    摘要:

    本试验对鲜食糯玉米的10个主要农艺性状与小区鲜穗产量进行了相关和通径分析。结果表明:小区鲜穗产量与单穗重、穗长、穗粗、行粒数、轴粗、百粒重呈极显著正相关,相关系数分别为0.615、0.523、0.443、0.392、0.364和0.341;与株高呈显著正相关,相关系数为0.315。在诸多性状中,对小区鲜穗产量直接作用最大的性状是单穗重,效应为0.4518;其次是轴粗,效应为0.3681;其它性状依次是百粒重、穗粗、穗位高、穗长、株高、秃尖长、行粒数、穗行数。

    Abstract:

    Correlation and path analysis of fresh ear yield and 10 major quantitative characters of fresh-eaten glutinous maize were made.The results showed that the fresh ear yield were significantly positively correlated with the average weight of ear,ear length,ear diameter,the number of kernel per row,axis diameter and 100-grain weight,the correlation coefficient were 0.615,0.523,0.443,0.392, 0.364 and 0.341.The fresh ear yield was significantly positively correlated with plant height,the correlation coefficient was 0.315.Among those characters,the greatest contribution to fresh ear yield was the average weight of ear,the efficient was 0.4518.The second was axis diameter,the efficient was 0.3681.Other characters were 100-grain weight,ear diameter,ear height,ear length,plant height,rare ear length,the number of kernel per row,the number of row per ear.
