‘平陆尖枣’实生后代主要性状变异分析与评价
|
摘要
以‘平陆尖枣’的19个实生后代为试材,对其主要枝干性状、叶片性状、针刺性状及果实性状进行了观测。结果表明:变异系数最大的3个性状为二次枝节数、单果重、可滴定酸含量;变异系数最小的2个性状为叶片宽、中心干针刺长度。实生后代中,大于50%的后代在枣头颜色、叶缘、叶片形状表现相同或相似。对单果重、果实纵径、果实横径、叶面积4个性状进行了相关性分析,发现单果重与果实纵径、果实横径均呈显著正相关;且果实纵径与果实横径呈显著正相关;叶面积与果实纵径、果实横径呈显著正相关。另外筛选出富含可溶性总糖的种质7个、富含可滴定酸的种质2个。
In this experiment, 19 main progeny of 'Pinglujianzao' were used as materials to observe the main branch traits, leaf traits,acupuncture traits and fruit traits. The results showed that the variation coefficient of the three traits, such as the number of secondary branches, single fruit weight and titratable acid content, was the largest; the variation coefficient of leaf width and central stem needle length was the smallest. More than 50% of the offspring showed the same or similar performance in the color, leaf margin and leaf shape of the jujube. Correlation analysis of the single fruit weight, fruit longitudinal diameter, fruit transverse diameter and leaf area showed that the single fruit weight was significantly positively correlated with the longitudinal diameter of the fruit and the transverse diameter of the fruit; And the fruit vertical diameter was significantly positively correlated with o the fruit transverse diameter. The leaf area was significantly positively correlated with fruit longitudinal diameter and fruit transverse diameter. In addition, 7 high-sugar germplasms and 2 acid-rich germplasms were screened.
