- 摘要:
- 应用四粒荚比率高的长叶品种黑农36与遗传背景不同的5个圆叶品系(种)配制5个组合。对亲本、F1代和F2代群体的每荚粒数进行了调查和统计分析,结果表明: 长叶品种以三、四粒荚为主,平均荚粒数为2. 94。圆叶品系以三、二粒荚为主,平均荚粒数2. 40- 2. 64。F1 代,一粒荚数多表现略超高亲值。二粒荚数近于中亲值,三粒荚数略高于中亲值,四粒荚数略高于低亲值。每荚粒数表现为数量性状的遗传特点。F2代各种类型荚的变异有差异,一粒荚变异系数为97%、二粒荚40% 、三粒荚31. 1% 、四粒荚124. 3% ,三、四粒荚均有超亲遗传分离。F2 代,四粒荚与一粒荚的分布高峰均在5%组。二粒荚的分布高峰在30-35%组,三粒荚的高峰在60- 65%。各种粒数荚的广义遗传力( hB2 ) ,一粒荚为24. 4%、二粒荚33. 1%、三粒荚26. 3% 、四粒荚52. 7%。其顺位四粒荚> 二粒荚> 三粒荚> 一粒荚。
- Abstract:
- Fiv e crosses were made by using Heino ng 36 wi th narrow leaf let and high ra te of 4- seed pod per plant as common parent to cro ss wi th broad leaf let a nd low seed numberper pod to study the inheri tance of seed number per pod. The resul t indicated that thepod of narrow leaflet v arieties w ere coo perated w ith 3- seed pod a nd 4- seed pod, w hilethe pod of broad leaf let lines w ith 3- seed and 2- seed pod. The mean seed number perpod w as 2. 94 seeds and 2. 4 to 2. 64 seeds in the narrow and broad leaf v arieties ( lines) ,respectiv ely. In F1 , 1- seed pod number wa s hig her sligh tly than high- pa rent v alue, 2- seed pod o nes w ere near mid- pa rent v alue ( MPV ) , 3- seed pod ones w ere hig herslight ly tha n MPV , 4- seed po d o nes w ere hig her slight ly than low - pa rent v alue. Thecha racters o f pods wi th v ario us seed number behaved quantita tive inheri tance, the co efficiento f v aria tio n o f 1- seed po d, 2- seed pod, 3- seed pod and 4- seed pod w as97% , 40% , 30. 1% and 124. 3% in F2 populatio ns, respectiv ely. In F2 peak f requencydi st ribution ( PFD) of 1- seed pod and 4- seed pod was in 5% g ro up. PFD of 2- seedpod w as in 30- 35% g roups, PFD o f 3- seed po d w as in 60- 65% g roups. The broadsenseheri tabi li ty was 24. 4% , 33. 1% , 26. 3% and 52. 7% fo r 1- seed, 2- seed, 3-seed and 4- seed po d, respectiv ely.
