dc.description.abstractThe present investigation conducted in Rabi 1983 at A.R.S., Dhandhuka, envisages the relationship between different growth and yield attributes in six dry wheat varieties. The six varieties examined were A-206, A-28 G.W.1, G.W. 2, A-9-30-1 and D-1. During the course of experimentation various growth indices and certain physiological parameters were considered. Variety G.W.l recorded highest (1076 kg/ha), varieties A-9-30-1 (780 kg/ha) and D-1 (756 kg/ha) registered moderate and G.W. 2 (592 kg/ha), A-28(573 kg/ha) and A-206 (526 kg/ha) varieties recorded lower grain yield per hectare. Short duration variety G.W.I stood first in grain yield but this was not true for all of the entries. The intact of plant height on grain yield was not clear. Similarly, no conclusion could be drawn from the results on tillers per plant in different varieties. A rough relation between grain yield and test weight was noticed. Similar results were recorded in case of harvest index and grain yield. In general, higher dry matter production during early growth period produced higher yield. Similarly, higher root weight at early growth stages reflected in acre grain yield. On the other hand, association of stem and leaves dry natter accumulation was not clear with the yield. There was decline in RGB and LAR as the season advanced. No definite correlation was observed between RGR and grain yield. A rough relation was noticed between OSR and yield. In general, LAI increased with increase in dry setter. Grain yield increased with increase in LAI. This was very clear during the early growth stage. Similarly, in general, higher LAD values reflected in higher grain yield. No definite relation between grain yield and HAR vas noticed, However, in general, higher yielder varieties such as G.W. l, A-9-30-1, and D-l recorded lower values of NAR. This may be considered as indicative of a rough negative relation between grain yield and NAR. The results of the present investigation indicated that the harvest index, number of spikelets per ear, 1000-grain weight, crop maturity period, dry matter production, CGR, LAI, LAD etc., had more impact on grain production. The degree of their influence on yield may have yield in different varieties at different growth stages.en_US
