DIVERSITY AND ABILITY TO GROW AND DEVELOP OF INTEGRATED VARIETIES

Abstract

The objective of this study to analyze the genetic diversity, growth and developmentof 30 muskmelon (Cucumis melo L.) inbred lines belonging to Cantaloupensis group (lines numbered from D1 to D22) and Reticulatus group (lines numbered from D23 to D30). The inbred lines were developed by selfing exotic germplasms introduced from China, Japan and Israel at the Crop Research and Development Institute (CRDI). The inbred lines were grown in nethouse conditions in Spring and Autumn-Winter season 2019. The results showed that, most inbred lines were able to grow well under nethouse conditions in Gia Lam, Hanoi. Those lines have short growth duration, good agronomic characteristics, resistance to pests and diseases, high fruit and seed yield. High genetic variability was observed based onvarious morphological characters of melon inbred lines. Five elite varieties were identified included D13, D17, D20, D24, D27. These are important materials that are used in subsequent breeding programs for conservation and maintenance. The information of phenotype-based diversity of this studycan be utilized for high yield and quality melon breeding program.
