中文摘要 | 本試驗使用13個二稜大麥品種(系)與35個六稜大麥品種(系)栽培於秀 水、大安兩個地區,調查十個性狀以估算各性狀之穩定性介量、遺傳率、表現型 及遺傳型相關係數,結果如下: 1.各性狀經變方分析結果顯示:各品種與栽培地區的交感效應均方皆達極顯著水 準。 2.各性狀之表現型相關不論二稜或六稜大麥在兩地區多未達顯著水準,即或達顯 著水準者,則一處為正,一處為負。但二稜大麥產量和株高、穗重、每穗粒數在 兩地區均有正遺傳型相關關係,而六稜大麥產量和穗重、千粒重、容重量間呈正 遺傳型相關。 3.遺傳率估算結果,以抽穗日數與株高有最高的遺傳率。 4.性狀穩定性介值計算結果,二稜大麥中以CI80-754具較高產量及高穩定性。六 稜大麥中以CB-15具高產及高穩定性,而CI80-790則具高產且達平均穩定性。 |
英文摘要 | Ten characters in 13 varieties (strains) of two-row barley and 35 varieties (strains) of six-row barley at Show-Sei and Da-Ahan were investigated for studying their stability parameters, heritability, and phenotypic/genotypic correlation coefficients among various characters. Results were summarized as follows: 1.From the analysis of variance for ten characters it was found that the interactions between varieties and cultural environment were highly significant. 2.Phenotypic correlation at two locations wasn't significant or had the contrast (positive and negative) significance. Grain yield was significantly positive correlated with plant height, spike weight and number of kernel per spike for two-row barley at two locations. The spike weight, 1000-kernel weight and test weight for six-row barely were also significantly positive related to grain yield. 3.High heritabilities (99.0, 94.7 for two-row barley and 96.5, 87.2 for six-row barley respectively) were obtained in characters of days to heading and plant height. 4.Through Finlay and Eberhart's stability analysis, it indicated that CI 80-754 of two- row barley, CB-15 and CI80-790 of six-row barley were more stable and had high yield. |
