This research aimed to determine the potentiality of P1 and P2 as parents to produce superior strains of hybrid cacao by estimating general combining ability (GCA) and specific combining ability from crossed diallel among high yielding parents which are resistant to P. palmivora. The study was conducted at the Experimental Farm Sumber Asin, Malang, East Java, from 2010 to 2018. The research was arranged in Randomized Block Design (RBD) consisted of 10 hybrids and 5 parents so that the treatment used 15 genotypes. Each treatment consisted of 12 plants in triplicates. Resistance test on parents and F1 showed that all crossed combination strains were infected by pod rot disease (P. palmivora) with various intensity. The highest disease intensity was a strain combination of DR 1 x ICS 13 and the lowest one was ICS 13 and SCa 6. All crossed combination strains in the field had not shown symptoms of any pest infection. Cacao clones that have low GCA value based on the disease intensity were TSH 858, ICCRI 3 and SCa 6. These clones have the potential to be used in the assembly of disease-resistant and high-yielding cocoa hybrids in the future.

Background: The development of superior hybrids is must to break the existing yield plateau ( less than 800 kg/ha) in pigeonpea and hence, the genetic mechanism governing the heterosis in pigeonpea must be decoded. Methods: The present study was laid down using randomized block design during kharif 2018-19 at GBPUAT, Pantnagar with 36 genotypes (8 parents and 28 F1 hybrids) of pigeonpea. The estimates of combining ability were evaluated by using the Griffing’s, Method II, Model I. The observations recorded for yield and related traits were subjected to the estimation of genetic diversity (GD) using the D2 statistics. The correlation between heterosis and different parameters viz., parental mean (PM), specific combining ability (SCA), mean of general combining ability (MGCA) and genetic diversity (GD) were estimated by using Pearson’s correlation. Result: High estimates of SCA variance and more than unity ( greater than 1) average degree of dominance for all the characters indicated the presence of over dominance. The SCA followed by MGCA were found to be most reliable parameters to predict the heterosis. The parents having high x low or high x high per se performance, good x poor GCA effects and with medium genetic diversity resulted in high frequency of heterotic hybrids.

Line x tester analysis using a set of four females, ten males and their forty hybrids was carried out to esti-mate the general combining ability of parents and specific combining ability of hybrids for yield and ten other associ-ated components in rice (Oryza sativa L.) in a Randomized Block Design during Kharif 2011. GCA variances for females (s2f) were significant at 0.1% level of significance for plant height (40.8), no. of grains per panicle (505.9), grain yield per plant (29.1), test weight(17.9), straw yield per plant (61.3) and kernel L/B ratio (0.2) whereas specific combining ability (SCA) variances for f x m interactions were highly significant for all the characters. Non-additive gene action was prevalent in all characters (Range: 0.03 in amylose content to 0.88 in kernel length breadth ratio) except plant height (1.33) as evident by low GCA to SCA ratio. None of the parents were good general combiner for all traits, however, female IR-28 and male AMT-119 and PNR-546 were good general combiners for a maximum number of traits i.e. five traits out of eleven.. The general combining ability for grain yield per plant for female parent Gurjari (6.19) and NVSR-178 (5.29); and male parents AMT 119 (2.73) and PNR 546 (2.44) makes them a good choice for improving yields in a hybridization programme as these female and male parents are also having signifi-cant GCA effects for maximum number of yield associated traits i.e. four and five traits out of eleven for female and male parents respectively. A vis-à-vis comparison of top three specific combining ability crosses with their mean performance showed correlation and these crosses were having at least one good general combining ability parent.

Present investigation was carried out during autumn winter season 2013-14 and 2014-15 at the Vegetable Research Centre of GBPUA&T, Pantnagar with 43 genotypes including 10 lines, 3 testers and 30 F1’s of brinjal. The experiment was laid out in Randomized Block Design with three replications. The observations were recorded for 11 characters. Variances due to testers were greater than variances due to lines for most of the characters. The estimates of General Combining Ability (GCA) effect indicated that PB71, BB85, PB66, Swarn Syamli and DBL02 were best general combiner for earliness (days to 50% flowering), whereas the best specific cross was BRLVAR6 × DBL02. For weight of marketable fruits per plant PB66, SMB115, LC7, BRLVAR6 were best general combiners and SMB115 × DBL02, PB66 × Pant Samrat and IBWL 2001-1 × Pant Rituraj were best specific combiners. Pant Rituraj was found best general combining effect for plant height, fruit diameter, weight of marketable fruits per plant, number of unmarketable fruits per plant, total yield per plant and total yield per hectare. Pant Samrat showed good General Combining Ability (GCA) effects for number of primary branches per plant, number of marketable fruits per plant, weight of unmarketable fruits per plant and total number of fruits per plant. DBL02 was recorded best general combiner for earliness and fruit length. SMB115 and PB 66 were best general combiners for most of the yield characters. SMB115 × DBL02, PB66 × Pant Samrat and IBWL2001-1 × Pant Rituraj were showed highest Specific Combining Ability (SCA) effect for most of the characters. Therefore, these cross combinations could be commercially exploited for higher yield.

Combining ability estimation is an important genetic attribute for maize breeders in anticipating improvement in productivity via hybridization and selection. This research was carried out to investigate the genetic structure of the 27 F1 maize hybrids established from nine lines derived from Maize Research Department and three testers, to determine general combining ability (GCA), determine crosses showing specific combining ability (SCA) and superiority percentages for crosses. Nine lines, three testers, 27 F1 hybrids and two check commercial hybrids (SC162 and SC168) were studied in randomized complete block Design (RCBD) with three replications during 2016. The results of mean squares showed that significant and highly significant for most studied traits (days to 50% tasseling, days to 50% silking, plant and ear height, ear position, ear length, no. of kernels per row, 100-kernel weight and Grain yield). Estimates of variance due to GCA and SCA and their ratio revealed predominantly non-additive gene effects for all studied traits. Lines with the best GCA effects were: P2 (line 11) and P6 (line 21) for grain yield, for testers Gm174 and Gm1021 had significant GCA effects for grain yield. The hybrids P5×Gm1021, P6×Gm1021, P7×Gm1021, P8×Gm1002, P9×Gm1002 had significant and negative SCA effects for grain yield. Crosses P1×Gm174, P2×Gm1002, P5×Gm1021, P6×Gm174, P6×Gm1021, P7×Gm1021, P8×Gm1002, P9×Gm1021 were the best combinations manifested and significant superiority percentages over than check varieties (SC162 and SC168) for most studied traits. Therefore, these hybrids may be preferred for hybrid crop development. Abbreviations: GCA general combining ability; SCA specific combining ability

It was studied the performance of each of group of lines based on their combining ability to determine the best hybrids. We also estimated usefull heterosis in the traits under study. 23 lines were crossed with two testers and evaluated in 1995 in a experiment with two replications in two locations in Veracruz, Mexico. A complete block design with factorial arrangement was utilized. Lines were consideredas factor A while testers were considered as factor B.  Results indicated that the average performance of lines, testers and lines x testers turned out to be statistically different for flowering date, plant height, prolificy and yield. Lines 37 and 7 standout with 9.473 and 9.203 t/ha, respectively. Outstanding hybrids showed yields between 9.173 to 9.685 t/ha and included lines 7, 15, 17, 37, 39 and 49. The highest heterosis and best specific combining ability (SCA) were found out in the cross between line 17 x tester 1 with 18,34 % for yield and line 37 was best for general combining ability (GCA) (0,52). Heterosis for flowering date was of -7,27 % and outstanding for their ACG the lines 14, 15, and 39. For prolificy the  31 was best than any other line with 52 % of heterosis and ACG too and for ACE the cross of the 17 x tester 1 was superior (6,28).
