Additive Genetic Effects

An understanding the nature and relative extent of gene actions and combining ability is useful for a breeder to develop superior rice hybrids. In this association, an attempt was made to identify good general and specific combiners for selecting better parents and better cross combinations for developing high yielding and short duration rice hybrids. Four cytoplasmic male sterile lines viz., IR69625A, IR70368A, IR58025A and IR79575A were crossed with ten elite testers, 40 hybrids along with their fourteen parents were evaluated for grain yield and its related traits at the experimental farm of Rice Research and Training Center, Sakha, Kafr El-Sheikh, Egypt, during the rice-growing seasons of 2018 and 2019. The differences among genotypes, parents and crosses were highly significant for all studied traits. The specific combining ability (SCA) played the major role in determining inheritance traits, revealing that the largest part of the total genetic variability associated with most traits was a result of non-additive gene action. The parental line, IR58025A was demonstrated as a great general combiner for grain yield per plant and most of yield components and therefore could be utilized in future breeding programs to improve grain yield. HHZ12-SAL8-Y1-SAL1, HHZ5-Y7-Y2-SUB1 and HUA564 were seen as a good general combiner among testers for grain yield per plant and some studied traits. Four crosses, namely IR58025A / HHZ8-SAL9-DT2-Y2, IR70368A / WEED TOLERANT RICE1, IR70368A / HHZ12-SAL8-Y1-SAL1 and IR70368A / HHZ5-Y7-Y2-SUB1 exhibited significantly good specific combining ability effects for grain yield per plant. Hence, it can be seen that non-additive genetic effects are controlling the inheritance of the studied traits and indicated that selection for the traits inherited with this manner should be performed in the further generations.

Combining ability effects were estimated for grain yield and some other important agronomic traits of maize in a 7×7 diallel analysis excluding reciprocals. The variances for general combining ability (GCA) were found significant for yield, days to pollen shedding, days to silking and ear height while it was found non-significant for plant height and number of kernels/ear. Non-significant general combining ability (GCA) variance for plant height and number of kernels/ear indicates that these two traits were predominantly controlled by non- additive type of gene action. Specific combining ability (SCA) was significant for all the characters except yield and days to silking. Non-significant specific combining ability (SCA) variance for yield and days to silking suggests that these two traits were predominantly controlled by additive type of gene action. Both GCA and SCA variances were found significant only in days to pollen shedding and ear height indicated the presence of additive as well as non additive gene effects for controlling the traits. However, relative magnitude of these variances indicated that additive gene effects were more prominent for all the characters studied except days to silking. Parent BIL95 was the best general combiner for both high yield and number of kernels/ear and parent BML4 for dwarf plant type. Two crosses (BML4× BML36 and BIL114× BIL31) exhibited significant and positive SCA effects for grain yield involved low × average and average × average general combining parents. The range of heterosis expressed by different crosses for grain yield and days to silking was from -65.83 to 21.26 percent and -17.85 to 8.22 percent, respectively.. The better performing three crosses (BIL114×BIL31, BIL138×BIL95 and BIL31×BIL95) can be utilized for developing high yielding hybrid varieties as well as for exploiting hybrid vigour.Bangladesh J.

Combining ability for grain yield and its component characters in rainfed upland rice (Oryza sativa L.) were studied during Kharif 2014 using half diallel involving ten parents viz., VL Dhan 221, Vivek Dhan 154, VL 30240, VL 7620, VL 30560, VL 8116, VL 8549, VL 8724, VL 8732 and Sukradhan1. Both general combining ability (gca) and specific combining ability (sca) variances were found to be highly significant for the characters viz., plant height (gca=85.42; sca=23.12), days to 50% flowering (gca=101.61; sca=42.61), days to maturity (gca=90.37; sca=37.73), tillers per plant (gca=4.63; sca=1.38), panicle per plant (gca=2.36; sca=0.90),kernel length (gca=28.88; sca=23.61), kernel width (gca=1.64; sca=1.92),1000 grain weight (gca=3.60; sca=4.91), grain yield per plot (gca=8.57; sca=3.03), fertile grains per panicle (gca=690.67; sca=300.95) and grains per panicle (gca=1050.58; sca=437.75) indicating the importance of additive and non-additive gene actions in the expression of these traits. However, predominance of non-additive gene action was recorded for all the characters. Parents VL Dhan 221, VL 7620, VL 30560, Sukradhan 1 were good general combiners for grain yield and related characters. VL Dhan 221 and Vivek Dhan 154 were good general combiners for plant height and earliness. On the basis of specific combining ability effects, cross combinations Vivek Dhan 154 x VL 8549, VL 7620 x VL 30560, VL 8549 x VL 8732, VL 30560 x VL 8116 and VL 30240 x VL 8116 were the best specific combiner for grain yield per plot and other associated characters viz., plant height, days to 50% flowering, days to maturity, kernel length and kernal width.

Combining ability on grain yield and its components from line × tester analysis of thirty rice hybrids (Oryza sativa L.) produced by crossing three newly developed CMS lines and ten testers of local origin were studied. The analysis revealed higher SCA variance than GCA variance for all the characters except plant height indicating the prevalence of non-additive gene action. The line KCMS 45A and testers MSN 36 and KMR 3 were the good general combiners for yield and its major contributing characters. MSN 99 was the only good general combiner among the male parents for earliness and dwarfness. The hybrids KCMS 46A × MSN 75, KCMS 44A × KMR 4 and KCMS 45A × KMR 3 were identified as potential hybrids for yield contributing characters based on SCA effects which could be exploited in future rice breeding programme by adopting heterosis breeding strategy. The contribution of testers towards the total variance was found higher than lines and line x tester interaction suggesting predominant of testers influence for these characters.

General and specific combining ability effects were estimated from a 5 line × 8 tester crosses to explore the genetic behavior of CMS and restorers in rice. The variance for GCA and SCA showed predominance of non-additive gene action for all the ten morpho-physiological traits. The estimates of GCA effects revealed that none of the parent was general combiner for all the traits in desired direction. Gan46A and BR827R were good general combiners for higher grain yield coupled with earliness, and IR46R and BR168R was good general combiner for grain yield and lateness in maturity. Good x poor general combiners (Gan46A × Gui99R) for grain yield produced the best specific cross for higher grain yield coupled with earliness, longer panicle, panicles/plant, filled grains/panicle and less sterility (%). Additive × additive, additive × dominance and dominance × dominance gene interactions were involved in deriving good specific cross for grain yield.DOI: http://dx.doi.org/10.3329/bjpbg.v20i1.17013

An insight knowledge nature and relative magnitude of gene actions involved and combining ability is useful for a breeder to assess nicking ability in self-pollinated crops. In this connection, an attempt was made to esti- mate the gene action and combining ability of 70 newly developed CMS based heterotic rice hybrids developed from ten newly developed CMS lines and seven testers were evaluated for grain yield and its components at Hybrid rice scheme, ZARS, V. C. Farm, Mandya. Among the lines, CMS 2 had significant gca effects at 1% level of significance in desired direction for four traits viz., panicle weight, pollen fertility, spikelet fertility and number of spikelets per pan- icle. Out of seven testers, KMR 3 found to be good general combiner for five traits viz., days to 50 per cent flower- ing, plant height, number of tillers per plant, number of panicles per plant and grain L/B ratio. Among the 70 hybrids, CMS1 × KMR3 was good specific combiner for grain yield per plant and grain L/B ratio. It further revealed that SCA variances were higher than the GCA variances for all the characters which indicated preponderance of non-additive gene action. Hence, CMS 2 and KMR 3 are identified as promising lines which can be used in further breeding pro- gramme.

The experiment was conducted to study general and specific combining ability (GCA and SCA) and to estimate heterosis estimation at experimental farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during T. Aman, 2006 and 2007 seasons. Eleven rice parental lines consisting of two quasi CMS lines in BC3 generation  as lines and nine restorer lines  as testers  along with their eighteen F1s and a check variety (BRRI dhan37) were used for combining ability study in a line x tester mating design for eight characters. Ratio of general combining ability (GCA) to specific combining ability (SCA) variances above unity were observed for 1000-grain weight(g) indicating predominance of additive gene action for controlling the character. Among mother parents, CMS-1 appeared as good general combiner for panicle length, 1000-grain weight(g), and grain length–breadth ratio. Among male parents, Benaful, Oval Tapi and Sorukamini-1 were observed to be good general combiners for most of the characters studied. The cross combinations, CMS-1 × Kataribhog, CMS-2 × Maloti-1 and CMS-2 × Keora were found as good specific combiners for most of the characters under study. Good specific combiners were evolved from all kinds of combinations of general combiners indicating additive and non-additive types of gene effect for inheritance. Maximum hybrids showed desired significant standard heterosis for panicle length and 1000-grain weight. None of the hybrids showed desired and significant standard heterosis simultaneously for any three or more characters.

A study was conducted for estimating combining ability and standard heterosis for grain yield and various agromorphological traits involving 10 parents and their 45 F1s (half diallel) during 2012-13 and 2013-14. The results of present investigation revealed that additive gene action played a predominant role in the inheritance of most of the traits under study. On the basis of general combining ability (GCA) effects and specific combining ability (SCA) effects, three parents (Vallabh Basmati 21, Pusa Basmati 1, CSR 13) and three crosses (Vallabh Basmati 21 x Pusa 1121, Pusa 1121 x CSR 13 and Pusa Basmati 1 x CSR 13) were found good general and specific combiners. The best combinations mostly involved good x good and good x poor parental GCA effects suggesting that there is addi-tive x additive and additive x dominance type of gene action for yield and other component traits. The cross showing additive gene action can be improved by pedigree breeding and selection can be postponed to later generations. The most appropriate breeding method for the exploitation of non additive gene action will be heterosis breeding. The six best cross combinations (Vallabh Basmati 21 x CSR 30, CSR 30 x CSR 13, Vallabh Basmati 21 x CSR 13, CSR 30 x Pusa basmati 1, Pusa basmati 1 x CSR 13 and Vallabh Basmati 21 x Pusa basmati 1) had significant standard heterosis for grain yield and other component traits. The crosses which showed significant standard heter-osis is highly suitable for commercial exploitation of heterosis in rice crop.

Information on combining ability is derived from data on twelve yield and yield contributing characters in fifteen male and three female parents utilised in line x tester fashion to estimate combining ability of rice genotypes under coastal saline condition. Forty Five hybrids generated from crossing three lines with fifteen testers were studied along with their parents for combining ability and gene action involved in the expression of characters in rice. The gca and sca effects were significant for all the characters. The magnitude of sca variance was higher than the gca variance for all the characters revealed the presence of predominance of non-additive gene action for all the characters under study. Halchal (-12.29) was found to be good general combiners for days to 50% flowering and early maturity, Halchal (-13.39). However, IR-24 (1.88) was good general combiners with significant positive effect for tallness. Magic (-12.05) good general combiners for dwarfness and Shriram 434 (1.57) was good general combiners for test weight however, Moti was best general combiner with gca estimates of 7.07 for harvest index and Kuber (3.48) was the good general combiners for yield/hill. Cross combinations RHR 27 x IR 24 (4.04) was significant and positive effect for yield/hill, performance for ear bearing tillers per plant were RHR 27 x IR 24 (1.88). In general, the crosses showing significant and desirable combining ability effects were associated with better per se performance for the respective traits. These hybrids could be utilized in heterosis breeding to exploit hybrid vigour.

This study was undertaken to assess the combining ability of 6 rice varieties, for viscosity parameters and determining gene action controlling Rapid Visco Analyser (RVA) characters. F2 progenies derived from a 6×6 half diallel mating design with their parents were grown in a randomized complete block design with three replications at the research farm of Rice Research Institute of Iran (RRII) in 2015. The diallel analysis by Griffing`s method indicated the involvement of additive and non-additive gene actions controlling RVA traits. For traits PV and FV RI18447-2 and IR50 were the best combiners for increasing and decreasing, respectively. Deylamani and IR50 were the best combiners for increasing and decreasing BV, respectively. Beside, due to more portion of non-additive gene action in controlling trait SV, The Gilaneh × RI18430-46, and Deylamani × RI18430-46 crosses were the best for increasing and decreasing SV, respectively. The high estimates of broad sense heritability and narrow sense heritability for BV and FV, indicated the importance of additive effects in expression of these traits. Therefore, selection base breeding methods will be useful to improve these traits and selection in the early generations could be done to fix the favourable genes. Low estimate of narrow sense heritability for SV revealed that non-additive gene effects play important role in controlling setback viscosity. So, hybrid base breeding methods will be useful to improve this trait.

Seventy five hybrids generated from crossing three cytoplasmic male sterile lines with 25 testers were studied along with parents for combining ability and gene action involved in expression of characters in rice. The GCA and SCA effects were significant for all the characters except seedling height, indicating the importance of both additive and non additive genetic components. The ratio of gca and sca variance was less than unity for all the characters also indicated preponderance of non additive genetic variance and suggested good prospects of the exploitation of variation through hybrid breeding. Amongst the parental lines, UPR-2080-24-1-R, IR-60076-1-R, PNR-165-10-6-R and IR-58025- A were found to be good general combiners which can be taken up to generate desirable segregates for further selection. None of the crosses showed significant sca effects for all the characters. On the basis of per se performance and high sca effects, IR-58025-A x CSRC-50-2-1-4-BR, PMS-10-A x IR-42688-2-118-6-3, RPMS-100-A x UPRI-92-79-R and NMS-4-A x IR-32419-28-3-1-3-R were good specific combiners for grain yield plant-1 and their components which could be used for exploitation of heterosis for yield.
