VARIATION OF GRAIN WEIGHT - EAR-1 AND - PLANT-1 AND 1000–GRAIN WEIGHT TRAITS OF WINTER WHEAT (TRITICUM AESTIVUM L.) VARIETIES UNDER THE EFFECT OF DIFFERENT TREATMENTS.
Essien Okon*, Hannah Edim Etta and Vladimir Zuba
This study was carried out to investigate the variation of traits; grain weight ear-1, grain weight plant-1 and 1000–grain weight in three winter varieties namely Batko, Diya and Krasnodarskaya 99 under the influence of the growth regulator, Furolan and mineral fertilizer. The grain weight ear-1 is one of the basic traits of which one could determine with high accuracy productivity or yield of the experimental variant or plot of any of winter wheat variety. Grain weight plant-1 or productivity as it may called, is one of the basic traits of winter wheat varieties, which determines yield. The 1000–grain weight is one of the basic quantitative traits, characterizing yield of the variety, seed and its technological qualities. In the variant treated with mineral fertilizers and growth regulator the grain weight ear-1 obtained was 1.31 g which was 0.12 g more than control (LSD05-variant = 0.01). Similar pattern was observed in the experimental variants of other varieties. The effect of factor C (growth regulator) during the formation of 1000–grain weight formed 5.0%. Furolan influenced the process of the formation of grains of winter wheat varieties during the last stages organogenesis.
