How should watermelon varieties be selected for summer-autumn cultivation?

Watermelons grown in summer-autumn cultivation have a shorter growth period. In the early stage, temperatures are high and humidity is high, with small day-night temperature differences; in the later stage, low-temperature overcast and rainy weather is often encountered. Weather conditions are changeable, and the requirements for varieties are strict. For cultivation, it is advisable to choose early-maturing or mid-maturing varieties that are high-quality, high-yielding, tolerant of high temperature and high humidity, have good female flower differentiation, set fruit easily, have relatively tough rind, are tolerant of storage and transport, and have strong disease resistance.
