“…While, both the cytosterile sources were equally efficient for per se performance of 100 seed weight, volume weight and hull content as the overall mean of E002 based hybrids and ARG 3 based hybrids were comparable. Comparable results corresponding to these traits were also noted in the studies of Gouri Shankar et al (2006) and Tyagi and Dhillon (2017).…”

The effect of cytoplasm on the mean performance of inbreds and their corresponding hybrids for seed yield and its contributing traits was investigated in the present study. There was no significant difference found between the inbreds based on cytosterile sources E002 (H. annus), ARG 3 (H. argophyllus) and PET 1 (H. petiolaris) for oil content, oil yield and seed yield indicating that under DS 2 nuclear genetic background all the three alloplasmic lines were on par for these traits. Similarly, for the performance of hybrids, both the cytosterile sources E002 and ARG 3 were equally efficient in the expression of traits viz., stem diameter, 100 seed weight, volume weight, hull content and seed yield but showed significant variations for days to 50% flowering, plant height, head diameter, days to maturity, seed filling percentage, oil content and oil yield. However, for per se performance for traits showing significant variation, E002 cytoplasm based hybrids were superior over ARG 3 cytoplasm based hybrids. Even for mid parent heterosis and heterobeltiosis both cytosterile sources influenced traits under consideration with the positive influence of E002 cytoplasm on MPH and BPH for all the traits except plant height and head diameter.

“…Furthermore, in some instances, the negative effects of cytoplasmic and nuclear genome interaction resulted in the reduced chlorophyll content and photosynthetic efficiency [28]. In contrast, a positive effect of nucleus and cytoplasm interaction has also been reported for oil content [29]. Therefore, the influence of cytoplasmic effects on important agronomic traits needs to be understood more precisely.…”

Sunflower is sensitive to drought, and furthermore, sunflower hybrids display limited cytoplasmic diversity. In addition, the wild cytoplasmic sources of sunflower are not well explored for their potential to introduce drought tolerance into newly developed hybrids. Therefore here, we carried out a Line × Tester-based genetic study using 19 sunflower genotypes representing, 13 cytoplasmic male sterile (CMS) lines from wild and conventional sources, 2 maintainer lines, and 4 restorer lines. The CMS and maintainer lines were crossed with restorer lines to develop sixty F1 hybrids. The parents and their hybrids were evaluated under two water regimes, normal irrigation and drought stress (i.e., withholding water). A total of twelve important plant descriptors were studied over a period of two years and the significant differences between parents and hybrids are reported here. More specifically, hybrid lines were higher in average values for all the descriptors. The contribution of female parent was more prominent in the expression of traits in hybrids as compared to male parents. The CMS sources varied significantly regarding seed yield per plant and other physiological traits. Proline content in the leaves of all the genotypes was three times higher in the water stress regime. Accession CMS-PKU-2A was identified as the best general combiner for leaf area and specific leaf weight., whereas CMS-234A was the best general combiner for biological yield and photosynthetic efficiency under both conditions. The cross combinations CMS-ARG-2A × RCR-8297, CMS-234A × P124R, and CMS-38A × P124R were found significant for biological yield, seed yield and oil content under both environments. Overall, this study provides useful information about the cytoplasmic effects on important sunflower traits and drought stress tolerance.

“…runyonii) presented significantly higher yield than the common maintainer line, making them potentially useful to develop efficient water use CMS lines. Furthermore, the effects of cytoplasmic sources on the estimation of combining ability for agronomic traits and stability under different environments were also evaluated (Tyagi and Dhillon, 2017;Tyagi et al, 2018).…”

Plant heat stress transcription factors (HSFs) are involved in the response to heat. In Arabidopsis thaliana the HSFs genes are completely identified, however there was no information available about these genes in Vasconcellea pubescens (Chamburo) until now.In this preliminary work we describe the VPHSFB1 gene of V. pubescens (gene expression evaluated by RT-PCR and the partial sequence) that was induced by the increment of temperature. From our results, VPHSFB1 could be used as a heat response marker gene in tropical species.
