Assessing heritability and variance components of agronomic traits of four alfalfa (Medicago sativa L.) cultivars

Abstract

This research was conducted between the years 1999-2002 in the experimental area of the Field Crops Department of Tekirdağ Agricultural Faculty in Turkey. The experiment was laid out in a randomized block design with three replications. Four alfalfa cultivars were used. Variance components, variance coefficients and heritability values were determined for morphological characters, herbage yield, dry matter yield and seed yield. The maximum main stem height (78.69 cm), main stem diameter (4.85 mm), leaflet width (0.93 cm), seeds/pod (6.57), herbage yield (75.64 t ha -1 ), dry matter yield (20.06 t ha -1 ) and seed yield (0.49 t ha -1 ) were obtained from the cultivar Marina. The leaflet length ranged from 1.65 to 2.08 cm and the raceme length from 3.15 to 4.38 cm in the alfalfa cultivars. The highest 1000-seed weights (2.42-2.49 g) were found in cultivars Marina and Sitel. The heritability values of main stem height, main stem diameter, leaflet length and width, leaf/stem ratio, racemes/main stem, raceme length, seeds/pod, 1000-seed weight, herbage yield, dry matter yield and seed yield were calculated as 91.0%, 97.6%, 81.8%, 88.8%, 90.4%, 28.3%, 99.0%, 99.2%, 88.0%, 97.2%, 99.6% and 95.4%, respectively.

Conversion of rural abattoir wastes to an organic fertilizer and its application in the field cultivation of tomato in India

“…saccharifera Alef.) and spring barley ( Hordeum vulgare L.) cultivations without any harmful effects on the plants (Petróczki, 2004). The present study, to the best of our knowledge, is the first on the application of abattoir waste for cultivation of tomato.…”

Forage Yield and Some Quality Traits of Persian Clover at Winter and Spring Sowing Under Edirne Ecological Conditions, Turkey

“…High quality forage may be obtained from Persian clover cut at all the growing stages . The yield and quality of forage crops are highly influenced by genotype and environment interaction (Ates and Tekeli, 2004). These are the result of the interaction between a genotype's potential expression and the environment, which is modified by agronomic management in order to meet to objectives of the farmer (Mariani and Ferrante, 2017;Golla et al, 2018).…”
