GENETIC DIVERSITY IN LOCAL BORO RICE (Oryza sativa L.) GENOTYPES OF BANGLADESH
Genetic diversity in 40 traditional boro rice genotypes was studied under irrigated condition through Mahalanobis D 2 statistic for grain yield and yield contributing characters. The genotypes were grouped into five clusters. The inter-cluster distances were higher than intra-cluster distances indicating wider genetic diversity among the clusters. The intra-cluster distances were lower in all t...
متن کاملDIVERSITY ANALYSIS IN BORO RICE ( Oryza sativa L . ) ACCESSIONS
An experiment was conducted with 36 accessions of traditional (local) Boro rice germplasm accessions of three different groups (20 accessions as Kaliboro, 12 as Jagliboro and 4 as Tepiboro) during Boro season 2004 at BRRI farm to identify the duplicates with the help of morph-agronomic characters. On the basis of D values, the 36 genotypes were grouped into six clusters with a range of intra (0...
متن کاملHierarchical additive effects on heterosis in rice (Oryza sativa L.)
Exploitation of heterosis in crops has contributed greatly to improvement in global food and energy production. In spite of the pervasive importance of heterosis, a complete understanding of its mechanisms has remained elusive. In this study, a small test-crossed rice population was constructed to investigate the formation mechanism of heterosis for 13 traits. The results of the relative mid-pa...
متن کاملcombining ability and heterosis in rice (oryza sativa l.) cultivars
quantitative valuations of observed heterosis for 11 traits of 15 f1 hybrids generated by half diallel crosses of six diverse rice cultivars (domsefid, hashemi and binam, three iranian local cultivars; dorfak, kadous and ir30, three improved cultivars), were made in this study. fifteen f1 hybrids and their parents were evaluated in a randomized complete block design with three replications at t...
متن کاملHeterosis under aerobic condition in hybrid Rice
An experiment was undertaken to identify heterotic rice hybrids for aerobic condition based on physiological and root characters associated with water stress tolerance in rice. Panicle harvest index, a substitute for spikelet fertility is used as a secondary trait in the selection of drought tolerant genotypes. Deep roots are required to explore the soil profile for effectively absorbing water ...
