Varietal Trial on Palmarosa
Field and laboratory investigations were undertaken at Nagarjun Medicinal Plants Garden from 1984 - 1987 with object to find out the suitable variety of palmarosa having high yield of foliage and oil. From the pooled analysis the variety IW - 3631 showed highest dry foliage yield (10271 KG / ha) which was significantly superior over all varieties i.e, IW 3632, IW-3630, IW RRL (B) - 65 and IW - ...
متن کاملXIII EUCARPIA Biometrics in Plant Breeding Section Meeting
Over the last dozen or so years, population geneticists have actively been developing tests for signatures of selection using molecular data. Th ese tests fall into two broad categories. Tests of very recent (or ongoing) selection typically rely on withinand between-population data on the level of molecular polymorphisms around loci of interest. Tests for historical (i.e., over evolutionary tim...
متن کاملRapid breeding and varietal replacement are critical to adaptation of cropping systems in the developing world to climate change
Plant breeding is a key mechanism for adaptation of cropping systems to climate change. Much discussion of breeding for climate change focuses on genes with large effects on heat and drought tolerance, but phenology and stress tolerance are highly polygenic. Adaptation will therefore mainly result from continually adjusting allele frequencies at many loci through rapid-cycle breeding that deliv...
