Abstract

A comprehensive study on Phule Shubhra (RHB-1623), a novel hybrid cotton designed for extra-long staple length (ELS) cotton production, combining the genetic lineage of Gossypium hirsutum L. and Gossypium barbadense L. Through meticulous genetic characterization and agronomic evaluation, Phule Shubhra emerges as a standout choice for cotton cultivation, boasting high yield potential, superior fibre quality, and enhanced tolerance to sucking pests and bollworms.Notably, Phule Shubhra demonstrates consistent performance in higher seed cotton yield, boll weight and bolls per plant, coupled with ELS, favorable micronaire values, and robust bundle strength, positioning it as a top contender in fibre quality.Additionally, the hybrid exhibits commendable resistance to major diseases such as Alterneria Leaf Spot, Bacterial Leaf Blight, and Grey Mildew, along with varying levels of tolerance to insect pests.Detailed morphological characterization and DNA fingerprinting analysis, including SSR markers, further elucidate Phule Shubhra's distinctiveness and genetic inheritance, offering valuable insights for breeding and selection programs.In summary, Phule Shubhra represents a breakthrough in cotton agriculture, promising sustainable and profitable cultivation practices for growers in the Central zone.
