Once a mother plant releases its embryos to the outside world, they have to survive on their own without family protection. To ensure successful colonization by these vulnerable creatures, the mother ...
An advanced line with code number V-04189 was selected at Wheat Research Institute, AARI, Faisalabad in 2003-04 from bread wheat breeding material of CIMMYT on the basis of its attractive plant type, ...
The crop management in direct-seeded rice to promote growth during the reproductive stage was evaluated in weed-controlled toposequentially intermediate fields in a small watershed in Northeast Thaila...
Twenty eight genotypes in M4 generation evolved through use of gamma radiation were evaluated at Nuclear Institute for Agriculture and Biology, Faisalabad, Pakistan during 2005-06. Layout system was...
Three high-yielding japonica-indica hybrid (JIH) and semidwarf indica (SDI) rice varieties, and ten japonica (J) rice varieties, including different plant types, were cultivated under sparse (30×30 cm...
In order to clarify the characteristics of high yielding rice varieties, total dry matter production, yield and harvest index were compared in 1988 and 1989 among the two early and three medium variet...
The difference of dry matter production process among the rice cultivars was previously reported with reference to light intercepting characteristics. This study was conducted to determine if the sing...
Canopy photosynthesis was simulated by using the modified Horie's model (1981) on the basis of measured canopy structure (Fig. 1), light intercepting characteristics (Fig. 2, 3, 4, Table 1) and leaf p...
Analytical study on the high yielding characteristics of the rice varieties with reference to matter production and photosynthesis.
In order to investigate the breeding objective on the improvement of rice yield, the yield structures were analyzed and compared among a hundred varieties. By using the mean specific gravity (S), all ...
To compare the growth, yielding ability and water consumption in the two cultivated rice specks, Oryza sativa L. and O. glaberrima Steud., the respective six strains of O. sativa and O. glaberrima col...
9004 (L9), which is a high yielding japonica type glutinous rice line developed in Jiangsu province, China, was cultivated under different combinations of nitrogen (N) application with or without pho...
The critical developmental stage, during which the genotypic difference in yield is determined, was identified by analyzing the correlations between seed yield and seasonal crop dry matter productivi...
A field experiment was carried out to investigate the dry matter production characteristics before and after heading, the partitioning of dry matter to panicles, and some related factors in high yield...
Using the materials in the previous report, factors determining winnowed hulled 1000 kernel weight (WHTKW) of the primary (PRB) and secondary rachis branch (SRB) at different parts on an ear in line 9...
