稉稻產量構成要素及農藝性狀對產量穩定性的影響,並探討利用其他性狀進行間接選拔以提高稻穀產量穩定性的可行性。結果得知: 1. 不同期作下不同性狀配合直線迴歸模式的效率有相當之差異,各性狀之廣義遺傳率愈高,適用性也愈好。 2. 由於第一期作產量的平均值與穩定性係數間之正相關關係不存在,因此可從中選育出高產且穩定的品系,如臺稉育34號、4268號、4160號及4156號等四品系;第二期作之產量,各新育成品系似乎並無突出優秀之表現,且產量愈高者其穩定性也較差。 3. 對產量穩定性有影響的性狀在第一期作為千粒重,第二期作則為全生育日數;亦即千粒重較小或早熟品系的產量對環境之變化較為穩定。但由於此等性狀對產量穩定性的影響結果似乎與遺傳機制無關,故將之應用於產量穩定性的間接選拔上,仍相當困難。 Experimental data from the 1991-1992 regional trials of japonica rice were used to determine the effects of yield components and some agronomic traits on yield stability. The possibility of indirect selection of these traits for enhancing yield stability was also examined. The results were summarized as follows. The effectiveness of regression...

水稻期作與地區間產量及產量構成要素之品種間差異 Taiwan Agricultural Research Institute
蔡金川; J.C. Tsai.
[[abstract]]本試驗以秈稉稻各十五個品種為材料,分別於臺北及臺中地區進行兩期作之田間試驗,調查各品種之抽穗期,並於成熟期測定產量與產量構成要素。目的在探討水稻品種於不同期作或地區間,對於產量及產量構成要素之表現狀況,及其品種間之差異,所得試驗資料,可供育種家之參考應用。 由試驗結果得知,秈稉型品種第一期作之產量高於第二期作,臺中大於臺北地區。產量及產量構成要素之期作間或地區間之差異,及品種間差異皆達1%水準的顯著性差異。其他之交感作用大部分亦極顯著。而產量構成要素方面除了千粒重之外,其餘與產量之變異並不一致。 不論期作或地區,表現高產品種為臺農67號(Tainung 67)、臺南5號(Tainan 5)、臺東29號(Taitung 29)、臺中秈10號(Taichung Sen 10)及嘉農秈11號(Chianung SEN 11),而期作性豐收之品種,第一及第二期作分別為臺農62號(Tainung 62)、高雄秈7號(Kaohsiung Sen 7)與豐錦(Toyonishiki)、臺農秈12號(Tainung Sen 12)這些品種大部分屬於穗數型。穗數之環境(期作、地區)間之品種相關係數皆為正相關,表示穗數對不同環境有較穩定性之表現。 Fifteen each of Japonica and Indica rice cultivars were grown under natural conditions in both the 1st and 2nd crop seasons at Taipei and Taichung.

Combining ability analysis for yield and yield components in bold grained rice (Oryza sativa L.) of Assam Acta Agron. (Palmira)
Chakraborty,R; Chakraborty,Supriyo; Dutta,B.K.; Paul,S.B..
Combining ability analysis for grain yield and its components was carried out in eight parental diallel crosses of bold grained rice excluding reciprocals. The general combining ability (GCA) and specific combining ability (SCA) effects were significant for all the characters indicating the importance of both additive and non-additive gene effects in their inheritance. The parents Ranjit followed by Matonga and Monohar Sali contributed significantly to high GCA effect towards high grain yield per hill. The superior specific cross combinations for high grain yield per hill were Matonga/Bar Madhava, originated from high x low GCA combination followed by Dhola Mula/ Ranjit (low x high gca), Chandmoni/Hathi Sali (low x high GCA), Dhola Mula/Mala (low x low...

Genotype by environment interaction for seed yield per plant in rapeseed using AMMI model PAB
Marjanović-Jeromela,Ana; Nagl,Nevena; Gvozdanović-Varga,Jelica; Hristov,Nikola; Kondić-Špika,Ankica; Marinković,Mirjana Vasićand Radovan.
The objective of this study was to assess genotype by environment interaction for seed yield per plant in rapeseed cultivars grown in Northern Serbia by the AMMI (additive main effects and multiplicative interaction) model. The study comprised 19 rapeseed genotypes, analyzed in seven years through field trials arranged in a randomized complete block design, with three replicates. Seed yield per plant of the tested cultivars varied from 1.82 to 19.47 g throughout the seven seasons, with an average of 7.41 g. In the variance analysis, 72.49% of the total yield variation was explained by environment, 7.71% by differences between genotypes, and 19.09% by genotype by environment interaction. On the biplot, cultivars with high yield genetic potential had...

การใช้ปอเทืองเป็นปุ๋ยพืชสดที่มีต่อผลผลิต องค์ประกอบผลผลิต และปริมาณไนโตรเจนของข้าวสังข์หยดพัทลุง Thai Agricultural
Somporn Kamyot.
The research objectives were to investigate green manure species namely Crotalaria juncia on yield, yield components and nitrogen content of rice cv. Sangyodphatthalung was conducted in paddy soil condition of Phatthalung Soil Series. The experimental design was RCBD of which consisted of 7 treatments by using different seed rates (kg rai-1) as compared to chemical fertilizer i.e. 0, 5, 10, 15, 20, 25 and 8-10-0 kg N-P2O5-K2O rai-1. The results of yield showed that significantly different with different seed rates, the treatment of 15, 20, 25 kg rai-1 and CF gave similar highest average yield (386.8, 388.9, 385.7, 409.5 kg rai-1 respectively) and highest average number of no. of panicle hill-1, no. of spikelet panicle-1 and % of filled grain whereas the N...
