Abstract
Performance of sunflower (Helianthus annuus L.) genotypes morphological and yield traits under water deficit conditions
Highlights
Sunflower (Helianthus annuus L.) is the world's more valuable crop and have achieved prestige among all oilseed crops
The sunflower seed cake used for cattle feed and used in industry for making paints, cosmetics, decorations, medical uses [3, 4] and its dried stalk used for fuel [5].The water is getting less day by day, because nonavailability of natural rainfall, too much draw out of groundwater, rise in the number of inhabitant and greater water usage for farming [6,7,8,9].Drought stress is the key factor has destructive effect on the production and oil seed quality [10], modify plant development, physiology and metabolic functions [11]
The obtained result is described here under which are as under Analysis of variance for yield and physiological traits The analysis of variance (Table 1) and separate ANOVA of non-stress and water stress (Table 2) showed that treatment and genotypes were significant for all traits such as flowering days, maturity days, height, head size, seeds head-1, thousand seed weight, relative water content, leaf area, biological yield, head mass, mass of achenes head-1 and harvest index
Summary
Sunflower (Helianthus annuus L.) is the world's more valuable crop and have achieved prestige among all oilseed crops. This is growing and profitable at small farm and large field scale [1] This is called high-grade oil because it contains protein 2027%, huge source of vitamins A and D, oleic acid (16.2%), linoleic acid (72.5%) and greater amount of polyunsaturated fatty acid (60%), make it excellent edible vegetable oil (Tahir et al, 2014), have anti-cholesterol properties, the ability to fit change circumstances, short period, vast adaptation towards soil and climate patterns, photo and thermo-insensitiveness, drought resistant gives maximum oil production per unit area. Plants are tolerant to water deficit, so when exposed to drought stress duration the key developing and flowering stages, production and oil content decreased [19, 20]. The present study is planning to evaluate yield performance of sunflower genotypes under water deficit conditions
