“…This indicated the presence of considerable genetic diversity among the parents (lines and testers) used in the present study. The line, Kashmir Sel-1 (L 2 ) was the good general combiner for earliness followed by the lines, UHFSP ( Rao PG et al 2016. In some of the crosses, significant specific combining ability effects were observed but, they had both the parents as poor general combiners.…”

Abstract:The present investigation involves 29 diverse bell pepper genotypes for variability studies and 14 promising lines (11 lines and 3 testers), 33 F 1 and 1 standard check for combining ability studies. The objective of the study was to assess the nature and magnitude of genetic variability among the bell pepper genotypes for yield and other horticultural traits and to identify the potential parental lines and cross combinations suitable for the protected environment based on the estimation of general combining ability and specific combining ability. A wide range of variability was observed for most of the characters studied. The genotypes viz., Kashmir Sel-1 (L 2 ), DARL-10 (L 9 ) and UHFSP(Y)-11 (L 11 ) for marketable fruit yield per plant and Kashmir Sel-1 (L 2 ), UHFSP(Y)-11 (L 11 ) and DARL-01 (L 5 ) for earliness were good general combiners and these may be included for exploiting hybrid vigour or development of purelines. On the basis of specific combining ability effects and per se performance, the crosses viz.,

“…Sharma and coauthors [43] reported that the F1 hybrids namely Rani Sel-1 × SSP, Rani Sel-1 × Sel-12-2-1, SSP × SP-316 and PRC-1 × California Wonder showed significant better parent and standard heterosis for marketable fruit yield plant -1 in bell pepper. Rao and coauthors [44] were found hybrid viz. Akra Mohini × IIHR-4107 exhibited the highest standard heterosis for fruit number (77.27%).…”

One nuclear male sterile (NMS) line of chilli pepper and eight elite inbred lines of bell pepper were evaluated in a line × tester mating design to project heterotic F1's through studying plant growth and yield performance of developed hybrids in relation to phenotypic distance between their parental lines. Hybrids and their parental lines were grown and evaluated under poly-net house conditions at the Punjab Agricultural University, Ludhiana, India during the years 2017-2019. Pooled over the year, mean squares (MS) due to genotypes was recorded significant (p=0.05) for all the traits studied, suggesting that there existed significant differences among the genotypic means that included nine parental lines and their eight F1 hybrids. The MS due to the G × Y interaction effects were also significantly different for plant growth and fruit traits, indicating differential response of each genotype in the year. On the basis of heterotic performance, the hybrids namely MS-12 × PAU SM-31 had positive significant mid-parent heterosis (MPH) for total fruit yield plant -1 (96.68**), number of fruits plant -1 (51.98**), pericarp thickness (47.91**), fruit length (25.77**), and plant height (63.35**). Apart from this cross-combination, the hybrids MS-12 × PAU SM-3 and MS-12 × PAU SM-9 also depicted MPH for total fruit yield plant -1 (71.22** and 50.64**), fruit length (41.98** and 68.09**) and number of fruits plant -1 (27.60** and 44.73**). Based on better parent heterosis (BPH), the hybrid MS-12 × PAU SM-HIGHLIGHTS  The effect of phenotypic distance between parental lines on the yield of C. annuum var. annuum × C. annuum var. grossum F1 hybrids was assessed. Simultaneously, the target of the research was transferring of the GMS ms10 gene from hot pepper to heat tolerant bell pepper inbreds. Over the BP, the hybrid MS-12 × PAU SM-31 was found to be superior in respect of total fruit yield plant -1 and pericarp thickness. 2 Rani, M.; et al.

“…Considering the standard heterotic effects, the number of crosses having significant heterosis in desired direction is more than that of the crosses with heterosis in undesired direction for most of the traits is strongly suggesting that the genes with desired effect were dominating. The negative heterosis are seen in some of the crosses may be based to non-allelic interaction which can either increase or decrease the expression of heterosis (Rao et al, 2017). Heterobeltiosis rates for TSS on F1 changed from -35.82 to 18.44%.…”

“…The predictability ratio revealed overwhelming response of non-additive gene action in controlling theexpression of fresh fruit yield per plant and most of the yield components. Rao et al (2017) determined heterosis rates in terms of yield and some characteristics affecting yield in 33 hybrids obtained by using 3 lines and 11 testers in bell pepper. Accordingly, the highest heterosis rates were determined as 77.27% for fruit number per plant, 131.82% for fruit weight per plant, and 43.72% for average fruit weight.…”

Amaç: Bu çalışmanın amacı, kapya tipi kırmızı biberin verim, toplam çözünür madde ve kuru maddesi üzerine heterosis, heterobeltiosis ve dominans etkisini belirlemektir. Yöntem ve Bulgular: Çalışmada 11 kapya tipi kırmızı biber ebeveyni ve bu ebeveynlerin melezlerinden elde edilen 47 hibrit materyal olarak kullanılmıştır. Meyve verimi yönünden heterosis oranları -48.23 ile 80.68 arasında değişmiştir. En yüksek heterosis sırasıyla 209 YKB (%80.68), 239 YKB (%60.35), 225 YKB (%56.97) ve 195 YKB’de (%55.30) tespit edilmiştir. Toplam çözünür madde açısından heterosis oranları -33.70 ile 30.98 arasında değişmiştir. En yüksek heterosis oranı 218 YKB'de belirlenmiştir. Kuru madde bakımından en yüksek heterosis oranı ise 195 YKB'de %66,67 olarak hesaplanmıştır. Çalışma sonucunda hibritlerde en yüksek heterosis oranları veren ebeveynler genel olarak 39-H-2, 43-H-6 ve 45-H-5 olarak belirlenmiştir. Genel Yorum: Bu çalışmada heterosis oranları her üç özellik açısından da yüksek oranda pozitif yönde tespit edilmiştir. Heterosis kullanımı biberlerde verim ve diğer ekonomik özelliklerin artırılmasında pratik bir yöntem olarak gösterilebilir. Çalışmanın Önemi ve Etkisi: Elde edilen bu sonuçlar istenen özellikler bakımından öne çıkan çeşitlerin belirlenmesinde kullanılabilecektir.
