EFFECT OF GENOTYPES ON THE YIELD PERFORMANCE OF WHEAT (Trilicun, aestivum L.)

Abstract

The experiment was conducted at the experimental [kid of Sher-e-l3angla Agricultural University, Dhaka during the period from November 2008 to March 2009. Seeds of 19 genotypes of wheat were sown on November 30 to determine their relative performanec on the yield and yield components. The experiment was laid out in randomized complete block design (RCBI)) with three replications. l'he highest yield (3.32 t ha1) was obtained in the variety Gourab and the lowest in Pavan-76(2.64 t ha'). In respect of yield the sequence of genotypes in Gourab? 13L-1022>Suti> kolyan Sona> BAW- 1104> BL- I 883~:BA W- 1051 >I3AW-9 17> BA W- 1064> Prodip> Bijoy> lVT-9> Sonora> Sourab> Shatahdhi?IVT-10> Flag-66> Kanchan> Pavan-76. Ciourab produced the higest yield. It also produced the highest weight of 1000 seeds (49.1Og) which was statistically similar (48.62g) to Kolyan Sona and the lowest weight (36.98g) was found in Pavan-76. The maximum number of spike lets per spike (19.73) was found in Prodip. while the m'nimum number (15.30) was recorded in IVT-10. Results revealed that the genotype which produced the highest yield that also produced best yields components characters. Low yielding genotype produced decreased leal' area. Tl)M. Fewer fertile spike let. Genotypes Gourab and BI.-1022 showed better performance over the others in respect of growth. reproductive, yield and yield contributes characters among the genotypes tinder study.
