摘要
研究在不同处理条件下的地麦品种“杂14”节间和穗部性状与产量的关系,其结果表明:(1)随着肥力水平的提高和生长剂的施用,产量极显著地增加(2)株高,穗长,每穗实粒数,杆径和茎秆第1,2,5,6节的节间长与产量有显著或极显著的相关,可作为地麦育种选择的指标(3)不同栽培条件下,节间和穗部性状与产量的相关关系不相同因此,育种选择时,宜在能保证充分显现其育种材料特性的栽培条件下进行。
The relations between the properties of internodes, ear and yields for the land wheat variety “Za 14”under different treatments were studied The results show that:(1)The yield is very significantly enhanced with the improvement of fertility and the use of growth hormone (2)The correlation is significant or very significant between plant height, ear length, sead-bearing numbers per ear, stalk diametre, internode lengths of NO 1,NO 2,NO 5 and NO 6 nodes and yields, which can be used as the index of breeding selection of land wheat (3) Under different cultivating conditions the correlations between the properties of internodes, ears and yields are varied Therefore, the selecting effect would be excellent when breeding selection is carried out under the cultivating conditions under which the characters and properties of breeding materials are be fully showed
