“…The comparison of magnitude of general combining ability and specific combining ability variance indicated that the non-additive genetic effects were predominant in the characters, days to 50 % flowering, days to 75% maturity, plant height, branches per plant, number of pods per plant, pod length, number of seeds per pod, biological yield per plant, seed yield per plant, 100 seed weight and protein content, which suggested prime role of non-additive gene action. These results are in line with Gill et al (2014), Prasad and Murugan (2015) and Baradhan and Thangavel (2011) in blackgram, Chuwang Hijam et. al.…”

Background: Urdbean (2n=2x=22), also known as blackgram is an important short duration legume crop belonging to family Fabaceae, widely cultivated in Asia. Urdbean occupies an important position among pulses owing to its high seed protein (25-26%), carbohydrates (60%), fat (15%), minerals, amino acids and vitamins. Owing to its low water requirement, it is also suitable for rainfed conditions. It adapts well to various cropping systems owing to its ability to fix atmospheric nitrogen in symbiosis with soil bacteria, rapid growth and early maturity. Half diallel analysis was adopted in present study to gather information on gca (general combining abilities) and sca (specific combining abilities) of 6 diverse parents and simultaneously estimating various types of gene effects involved in the expression of seed yield and related attributes in urdbean. Methods: The F1’s were developed during 2017 in 9 x 9 half diallel fashion by Sharma et al. 2019 and these F1’s were evaluated. Significant crosses on the basis of gene action and combining ability were selected for further advancement. The experimental material comprised of the six parents and 15 F2’s of a 6 x 6 half diallel cross among six cultivars of urdbean (four are purelines viz., Palampur-93, HPBU-111, DU-1 and KU-553 and rest of the two are advanced and indigenous lines viz., Him Mash-1 and IC-281994). The F2’s along with the parental genotypes were grown in a Randomized block Design (RBD) with three replications at Experimental Farm of the Department of Crop Improvement, COA, CSK HPKV Palampur (H.P.) during Kharif, 2018. Results: The cross combination, Him Mash-1× HPBU-111, was identified the best for high seed yield on the basis of sca. The specific crosses, Palampur-93 × IC-281994, Palampur-93 × KU-553 were good specific combiners for most of the traits viz., plant height, branches per plant, pods per plant, biological yield per plant, seed yield per plant, harvest index, 100-seed weight and crude protein content.

“…Sharma and Jaiswal [25] also observed better results for such valuable characters of wheat. Such results had also been confirmed by Padhar et al [26] and Hijam et al [27] in his experiment working with the crop of wheat on different morphophysiological characters.…”

Climate change is a major threat to most of crops grown globally in sub-tropics and tropics. One of the consequences of climate change is drought, which has a negative effect on crop growth and productivity. However, present research drought affected breed wheat was tested to examine the quality of wheat selection for different stage using morphological and phenological traits. Ten genotypes along with two local check varieties were tested in randomize complete block design were used for this experiment. The experiment was conducted in the field of Southern Wheat Research Station, Agriculture Research Institute, Tandojam, in winter season to determine the different levels of tillers per plant, growth vigor, early growth habit, plant type, Leaf type, content of proline in (μ mol. g-1 fresh wt), osmotic potential in (-Mpa) and relative water content in (%) analyzed for significance. The genotypes showed positive significantly differ in response to studied traits. Ten genotypes were sown in three replications, in two blocks. The genotypes were significantly different in response to the moisture stress. There were highly significant differences for all traits. The positive association for studied the parameters between the ﬁeld trials demonstrated that greater seedling vigor of root and shoot is key factor inﬂuencing in wheat. Therefore, our finding suggested that these genotypes had potential to grow well and perform better than other genotypes and check varieties.

“…In diallel analysis, GCA is a function of additive genetic influences, but it may partly include some dominant effects when the gene frequencies are not equal to one half and/or parents are included in the analysis to estimate variances. However, the SCA is the function of non-additive genetic affects that include dominance and epistatic effects (Hijam et al 2018).…”

This study was conducted during 2018 and 2019 at the Rice Research and Training Centre farm, Sakha, Kafr el Sheikh, Egypt. Six genotypes of rice, Sakha 101, Giza 178, Irat 170, Wab-56-104, IR65500-127 and IR69853 were half-diallel crossed to estimate the combining ability effect as well as sink and yield potential in rice. Sink capacity (number of spikelets/panicle and 1000-grain weight), source leaf (flag leaf length, flag leaf width and flag leaf area), source-sink association (number of spikelets/panicle to flag leaf area ratio) and traits of yield components (filled grains number/panicle and panicle number) plant and grain yield/plant) were analysed. The results indicated that both general and specific combining ability were highly significant for all the studied characteristics. IR65500-127, Giza 178, and Sakha 101 were identified as good parents, so these parents were suggested for a further recombinant breeding programme. The cross of 3 × 5 was found to be superior for flag leaf width and grain yield, while the cross of 1 × 4 was found to be superior for flag leaf length, flag leaf length/width ratio, chlorophyll content and number of panicles/plant. Advancing these crosses and effected selections in segregating generation would be helpful to develop high yielding varieties. The genetic parameter showed a dominant deviation in one direction was controlled for all characters except flag leaf length. The analysis of the regression line showed that the over-dominance played an important role in the inheritance of gene action for grain yield/plant.
