Seedling roots enable plant establishment. Their small phenotypes are measured routinely. Adult root systems are relevant to yield and efficiency, but phenotyping is challenging. Root length exceeds the volume of most pots. Field studies measure partial adult root systems through coring or use seedling roots as adult surrogates. Here, we phenotyped 79 diverse lines of the small grass model Brac...

In order to harvest higher yield of wheat, selection of suitable sowing technologies are of great importance. The objective of the present study included evaluation of profitability of innovative sowing technologies for wheat cultivation with limited water application by partial budgeting. Different sowing technologies i.e. Bed planting, Conventional tillage and Zero tillage were evaluated with...

ABSTRACT: This study determined the effect of different defoliation frequencies in a long-cycle ryegrass cultivar on yield components and physiological sanitary quality seeds. Four were applied (without, one, two, three defoliations). The time between defoliations was 350 degree-days. At first, second, third time, plants 15 cm, 20 35 respectively, lowered to half their height. plant structure e...

We have isolated a new recessive dwarf mutant of rice (Oryza sativa L. cv Nipponbare). Under normal growth conditions, the mutant has very short leaf sheaths; has short, curled, and frizzled leaf blades; has few tillers; and is sterile. Longitudinal sections of the leaf sheaths revealed that the cell length along the longitudinal axis is reduced, which explains the short leaf sheaths. Transvers...

The microRNA miR393 has been shown to play a role in plant development and in the stress response by targeting mRNAs that code for the auxin receptors in Arabidopsis. In this study, we verified that two rice auxin receptor gene homologs (OsTIR1 and OsAFB2) could be targeted by OsmiR393 (Os for Oryza sativa). Two new phenotypes (increased tillers and early flowering) and two previously observed ...

The aim of this study was to analyze sugarcane (Saccharum officinarum) biometric and technological data, obtained at different timepoints, using path analysis. The experiment was conducted in União, PI, Brazil, and evaluated 12 sugarcane genotypes (RB036066, RB9438, RB935744, RB021764, RB021754, RB021534, RB966229, RB977540, RB863129, and RB987935, and the varieties RB92579 and RB867515 as cont...

The studies on the correlation of the traits and their relative direct and indirect effects on yield are important, as they are helpful to adopt suitable selection procedure for yield improvement in inter-racial breeding programmes. In the present study, 15 wide compatible genotypes (11 tropical japonicas and four indicas) were crossed with six non-wide compatible genotypes (three each of indic...
