چکیده

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 ratio. The results revealed that grain yield per plant to be positively and significantly associated with days to maturity, number of productive tillers per plant, plant height and kernel length indicating importance of these traits as selection criteria in yield improvement programmes.

Genetic worth and stability of selection indices in rice (Oryza sativa L.)

Improvement of one trait on its own will affect the performance of other traits because ofgenotypic correlations between traits. Index selection is one of the tools used by plant breedersto overcome this problem. The purpose of this paper is to evaluate selection indices developedfor improving grain yield in rice (Oryza sativa L.). Forty-nine rice genotypes were cultivated atTonekabon Rice Rese...

Estimation of genetic diversity in rice (Oryza sativa L.) genotypes using SSR markers under salinity stress . Fatemeh Gholizadeh1* and Saeed Navabpour2

In order to study the genetic diversity in rice (Oryza sativa L.), 29 genotypes consisting land races, pure and improved lines were evaluated using simple sequence repeat (SSR) markers. A total of 30 SSR primers were used to amplify some part of rice genome in germplasms, the PIC values ranged from 0.07 (RM 340) to 0.71 (RM 7426) with an average of 0.45. The results showed a total number of 106...

Improving Rice (Oryza sativa L.) Drought Tolerance by Suppressing a NF-YA Transcription Factor

The response to drought stress is a complicated process involving stress sensing, intracellular signaltransduction, and the execution of a cellular response. Transcription factors play important roles in the signaling pathways including abiotic stress. In the present study a rice NF-YA transcription factor gene was partially characterized following dehydration. Disrupting the gene via a T...

Seed dormancy and seedling vigour as influenced by planting time environment and date of harvest in rice (Oryza sativa L.)

Seed dormancy is a genetically inherited trait whose intensity is modified by the environment during seed development and maturation. In order to study the effect of harvest time on the seed quality and optimum time of sowing to obtain good quality seeds, freshly threshed seeds of ten diverse rice genotypes harvested from six environments were evaluated for seed dormancy and seedling vigour ind...
