“…The importance of hybrid cultivars in sunflower has increased recently because of their higher seed yield compared with cross-pollinated varieties in many countries in the world. Hybrids of sunflower are more stable, highly self-fertile, with high yield performance, and more uniform at maturity (Kaya and Atakisi, 2004;Seetharam, 1979;Sujatha et al,2002). Resistance to diseases and Orobanche has also increased the importance of hybrid varieties.…”

“…The heterotic performance of a hybrid combination depends upon the combining abilities of its parents (Allard, 1960;Kadkol et al, 1984). Kaya and Atakisi (2004) reported that superior hybrids have been obtained by crossing cytoplasmic male sterile inbred (CMS) female and restorer lines with high general combining ability (GCA) and specific combining ability (SCA) values. General combining ability refers to the average performance of parental lines as reflected in its hybrid combinations and specific combining ability refers to the average performance of a particular cross.…”

Eight lines and six testers of sunflower were crossed using line x tester method. The 48 F1 single cross combinations along with their parents and two checks were planted in simple lattice design with two replications. The results of analysis of variance showed significant differences among the genotypes for all the traits including plant height, head diameter, life-cycle duration, grain yield, 1000 seed weight, oil content and oil yield. Line x tester analysis revealed significant effects of genotypes, hybrids and interaction effects of line x tester for all the studied traits. The testers including RF81-25 and RF81-30 with significant positive general combining ability (GCA) effects for grain yield and 1000 seed weight respectively and also RF-131/1 with significant negative GCA effect for plant height were considered as good combiners and also the lines including AF80-488/1/2/1 and AF80-488/2/1/1 were good combiners for grain yield and 1000 seed weight respectively. The crosses including AF80-460/2/1/1 x RF81-25 and AF8-6937 x RF81-30 had significant positive specific combining ability (SCA) effects for grain yield, oil content and oil yield. Estimating low narrow sense heritability for all the traits indicating the importance of non additive genetics effects for them, so for improving these traits hybrid method will be effective.

“…Overall, The female parents (lines) had a large proportion in the expression of traits than male parents also affirms the role of cytoplasmic and nuclear interactions in the expression of these traits. This also shows the importance of plant material diversity used for similar studies [53]. Similarly, significant GCA effect for seed yield was stated in the previous studies in that parent which were good general combiners for economic traits might be extensively used in hybridization programs to identify suitable parents for hybridization and developing potential hybrids for seed yield [54,55].…”

Sunflower is sensitive to drought and its hybrids have a limited cytoplasmic diversity. The wild 10 cytoplasmic sources of sunflower are not well exploited to their potential for drought tolerance and hybrid 11 development. In this respect, we carried out a Line × Tester based genetic study using 19 sunflower 12 genotypes representing, 13 cytoplasmic male sterile (CMS) lines from wild and conventional sources, 2 13 maintainer lines, and 4 restorer lines. The CMS and maintainer lines were crossed with restorer lines to 14 develop sixty one-way F1 hybrids. The parents and their hybrids were evaluated under two water 15 regimes viz., normal irrigated and water stress. A total of twelve important plant descriptors were studied 16 over a period of two years. The significant differences were observed between parents and hybrids in both 17 water regimes. Hybrids were higher in average values for all the descriptors than parents. The role of 18 female parent was more prominent in the expression of traits in hybrids as compared to male parents. The 19CMS sources varied significantly regarding seed yield per plant and other physiological traits. Proline 20 content was three times higher in parents and their hybrids under water stress, and it was not correlated 21 with any other descriptor. Accession CMS-PKU-2A was identified as the best general combiner for leaf 22 area and specific leaf weight. Whereas, CMS-234A was the best general combiner for biological yield and 23 photosynthetic efficiency under both the conditions. The cross combinations CMS-ARG-2A × RCR-8297, 24 CMS-234A × P124R, and CMS-38A × P124R were found significant for biological yield, seed yield and oil 25 content under both environments. Overall, this study provides useful information about the cytoplasmic 26 effects on important sunflower traits and drought stress tolerance when used in the different 27 combinations. 28 29 30 1. Introduction 31 Sunflower (Helianthus annuus L.) is a commercially important oilseed crop, and its oil is 32 comparable to virgin oil olive for health promoting benefits [1,2]. Botanically, sunflower is a cross-pollinated 33 and self-incompatible plant [3]. Moreover, it out crosses freely with its wild relatives [4]. During the past few 34 decades, the area and production of sunflower have increased because of its day length neutrality, a wider 35 adaptability, and responsiveness to added inputs [5]. Similarly, these attributes of sunflower promote 36 sustainable crop production system when sunflower is used with other crops in crop rotation [6]. The central 37 component of sunflower breeding is the development of hybrids through cytoplasmic male sterility (CMS) 38 system [7]. CMS is the absence of fertile pollen in the plant hence eliminates the need for manual 39 emasculation for the development of a successful cross combination. CMS based hybrids system has been 40 extensively distributed throughout the plant kingdom and well exploited for achieving yield targets, disease 41 resistance, and drought tolerance [8-10]. 42CMS syst...

“…En los casos donde el efecto de ACG fue mayor al de ACE es recomendable hacer selección de genotipos con dichas cualidades y utilizar al menos a uno de ellos como progenitor en programas de cruzas simples, ya que según Reyes et al (2004), una cruza simple con al menos uno de sus progenitores con alta ACG puede garantizar altos valores en el rasgo evaluado. Valores significativos de ACG en componentes de rendimiento también han sido reportados para gerbera (Harding et al, 1981b) y otros cultivos como girasol (Helianthus annuus L.) (Kaya y Atakisi, 2004;Machikowa et al, 2011), tomate de cáscara (Physalis ixocarpa Brot.) (Camposeco et al, 2015), chile (Capsicum sp.)…”

Los cultivos que cuentan con un número considerable de variedades cultivadas, como la gerbera (Gerbera × hybrida), pueden ser evaluados mediante experimentos de cruzas dialélicas para la formación de nuevos híbridos. El objetivo de la presente investigación fue estimar la aptitud combinatoria general (ACG) de seis variedades de gerbera y la aptitud combinatoria específica (ACE) de sus cruzas dialélicas, así como la heterosis en componentes de rendimiento y calidad de flores. Se empleó el método 1 de progenitores y sus cruzas F1 directas y recíprocas con el modelo II de efectos aleatorios de Griffing. La evaluación se realizó bajo un diseño experimental de bloques completos al azar con cuatro repeticiones. El análisis estadístico detectó diferencias significativas (P ≤ 0.01) dentro y entre progenitores y cruzas, así como en las interacciones, lo que evidenció amplia variabilidad entre progenitores y efectos maternos significativos por herencia citoplásmica. Los mayores efectos de ACG (P ≤ 0.01) para rendimiento de tallos florales lo tuvieron los progenitores IGL, MG2 y FAS, mientras que los mayores efectos de ACE los mostraron las cruzas FAS × JES, ALC × IGL y DIN × IGL. Se encontraron efectos positivos de heterosis para rendimiento en las cruzas FAS × IGL, JES × IGL, ALC × IGL, DIN × IGL, MG2 × IGL y FAS × MG2. Los resultados sugieren que Igloo y Fascination pueden ser utilizados como progenitores superiores en programas de cruzamiento para desarrollo de nuevas variedades de gerbera. Los valores altamente significativos de ACG para rendimiento de flor indican la importancia relativa de la acción génica aditiva sobre los efectos no aditivos.
