Maize silks

Maize kernel filling, which is closely related to the process of double fertilization and is sensitive to a variety of environmental conditions, is an important component of maize yield determination. Silk is an important tissue of maize ears that can discriminate pollen and conduct pollination.

Baby corn is the ear and diversified product of maize plant harvested young, especially when the silks have either not emerged or just emerged, and no fertilization has taken place. Field experiments were conducted during October-March, 2012-13 and 2013-14to study the impacts of thermal regime on phenology and yield of baby corn. Thermal environment during reproductive phase of baby corn contributed more towards the yield formation process, as compared to that during vegetative phases.

Maize cultivation for vegetable purpose, such as baby corn is a diversified and value addition in food industries. Baby corn is the female inflorescence in the maize plant, harvested within two days of silk emergence and is sweet in taste and crisp which is a source of foreign earning exchange for India and successful in countries like Thailand and Taiwan has now proven to be a successful venture. The most crucial factors in scientific crop productions are nutrient management. In modern agriculture the knowledge of optimum dose of crop nutrition is of prime concern.

The efficiency of a breeding programme depends mainly on the direction and magnitude of the association between yield and its components and also the relative importance of each factor involved in contributing to grain yield. The path analysis provides an effective measure of direct and indirect causes of association and depicts the relative importance of each factor involved in contributing to the final product.

In order to identify diversity of maize inbred lines, a trial consisting of 15 inbred lines of maize were planted in Randomized Block Design (RBD) in three replication at AICRP Maize breeding field of Dr. Rajendra Prasad Central Agricultural University, Pusa during kharif-2016. The diversity was identified on the basis of morphological data like days to 50% tasseling, days to 50% silking, plant height, ear height, number of grains per row, thousand seed weight, tassel length, tassel branch number, cob length and cob girth.

In the present investigation a total of forty seven maize inbred lines were studied to assess the genetic diversity for 10 quantitative traits viz., days to 50% tasseling, days to 50% silking, days to maturity, plant height (cm), ear length (cm), ear height (cm), 100-seed weight (g), kernel rows per ear, number of kernels per row and grain yield per plant (g) using principal component analysis and hierarchical cluster analysis. The PCA identified four principal components (PCs) with Eigen value greater than 1.00 and accounted for 80.35 per cent of total variation.

The experiment comprised of six F1’s, which were selected based on the combinations of low yield × high yield and low ASI × high ASI. The selected six F1’s were crossed in full diallel mating design to synthesis 18 three way crosses was estimated and validated on the basis of performance of their constituent single crosses. Out of 18 hybrids, TWC 3 recorded lower days to tasseling and silking and hence it can be used further in breeding programme. While, TWC 4 (0.32), TWC 11 (0.5), TWC 9 (0.76), TWC 10 (0.79), TWC 14 (0.81) and TWC 5 (0.89) recorded least ASI.

An experimental study was conducted to evaluate the relationship between yield and its components in maize through correlation and path studies. Yield is the foremost consideration in the breeding of any crop. Since yield depends upon many yield contributing characters, it becomes essential to study the contribution of each character to the yield. Correlation is an important parameter in estimating the relative importance of various characters on grain yield.

Heat stress due to prolonged high ambient temperature during critical growth stages is a serious threat to crop production worldwide. Though being a C4 crop, maize has relatively wider adaptation, however, weather extremes such as heat stress is challenging its threshold limits. There is an absolute requirement of heat tolerant cultivars in the present condition as climate change has a become reality.
