Abstract

The goal of the current study was to assess genetic variability in Momordica dioica for both qualitative and morphological features to create trait-specific lines. The correlation coefficients among twenty-three different traits of twenty-one Momordica dioica gynoecious accessions calculated and summarized by using the best linear unbiased predictor (BLUPs). The traits contribution to principal components for growth, yield and yield attributing characters positively contributed towards the PC-I were tender fruit weight (FWT), mature fruit weight (FWM), ripen fruit weight (FWR), fruit yield per plant (MFYP), fruit yield per hectare (MFPH), seeds per fruit (NSF), fruit length (FL), fruit diameter (FD), inter-nodal length (IL), fruit pedicel length (FPL), leaf width (LW), leaf length (LL) and vine length (VL). Three groups were identified; group III had the most genotypes (10), followed by cluster II (07), and cluster I (04). Group II and III had the greatest inter-cluster value (8.73811), proceeded by group III and group I (8.738105) which indicates a wider genetic base among the genotypes under study. For the twenty-three traits, different genetic traits were analyzed, including heritability (H), genetic advance (GA), genetic advance as a percentage of mean (GAM), and phenotypic coefficient of variability and genotypic coefficient of variability (PCV & GCV). High PCV and GCV were noted respectively for the VL (26.93 and 26.24), number of stems per plant (28.12 and 21.03), LL (23.60 and 23.48), LW (21.21 and 21.09), FPL (37.53 and 36.74), FL (22.06 and 21.75), FD (22.65 and 22.60), FWT (39.77 and 49.76), FWM (51.07 and 51.01), FWR (51.97 and 51.79), fruits per plant (51.97 and 51.79), NSF (22.99 and 21.06), 100 Seed weight (141.25 and 141.25), MFYP (54.14 and 53.94) and MFYH (54.13 and 53.93). High GA as per cent grand mean was observed for VL (73.59%), number stem per plant (23.76%), FL (22.01%), FD (23.40%), FWT (24.07%), NFP (99.70%), 100 Seed weight (25.55%), MFYP (21.14%), MFYH (28.55%) and ascorbic acid (115.58%). The study provided a comprehensive of genetic variability of Momordica dioica for morphological and qualitative traits to support the development of gynoecious lines with specific traits.

摘要

本研究的目的是评估苦瓜在定性和形态特征方面的遗传变异性，以培育具有特定性状的品系。利用最佳线性无偏预测器（BLUPs）计算并总结了21份苦瓜雌性系材料23个不同性状之间的相关系数。对生长、产量及产量构成性状的主成分有正向贡献的性状中，PC-I包括嫩果重（FWT）、成熟果重（FWM）、熟果重（FWR）、单株果实产量（MFYP）、每公顷果实产量（MFPH）、单果种子数（NSF）、果实长度（FL）、果实直径（FD）、节间长度（IL）、果梗长度（FPL）、叶宽（LW）、叶长（LL）和藤蔓长度（VL）。共鉴定出三组；第三组基因型最多（10个），其次是第二组（7个）和第一组（4个）。第二组和第三组的类间值最大（8.73811），其次是第三组和第一组（8.738105），这表明所研究的基因型具有较宽的遗传基础。针对这23个性状，分析了不同的遗传性状，包括遗传力（H）、遗传进展（GA）、遗传进展占均值的百分比（GAM）以及表型变异系数和基因型变异系数（PCV和GCV）。VL（26.93和26.24）、单株茎数（28.12和21.03）、LL（23.60和23.48）、LW（21.21和21.09）、FPL（37.53和36.
