摘要

本研究以苦瓜(Momordica dioica Roxb.) 31个基因型为材料,进行遗传变异、相关分析和通径分析。茎株数- 1的PCV估计值较高(21.47),大多数性状的GCV和PCV估计值适中,表明基因型之间存在充分的遗传变异。高遗传力估计和高遗传进阶对果株数−1和果实产量的影响证实了这些性状是受加性基因作用控制的。果实产量与开花期、茎数−1、果实重和果数−1呈显著正相关。结果株数−1、茎株数−1、首次开花天数、果实重、果实直径和子房直径的相关性较高,可能是由于它们对果实产量的直接影响。研究表明,选择对果实产量具有高正显著相关和高正直接影响的性状有助于提高产量。相似系数为0.33 ~ 0.94。两两比较中,基因型与其他基因型的相似度最高,为0.32 ~ 0.50,相似度最低。

Genetic variability, correlation and path analysis of fruit yield in spine gourd (Momordica dioica roxb.)
The present study was conducted on 31 genotypes of spine gourd (Momordica dioica Roxb.) to estimate genetic variability, correlation and path coefficient analysis. The high estimates of PCV for the number of stem plant−1 (21.47) and moderate GCV and PCV observed for most of the traits which indicated the presence of adequate genetic variation among the genotypes. High heritability estimates coupled with high genetic advance for the number of fruits plant−1 and fruit yield confirmed that these traits are under the control of additive gene action. Fruit yield showed significant positive association with days to first flowering, number of stems plant−1, fruit weight and number of fruits plant−1. The higher association of number of fruits plant−1, number of stem plant−1, days to first flowering, fruit weight, fruit diameter and ovary diameter may be attributed to their direct effect on fruit yield. The study showed that the selection of traits with high positive significant association and high positive direct effect on fruit yield can help in improving yield. The similarity coefficient ranged from 0.33 to 0.94. In pair-wise comparison, the maximum similarity was obtained between genotype with a similarity index of 0.32 to 0.50, whereas genotype showed least similarity with other genotypes.
