25 Feb Seed Production Technology of Cucurbits
लता या बेल वाली सब्जीयों (कुकरबिट) के बीज उत्पादन की तकनीक 1. Varietal Seed Production of cucrbits Requirement of seed production The basic requirement of seed production is availability of improved varieties/hybrids and their demand among the farmers. Preferably the variety should be released and notified for certified seed production, however, any kind/variety can be multiplied for Truthfully Labeled Seed (TFL). The status of available varieties are given in table 2 and table 3. Isolation requirements The cucurbits are cross pollinated in nature and honeybees are major pollinator, thus for pure seed production an isolation distance all around seed field is necessaryto separate it from fields of other varieties, fields of the same variety not confirming to varietal purity requirement. The isolation distance of 400 m for C.S. and 800 m for F.S. and at least 1000 m isolation is required for breeder seed production.It is important to mention that muskmelon, longmelon and snapemelon (phoot) can cross with each other. Similarly, species of genus Cucurbita have the risk of crossability among them. The cucumber can cross easily with its wild relative Cucumis hardwickee found in wild form in sub-mountanious regions of Himalayas. Choice of season and areas of seed production : Seed crop should be raised in such a seasons which remain dry at the time of...
