Abstract
(Gossypium hirsutum L.)" involved the study on growth and
development characters, phonological development, biochemical character,
yield and yield contributing characters. The material used were seven Bt
cotton hybrids and its non Bt version of each Bt hybrid which was Rudra ,
Sigma , Tulsi, Akka, Dyana, PRCH-31 and Bunny etc .. A wide ofvariation
was found for almost all the characters.
There were significant differences observed among Bt and its
non Bt genotypes. Among all other Bt hybrids Rudra Bt showed better
performance for all growth and development characters . Observations on
yield components show that number of bolls per plant, boll weight and yield
per plant were most important to decide seed cotton yield. The hybrids
(Rudra) Bt-l and (Rudra) NBt-1 were superior in these character, among Bt
and non Bt hybrids respectively. Therefore yield performance was better in
these genotypes ..
