Molecular mapping of genomic regions and identification of possible candidate genes associated with gynoecious sex expression in bitter gourd.

ABSTRACT: Bitter gourd is an important vegetable crop grown throughout the tropics mainly because of its high nutritional value. Sex expression and identification of gynoecious trait in cucurbitaceous vegetable crops has facilitated the hybrid breeding programme in a great way to improve productivity. In bitter gourd, gynoecious sex expression is poorly reported and detailed molecular pathways involve yet to be studied. The present experiment was conducted to study the inheritance, identify the genomic regions associated with gynoecious sex expression and to reveal possible candidate genes through QTL-seq. Segregation for the gynoecious and monoecious sex forms in the F₂ progenies indicated single recessive gene controlling gynoecious sex expression in the genotype, PVGy-201. Gynoecious p
