An experiment was carried out to study the genetic components for eight panicle characters in rice using an 8-parent half diallel cross excluding reciprocals during Transplant Aman season, 2003. The parental genotypes used in the study were BRRI dhan29, BR4828-54-4-l-4-9, BRR1 dhan28, 1R8, Amol3, 1R6561038-2-4-2-6-3, Minikit and ZhongYu7, which were chosen for their diversity in panicle charact...
Characterization of genetic variability in a population is pertinent as genetic diversity within population and within species determines the extent of improvement achieved through crop improvement 8 methods. One hundred ninety six F recombinant inbred lines (RILs) of tef, developed by single-seed descent method from a cross between two tef varieties DZ-01-196 and DZ-01-2356, were evaluated to ...
Selection indices provide useful information to breeders who usually base selection on means and ranks. Knowledge on selection criteria for improving tef grain yield is very limited. Accordingly, the objective of this study was to develop selection criteria for improving tef grain yield through indirect yield component selection via a selection index. Different trait combinations along with thr...
The present study was undertaken with the objective to determine the nature and magnitude of variability, degree of association between yield and it`s component characters and their direct, indirect effects on grain yield in rice (Oryza sativa L.). Thirty three genotypes were evaluated for identifying their efficiency with respect to 20 yield and quality traits. High heritability with high gene...
a study was conducted on genetics of some important agronomic traits (number of productive tillers per hill, plant height (cm), panicle length (cm), number of spikelets per panicle and 100-grain weight) in rice during 2012-13. two lines were crossed with five testers in line × tester fashion to produce 10 f1 hybrids. analysis of variance revealed significant differences among genotypes and cros...
Thirty advanced breeding lines of deep-water rice were evaluated during T. Aman season (rainfed ecosystem) with a view to finding out variability and genetic association for grain yield and its component characters. All the tested characters showed significant variation. The highest genetic variability was obtained in filled grains/panicle followed by plant height. Panicles/plant, filled grains...

Isabgol is a medicinal plant known for its high-quality dietary fiber. The genetics and inheritance of economic characters, such as number of panicles, panicle length, seed yield, and swelling factor, were measured by diallel analysis of F(1) progenies from seven parents. The additive component of genetic variance was significant for days to flowering, plant height, branches/plant, peduncle len...
Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...
