Diversity expressed by wheat germplasm under temperate Srinagar (J and K) Conditions

Abstract

To know the expression of diversity, their extent and pattern, field evaluations of 119 indigenously collected wheat germplasm were conducted under temperate valley conditions at KD Research Farm of NBPGR, Regional Station Jammu and Kashmir, India, for two consecutive years. All together 14 traits were undertaken. To measure the diversity simple statistical tools like maximum, minimum and standard deviation were taken into account. Correlation study, principal component analysis and cluster analysis were performed. Excellent amount of diversity were expressed by the tested germplasms. Standard deviation showed highest variation in yield deciding factors, i.e., the biomass and gain yield. Correlation studies accord that no. of spikelets / spike had maximum influence with other traits of Kashmir Valley conditions. PCA bi-plot study showed less variation as compare to other traits. Cluster analysis suggested that plant height was significantly correlated with all the traits except no. of spikelets / spike. Excellent amount of diversity were expressed under temperate Kashmir valley conditions by the all the tested wheat germplasms various traits, which can be utilised as donor in the temperate wheat breeding program.
