Evaluating the Growth, Yield, and Resilience of F1, F2, and Open-Pollinated Squash Varieties: A Comparative Study

In our country, malnutrition poses a severe challenge due to the limited production of nutritious food. Developing disease and pest-resistant varieties such as squash is crucial to tackle this issue. A recent study conducted in Can-ayan, Malaybalay City, Bukidnon, from July to October 2019, explored the growth and yield performance of different squash varieties (OP, F1, F2). The research aimed to understand the variations in yield, horticultural and reproductive characteristics, inbreeding depression, and profitability of growing diverse squash genotypes. The results, obtained through a Randomized Complete Block Design with five treatments, highlighted significant differences in traits among the genotypes. Notably, inbreeding depression was observed in marketable fruit production and yield. The analysis revealed varying traits across genotypes, with Gracia hybrid emerging as the most profitable choice, showing positive returns on investment. This study sheds light on the importance of developing resilient crop varieties like squash to address malnutrition challenges effectively.
