“…Regarding heritability estimates for all traits under study, the results revealed that the broad-sense heritability was higher than the narrow-sense heritability estimates for all characters. Our results corroborated with El-Malky et al [28], Hammoud et al [29], and El-Malky et al [30]. As a matter of fact, a character or trait influenced by non-additive gene action usually show low genetic advance but high heritability, while for the character under additive gene action, heritability and genetic advance values are always high [49].…”

Rice stem borer (Chilo agamemnon Bles.) is a primary insect pest of rice and is a major limiting factor to rice production. Breeding for insect-resistant crop varieties has been an economic way of integrated pest management (IPM) as it offers a viable and ecologically acceptable approach. This study was aimed to evaluate rice genotypes for their resistance against rice stem borer. Seven parental genotypes with twenty one F 1 crosses were evaluated for genotypic variation in field experiments. Analysis of variance revealed significant differences for the studied traits in almost all crosses and parents. In addition, the mean squares of parents versus their crosses were significant for stem borer resistance and other associated traits. Moreover, both general combining ability (GCA) and specific combining ability (SCA) variances were highly significant for all characters studied in the F 1 generation. Based on GCA, 4 genotypes (Sakha101, Gz6903-3-4-2-1, Gz9577-4-1-1 and Hassawi) exhibited highly significant negative values for stem borer resistance (-0.53, -1.06, -0.18 and -0.49, respectively) indicating they are the best combiners for stem borer resistance. Based on SCA analysis, nine cross combinations showed highly significant negative effects for stem borer resistance. Similarly, the cross Giza178ÂHassawi was the best combination with significantly highest value for early maturity. In addition, seven crosses showed highly significant negative SCA for plant height trait. On the other hand, for panicle length, number of primary branches/panicle, panicle weight and 1000-grain weight, seven, four, eight and six crosses showed highly significant positive SCA, respectively. The result further revealed that the non-additive dominance genetic variance was higher than the additive variance for all evaluated traits indicating that non-additive genetic variances have a role in their inheritance. The broad-sense heritability estimates were high for all the studied traits. The stem borer resistance was significantly correlated with panicle weight and 1000-grain weight, which also showed a highly significant correlation with grain yield/plant. Thus these traits can be effectively employed in a breeding program to confer resistance against stem borer infestation in rice. It was further supported by biplot analysis, which clustered these potentially important traits into two quadrants showing their importance in any future breeding program to control stem borer infestation. This study has contributed valuable information for evaluation of genetic diversity in the local rice germplasm and its utilization in futuristic rice genetic improvement programs.

and 2015 seasons, to study the effect of sowing date (15 th of April, 1 st of May and 15 th of May) on grain yield of twenty rice genotypes, and infestation by Rhizopertha dominica (F.). Sowing date had significant effects on all studied characters in both years. The highest values of number of panicles per hill, number of filled grains per panicle, grain yield, hulling, milling and broken rice grain were recorded in the early sowing date. The number of days from seeding to maturity and number of unfilled spikelets per panicle were recorded in the decline trend, as sowing was delayed. Egyptian Hybrid Rice 1 produced the highest values of grain yield followed by Giza179, and Giza178. Sakha106 produced maximum values of hulling and milling percentages. Regarding to the susceptibility of rice varieties to insect infestation by lesser grain borer, R. dominica in storage, data showed that the

“…Sowing date of rice affects degree of rice infestation by the rice leafminer and the rice stem borer, which are the most destructive rice pests. The occurrence and prevalence of insect pests are affected by host plant availability, growth stage, sowing and transplanting dates (El-Malky and El-Zun 2014). Due to the insect pests, there was severe damage to the rice grain yield during the different growth stages.…”

2020 and 2021 seasons. The objective of study was to study the effect of three sowing dates (May1 st , May15 th and June1 st ) on yield, yield attributes of 21 rice genotypes, and infestation by rice leaf miner (Hydrellia prosternalis Deem.) and rice stem borer (Chilo agamemnon Bles.). Sowing date significantly affected all studied characters in both seasons. The highest values of flag leaf area, number of panicles per hill, panicle weight, total number of grains per panicle, percentage of filled grain, 1000-grain weight and grain yield were recorded in the earliest sowing date, while the lowest values were obtained with the latest one. Statistical analysis revealed that the rice genotypes were significantly different in all the studied traits. The highest values of grain yield and most of the studied characters were observed in Giza 179 and GZ10804-3-1-2-2-2, followed by Giza 178 and Sakha 108 rice cultivars. Rice leaf miner infestation significantly increased as the sowing was later. Giza 178 and Giza 179 rice cultivars suffered the highest infestation, followed by GZ 9399-4-1-1-2-1-2 and GZ 10778-17-1-6-1 promising lines. The rice stem borer infestation significantly decreased by delaying the sowing date. GRYT-26-17-178, GRYT-29-17-178 lines and Korea 27 rice genotypes recorded the highest infestation with both dead hearts and white heads.
