About this variety

RF-101 is a Rajasthan-bred fennel variety, released in 2002, described as tall and erect with stout stems and long, bold grain. It matures in 145 to 160 days тАФ the shortest duration among the commonly grown named varieties, which matters directly for a crop that already spends five to eight months in the field. Its standout trait is high resistance to Ramularia blight, fennel's major leaf disease, reported consistently in variety-screening trials, with a reported yield of about 6.5 q/acre (roughly 16 q/ha). For a Rajasthan grower on a field with a known blight history, RF-101 is one of the two strongest resistant options, alongside the newer AF-3.
