“…Thus, Ingorala 5 and DC 4 were good general combiners for seed yield and its components, and they may be utilized in crossing programme to generate high genetic variability for implied selection to develop high yielding varieties of sesame. These results are in accordance with the findings of Azeez and Morakinyo (2014), Kumari et al (2015), Reddy et al (2015), Tripathy et al (2016), , Ismail et al (2020), Pramitha (2020) and Sikarwar et al (2021).…”

“…Significant specific combining ability in a favourable direction was observed in many crosses for days to flowering (1 cross), days to maturity (1 cross), branches per plant (3 crosses), capsules per plant (2 crosses), locules per capsule (4 crosses), capsules length (4 crosses), seeds per capsule (1 cross), seed yield per plant (3 crosses), 1000 seed weight (5 crosses), harvest index (3 crosses), oil content (2 crosses) and protein content (3 crosses). These results are supported by the findings of Kumari et al (2015), Reddy et al (2015), Tripathy et al (2016), , Ismail et al (2020), Pramitha (2020) and Sikarwar et al (2021).…”

“…The predominance of non-additive gene action for seed yield per plant and its component traits were also reported by Azeez and Morakinyo (2014), Hassan and Sedeck (2015), Kumari et al (2015), Reddy et al (2015), Tripathy et al (2016), Khuimphukhieo and Khaengkhan (2018), Abd-Elsaber et al (2019), ), Ismail et al (2020, Pramitha (2020) and Kumar et al (2021).…”

“…Among parents, DC 4 was superior for 1000 seed weight, oil content and protein content, whereas in the case of hybrids AT 332 x AT 476 and DC 4 x Ingorala The analysis of variance for combining ability for different characters revealed that mean squares due to general combining ability (GCA) were significant for all the characters except days to maturity and specific combining ability (SCA) was significant for all the characters except plant height, capsules per plant and seeds per capsule (Table 3).

Six diverse parents were crossed in a half diallel fashion to study the heterosis and combining ability in sesame. Parents, 15 F 1 s with one check was planted in RBD design at College Farm, NAU, Campus Bharuch during kharif-2021. The mean sum of squares due to genotypes and hybrids were significant for all the traits while, due to parents were significant for most of the traits. The mean sum of squares due to parents vs. hybrids were found to be significant for some traits. The gca and sca ratio was less than unity indicated that non-additive components play a greater role in the inheritance of most of the traits. Parents, Ingorala 5 and DC 4 had high per se and also good general combiner for seed yield and its traits, while hybrids AT 476 x Ingorala 5 and AT 332 x Ingorala 5 had the highest standard heterosis and sca effects for seed yield and some of its traits.

The study deals with the pollen morphology, in vivo pollen germination and pollen pistil interaction in two species of Sesame viz., S. indicum (CO 1, VRI 3, TMV 7) and S. radiatum. As wild species are potential sources of biotic and abiotic stress-resistant genes, strong crossability with cultivated varieties is critical for gene transfer through traditional breeding programmes. The pollen morphology studied under a Scanning electron microscope revealed both species to be stephanocolpate and possessed the shape of prolate. The number of colpi counted assisted in differentiating the pollen of S. indicum from S. radiatum and represented the evolution of the former. The pollen pistil interaction by aniline blue technique between direct and reciprocal crosses of two species of Sesamum reported the pollen germination per cent of S. radiatum × S. indicum (CO1) (85.00) at one hour after pollination, S. indicum (CO1) × S. radiatum (80.00) at one hour after pollination and S. radiatum × S. indicum (VRI 3) (80.35) at two hours after pollination were on par with each other and expressed higher pollen germination per cent, while S. indicum (CO1) × S. radiatum (22.70), S. indicum (VRI 3) × S. radiatum (20.30) and S. indicum (TMV 7) × S. radiatum (20.15) at eight hours after pollination indicated lower pollen germination per cent. In both the direct and reciprocal crosses, the pollen tubes did not reach the ovary even after eight hours of pollination depicting the presence of pre fertilization barrier and hence capsules were not developed.

Garlic (Allium sativum L.) is one of the important herbs worldwide. Genetic studies on Indonesian garlic germplasm are still limited. We aimed to estimate genetic parameters and analyze the Principal Component of Indonesian local garlic accessions. Augmented Block Design with three replications (blocks) was used to characterize 20 accessions with 16 accessions as ‘Test’ and four check varieties. The research was carried out at Lembang, West Java (1250 m asl) from October 2022 until March 2023. The result showed that from block-adjusted ANOVA, tested accessions gave significant differences in number of leaves, leaf length, ratio between length and width of stomata, and yield per plot. A high genotypic coefficient of variance (GCV) was observed on pseudo-stem diameter, root length, and yield per plot. It also showed that the number of leaves, the ratio between length and width of stomata, and yield per plot had high value of hBS (broad-sense heritability). Our study also showed that yield per plot had positive and significant (p<0.05) correlations with pseudo-stem diameter, leaf length, chlorophyll content, stomatal length, and root length. Principal Component Analysis showed that 82.75% of the total variance can be explained by the first three PCs viz. 57.19%, 15.27%, and 10.29% respectively.
